Hi @ZeeZa ,
You need to build a custom board with the ESP32 SoC and the MPU6050 IMU, right?
first, you need to select appropriate ESP32 SoC from the wide variety of model, after that using the datasheet find out the minimum configuration circuit for the SoC and add the MPU6050 module. that's all you need. the most tricky part is the minimum configuration circuit.
Hi @Geethesh, If you are building simple POC (Proof of concept ) or Quick prototype then the HC-05 is enough with the ATtiny.
For the ATtiny45 minimum circuit you only need one Pull up resistor for Reset, and one Filter capacitor between VCC and ground and you also need to populate ICSP pins for programming
You also need only two external componts HC-05 and Buzzer .
In the this project we did't require any external oscillator , the internal 8mhz should be fine .
Hi @kowshik1729 ,
Yes, you can do Multi Thread in Raspberry Pi using python and note that different threads do not actually execute at the same time: they merely appear to.
We can easily implement simple threads using threading module. I'll show you some example of how actually it works.
Example :
I was trying to blink two LED's at the same time, for that I created a function that does the blink infinitely using while(True) .
import RPi.GPIO as GPIO
import time
Rled = 12
Bled = 6
GPIO.setmode(GPIO.BCM)
GPIO.setup(Rled,GPIO.OUT)
GPIO.setup(Bled,GPIO.OUT)
def blue():
while True:
print "LED BLUE is ON"
GPIO.output(Bled,GPIO.LOW)
time.sleep(1)
print "LED BLUE is OFF"
GPIO.output(Bled,GPIO.HIGH)
time.sleep(1)
def red():
while True:
print "LED RED is ON"
GPIO.output(Rled,GPIO.LOW)
time.sleep(1)
print "LED RED is OFF"
GPIO.output(Rled,GPIO.HIGH)
time.sleep(1)
blue()
red()
Output :
Video : https://www.youtube.com/watch?v=AypMEQFpEWo&feature=youtu.be
since we are using the infinity loop for both methods, the blue() will not stop and red() will not invoke either.
In these scenarios, we can use multithread both function without waiting for another , let's try.
import RPi.GPIO as GPIO
import time
import threading
Rled = 12
Bled = 6
GPIO.setmode(GPIO.BCM)
GPIO.setup(Rled,GPIO.OUT)
GPIO.setup(Bled,GPIO.OUT)
def blue():
while True:
print "LED BLUE is ON"
GPIO.output(Bled,GPIO.LOW)
time.sleep(1)
print "LED BLUE is OFF"
GPIO.output(Bled,GPIO.HIGH)
time.sleep(1)
def red():
while True:
print "LED RED is ON"
GPIO.output(Rled,GPIO.LOW)
time.sleep(1)
print "LED RED is OFF"
GPIO.output(Rled,GPIO.HIGH)
time.sleep(1)
t1 = threading.Thread(target=blue)
t2 = threading.Thread(target=red)
t1.start()
t2.start()
Output :
Video : https://www.youtube.com/watch?v=HMKYzgdNwd8&feature=youtu.be
with the help threading module we can simply run both methods at the same time (how we feel).
I think you got your answer. also, keep in mind to avoid race condition and deadlock while multithreading.
Hi @Abhay ,
I don't know what exactly your application is or what you are going to do with the data is ? if you want to read vehicle data you can use OBD-II CAN-BUS development kit. also for the esp vs raspberry pi decision is also depends upon what you are doing with the data.
Hi @SalmanFK ,
You can Serialize the data as a JSON or CSV string format and publish that as a single string, so you get the data in a single node, you also DeSerialize the string simply in the application end.

Hi @Abhay ,
Like @swalahamani said there are many proving IoT data harvesting and visualizing tools. The trickiest part is choosing right that suit for your application and your stack.
we can categorize the tools into two categories Industrial specific and prototyping based on the architecture and cost.
Industrial specific service
These tools are Industry and product ready ones if you are really looking to space where you can expand your IoT product into larger userbase then these for you.
AWS IoT Platform
AWS has broad and deep IoT services, from the edge to the cloud. Device software, Amazon FreeRTOS and AWS IoT Greengrass, provides local data collection and analysis. In the cloud, AWS IoT is the only vendor to bring together data management and rich analytics in easy to use services designed specifically for noisy IoT data.
Google IoT
Cloud IoT Core is a fully managed service that allows you to easily and securely connect, manage, and ingest data from millions of globally dispersed devices. Cloud IoT Core, in combination with other services on the Cloud IoT platform, provides a complete solution for collecting, processing, analyzing, and visualizing IoT data in real-time to support improved operational efficiency.
IBM Watson IoT Platform
IBM Watson IoT Platform is a managed, cloud-hosted service designed to make it simple to derive value from your IoT devices. Watson IoT Platform and its additional add on services - Blockchain service and analytic service - enable organizations to capture and explore data for devices, equipment, and machines, and discover insights that can drive better decision-making.
