@Suhailjr When you post project details, please try to include a picture and basic technical information will be better for understating.

Thanks for sharing 😊 .

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 .

CircuitPython 5.0.0 Beta released.
5.0.0 is the latest major revision of CircuitPython. It features many improvements and enhancements to display io, including grayscale OLED and e-paper displays, extensive additions and improvements to BLE support, support for the STM32F4 and Sony Spresense microcontrollers, and PWM audio support – GitHub.

Attended #KeralaJS September meetup.

All the sessions were very informative and added a bunch of new things to the to-learn list!

The first session by Ganesh (UX Strategist, UX Problem Solver And Lead UI Designer, Tata Consultancy Services, Infopark Kochi) on Visual Approach to presentation design gave lots of good insights and tips on how a presentation should be. It was detailed and mentioned different terminologies and theories in UX and presentation design.

The second session was by Nithin Chandran (Senior software engineer, KeyValue Systems) on Adopting Typescript. He talked about why TypeScript and how it adds value when Dart or Coffee script-like languages are doing the same thing. The key point was how it is easy to adopt TypeScript for a JavaScript programmer.

The third session was by Mahin on RxJS with a Live Demo. He demonstrated what is RxJS and what sort of capability it adds by things like Operators.

The final extempore session by Praseed Pai Kt about why JavaScript is considered as "Glue" language and why it got designed so (dynamic, prototype-based oop, functional constructs ) with the details of history and facts about the context when JS got originally designed by Brendan Eich.

Thank you KeyValue Systems for such an awesome venue and snacks (;-P). Thank you, Nirmal Vyas and all speakers and attendees for such a beautiful event.

Hi @Anudeep ,

MP66050 is a Gyroscope + Accelerometer + Temperature Sensor Module ,

3-Axis Gyroscope

The 3 Axis Gyroscope is used to detect rotational velocity along the X, Y, Z axes as shown in the below figure.

The full-scale range of output is +/- 250, +/- 500, +/- 1000, +/- 2000 , and that is the angular velocity represented in units of rotations per minute (RPM), or degrees per second (°/s). The three axes of rotation are either referenced as x, y, and z, or roll, pitch, and yaw.

3-Axis Accelerometer

Accelerometers are devices that measure acceleration, which is the rate of change of the velocity of an object, it can be used to detect the angle of tilt or inclination along the X, Y and Z axes as shown in below figure.

They measure in meters per second squared (m/s2) or in G-forces (g). A single G-force for us here on planet Earth is equivalent to 9.8 m/s2, but this does vary slightly with elevation (and will be a different value on different planets due to variations in gravitational pull)

@hackitajce
Hi,
Is the hackthon focusing on any special technology or domain?

@Abhay Thanks for sharing. Simulation is very helpful.
