Part 14 had us building a simple circuit to test for flame/heat/fire using a phototransistor. Before building the final phototransistor I put together a test using the breadboard. In addition to the breadboard test, I built a little IR emitter circuit that I would be able to use to test since I knew I was going to use this with my hack-a-toy. Here is my phototransistor test circuit. As well as the circuit reading working displaying values using the Arduino.

Part 13 was a variation of some of the work we had done in some of the previous labs. In this lab we got to use a good bit of pre-formatted code to test the operation of an Ultra Sonic or sound wave based sensor. The lab was just getting the sensor to work with some pre-created code. Here is the code I used to test …

For my Hack-A-Toy project I decided to overachieve a little bit knowing that we would be creating a robot to blow out a candle later in class. In my case I took one of a pair of old radio controled sumo’s that I wanted to get to move and find a heat source. Here is a picture of what the toy looked like before I started hacking.
