For beginners as well as intermediate makers i prefer Arduino Micro or Leonardo. It is very easy to use like an Arduino UNO or Nano and has the same features of ATmega328P as well as a must-have feature support built-in USB and can use it as a USB host Device or HID device. I also prefer Arduino Nano boards rather than using Arduino UNO boards because of its size only.

For simple and minimal projects i love to use ATtiny 16/84/85 microcontrollers(My own boards) or digispark boards. It is cheaper smaller in size and works with ultra-low power mode.

In the IoT perspective, I prefer ESP8266/ESP32 boards if you want to add wifi/BLE features into your project. The cheapest and the best solution for IoT projects so far. Have large community support and supported by different programming platforms like Arduino IDE, MicroPython, ESP IDF, etc.... Esp32 is a powerful 32-bit microcontroller capable of wrapup any heavy project we think!

@Raman woow. Can you share what's the product about with us if it's okay with you??

@kowshik1729 You can find the sensor Operating Instructions here. since it's an industrial one, Arduino instruction will not available out of the box! but we can contact the manufacture regarding the communication protocols to write driver/ interfacing programme fo this.

Now we can participate in Maker Faire 😋 Thanks for sharing

@nikhilrishi hi sir, my self navin dusa
I have used ESP8266 and ESP32-CAM
for door locks with proximity sensor

Door will be unlocked using face recognition AI module and also with Voice, Android app and manual key

I have also added some features rfid and fingerprint with raspberry pi
I also have good experience in electronics field

I recently worked for smart doorlocks project
And successfully implemented in hotel rooms
Thank you 😊
Pls reply sir

@SuperGops When you want to create a PWM signal, why don't you just use

to just create your PWM? Is there any specific reason you are going for interrupts?
