ExaMPLE #1
Remote LED blinking
Here a simply circuit consisting of two Arduinos with the following connections:
- Pin 0 (RX) on the Arduino #1 goes to pin 1 (TX) on Arduino #2
- Pin 1 (TX) on the Arduino #1 goes to pin 0 (RX) on Arduino #2
- Arduino #1 GND to Arduino #2 GND
- Arduino #2 D2 to LED + Resistor (220 or 330 ohm)
