LED with a Button

LED with a Button#

Building on the last tutorial, we are now doing to introduce input components into our circuit. You will need the components listed below.

Component list

  • Microprocessor (for these examples either Arduino Uno or Raspberry Pi Pico)

  • Breadboard

  • Pushbutton

  • LED light

  • 2 x 220 Ω Resistors

  • 5 x M/M wires

A button acts as a simple digital input, by only allowing current to flow through it when pressed.

What’s new?

  • Handling digital inputs

  • if/else statements
