Tutorial 4 for Arduino: Analog Inputs

| 114 Comments

This tutorial was featured on the official Arduino blog on 3/9/2011

This week is all about analog inputs for the arduino. I’ll show you how you can use a voltage divider circuit (see episode 3) and a variable resistor to make an analog sensor. We’ll also use a Sharp IR distance sensor as an analog input to detect distance and movement (with some clever programming). By the end of this episode, you will be able to create your own emergency lighting system! Without further adieu, check out this week’s tutorial on analog inputs for the arduino…

One more thing: You only have 1 more week to submit your arduino projects and win a soldering station – get going!