Oracle Internet of Things Cloud Service
Oracle Internet of Things (IoT) Cloud Service is a managed Platform as a Service (PaaS) cloud-based offering that helps you make critical business decisions and strategies by allowing you to connect your devices to the cloud, analyze data from those devices in real-time, and integrate your data with enterprise applications, web services, or with other Oracle Cloud Services, such as Oracle Business Intelligence Cloud Service.
Microsoft Azure IoT
Enable highly secure and reliable communication between your IoT application and the devices it manages. Azure IoT Hub provides a cloud-hosted solution backend to connect virtually any device. Extend your solution from the cloud to the edge with per-device authentication, built-in device management and scaled provisioning.
--> I used the Microsoft Azure, Google IoT Core and AWS IoT services and I most satisfied with AWS IoT Services, You can also get free credits when you register for the first time in any of the above.
Prototype specific service
The problem with the Industrial specific service is that we need more time to set up and irrespective of the number either a single device or more it has same higher maintaining cost and time to set up, so I found it's not suitable for rapid prototyping
myDevices Cayenne
Cayenne is the world’s first drag and drop IoT project builder that empowers developers, designers and engineers to quickly prototype and share their connected device projects. Cayenne was designed to help users create Internet of Things prototypes and then bring them to production.
IO- Adafruit
Adafruit IO is a system that makes data useful. Our focus is on ease of use and allowing simple data connections with little programming required.
IO includes client libraries that wrap our REST and MQTT APIs. IO is built on Ruby on Rails, and Node.js.
Thingspeak IoT Platform
ThingSpeak is an IoT analytics platform service that allows you to aggregate, visualize, and analyze live data streams in the cloud. You can send data to ThingSpeakfrom your devices, create instant visualizations of live data, and send alerts using web services like Twitter and Twilio. With MATLAB analytics inside ThingSpeak, you can write and execute MATLAB code to perform preprocessing, visualizations, and analyses. ThingSpeak enables engineers and scientists to prototype and builds IoT systems without setting up servers or developing web software.
--> I used the Cayenne, Adafruit IO and both are really good if you want to build a prototype/POC in a couple of hours.
I hope my explanation is useful, Also there are many services out there like Node-RED, Eclipse Kapua etc. So the choice is actually based on your end goal and what you are going to do with the data.
All the best.
Arduino Fundamentals is an online exam that provides official certification on your knowledge of Arduino related electronics, programming and physical computing.
The exam is based on the concepts introduced in the Arduino Starter Kit, as it offers all you need (components, project book and support) to get started with Arduino, coding and electronics in a hands-on way.
HOW DOES IT WORK?
The Arduino Fundamental exam is web-based and consists of 36 questions with 75 minutes to complete them all.
You will receive your results immediately after submission, indicating whether you passed or failed. By passing the exam you will be rewarded with the Arduino Fundamentals certificate.
HOW DO I PREPARE FOR THE EXAM?
There are no specific prerequisites for completing before taking the Fundamentals exam. However, the knowledge level and concepts tested in the exam closely match the content of the Arduino Starter Kit.
We can, therefore, recommend going through the content of the Arduino Starter Kit Projects book, and building the projects introduced in it.
WHAT IS AN ARDUINO CERTIFICATE?
Official Arduino certificate is a document that affirms your successful completion of the Arduino exam and serves as a guarantee of your competence in the Arduino-related subjects. It could be used to highlight your skills and learning progress, and advance in your career or education.
Arduino certificates use a unique QR code system which enables an instant check of their validity online, making them impossible to forge or copy.
WHAT DO I GET WHEN I PURCHASE THE EXAM?
You get 1 attempt to pass the exam. Once the access is unlocked, you can take the exam right away, or take your time to prepare and come back whenever you feel ready. Remember that the attempt will have an expiration date of 1 year.
WHAT HAPPENS IF I FAIL THE EXAM?
You can try completing the exam again by purchasing another attempt.
At the end of each exam, you will receive feedback about your performance in relation to the different topics covered in the Arduino Fundamentals exam. This information should help you improve, and perform better next time.

Hi @Geethesh , Since HC05 is Interfaced with Serial (UART), you can check whether it connected or not in the Serial.available() function call.
if (Serial.available() > 0) { // Checks whether data is comming from the serial port
data = Serial.read(); // Reads the data from the serial port
}
else {
// Write what you need if serial is not connected
}
full Implementation .
#define led 13
void setup()
{
Serial.begin(9600);
pinMode(led, OUTPUT);
}
void loop()
{
if (Serial.available() > 0) { // Checks whether data is comming from the serial port
data = Serial.read(); // Reads the data from the serial port
}
else {
ledBlink();
}
}
void ledBlink()
{
digitalWrite(led, HIGH);
delay(100);
digitalWrite(led, LOW);
delay(100);
}
All the best .
@Geethesh , keep in mind ATtiny series doesn't have Hardware Serial, so you should use the SoftwareSerial for that you also need two more for UART communication (Rx, Tx) between Arduino and Bluetooth.
