Arduino Heat

I’ve been playing about with the Arduino the last few weeks. It hooks up through the computer’s usb port and can be used to take in signals from buttons, sliders, dials, sensors or whatever and can also control devices connected to it from the pc.

It can also act as a standalone device and can be programmed… so for instance you could have a microphone as an input device, have a lamp connected to the output and then program the chip so that the lamp switches on when you clap your hands.

The pdf book from provides a great introduction to how it works, including how to build your own ‘Virtual Etch-A-Sketch’. I’ve managed to make a heat sensor control an interactive piece built in macromedia director, so quite pleased with that!

  1. Hey, I’m working with Arduino on a group project for a class on Tangible User Interfaces. We want to use a heat sensor for something, but I can’t find much info on which one to use, etc.

    Could you pass along any info about what heat sensor you used, any tutorials about coding with it, or any other info?


  2. Hi Aylin it’s a 100k thermistor, I used the circuit + code for reading from a light sensor plugged into an analog pin as shown in the pdf booklet from along with the serial xtra for director (plus the sample director file) from – hope that helps!
