by adding memory to a push button switch, you can create an Arduino toggle switch.All you need is a variable associated with the push button input which you invert every time the button is pushed.A Program that Might Work!The following sketch uses digitalRead and toggles an LED output using...
Arduino Tutorial 29: Using Push Buttons to Create Dimmable LED September 24, 2019 In this lesson we show you how to create a Dimmable LED using two pushbuttons. Pressing one button will gradually increase the brightness, while pressing the other button will gradually decrease the brightness. ...
If you want to use this with a higher voltage, say 12V or 24V, simply add a 470 ohm resistor in series with the LED connection to keep the LED current at around 20mA.This button is a momentary push button, when you press it the 'normally-open' contact shorts to the common contact....
