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...
