Arduino Uno Super Starter Kit Digital Inputs

We will now be looking at using digital inputs (pushbuttons) to turn LEDs on and off. This will be programmed using our Arduino Uno R3 from our Super Starter Kit. Pushbuttons will allow actions to be performed that our Arduino program sketch will interpret and take action. We will be wiring two pushbutton switches. A pull-down resistor will be wired to the first switch and a pull-up resistor will be wired to the second switch. This will change the state of the input (High (1) or Low (0)) based on the wiring. Two LEDs will be wired to the outputs of the Arduino Uno. This will show the state of the switches and allow the switch inputs to modify the state of the LED. We will look at a couple of different programs. Eliminating switch bouncing will also be discussed and programmed using our Arduino Uno super starter kit. Let’s get started.
