All – using the serial monitor with an Arduino. Totally useful.
1. create a new circuit in Tinkercad with two leds.
2. change the code so that is has this sequence:
>first LED on
>first LED off
>second LED on
>second LED off
3. we will add the code for a serial monitor into your program.
4. now it’s time for the real thing. The Arduino. I will give each of an Arduino and a cable.
