Pic-1: Raspi type display Pic-2: Raspi type pin position Pic-3: Arduino type display Arduino style – Directly sits exactly on an Arduino UNO board. The major disadvantage is that once it sits on an ...

So, Arduino Rx is pin 15 and Arduino Tx is pin 14. The 8-pin male pin header can be replaced by a right angle pin header to change the orientation of the Pi-OBD module.

A 1kΩ resistor is put in between the Arduino digital pin 9 and MP3 module's RX to drop the voltage down from the Arduino’s 5V. Programming Arduino Nano for Decorative Christmas Tree Once we are ready ...

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led – the green one on the left in the photo. And it has a pair of yellow leds – called TX ...
