Introduction

Photocells and thermistors Here we set up voltage dividers for a photocell and a thermistor The code works the same as the potentiometer! Both the photocell and the thermistor are 3K so we set the voltage divider up with 3K resistors (orange-black-red)

Components Needed

• Freeduino or Arduino or clone
• USB cable for Freeduino
• Freeduino development software - download here!
• Solderless Breadboard
• Hookup wire 22gauge solid

How to

• See the fritzing diagram

Schematic

The schematic was to confusing on the Fritzing program. I will try to make it cleaner...
