You can upload any Arduino-compatible code in this way and make your own projects. Step 7: Push Button *The above demonstration shows how we can use digital output but now we are going to see how we are going to use digital input. ...
Controlling the LED using the delay would have been simpler for you, now try controlling the LED with a push button. Complete detailshere. Once you ace the LED simulations, try this out where get the readings from a Potentiometer. Full detailshere. ...
