Introduction: Button LED Input/Output Circuit

About: I am robotics engineer and a teacher whose passion in life is breaking down the maths and academic jargon of programming and robotics into something that everyone can understand, primary school kids included.…

This is a circuit which introduces the concept of input / output programming. The output being 4 LED's and the input being a push button. After completing it you have a great platform to experiment with concepts like if functions and booleans.

Components needed:
Arduino X 1 LED X 4

Jumper Wire X 6

Resistor 330 Ohm X 4

Tactile Push Button X 1
