CdS Light Sensor:
For this project we will be using 9 light sensing CdS. These simple and easy to use sensors are tremendously useful in a good deal of projects. I recommend buying these from digikey as they are a fraction of the national chains pricing.
ProtoBoard:
For our pinout for the interface on our arduino we used a simple protoboard so we could use a wave shield for future experimentation. The case has enough height to support a shield on the arduino so we may as well use the space wisely.
Brass Hardware:
We picked up some brass hardware to hold the top wood bars to the base box. 4 screws at 1.25” will cost you about 5.00 but cosmetically its worth it.
Speaker:
The speaker we used in this project was the Altec Lansing Orbit. We used it for a couple reasons. First off is the sound quality, it absolutely will surprise you with how good it sounds and the bass that it can put out. Secondly the onboard amp that is 5V native. Lastly is the simple interface of a mono phono cable. This allows us to use simple beep output, or complex sounds with a waveshield simply.
Arduino:
Finally and most importantly the world famous Arduino. This little MCU has been the most fun I have spent 30.00 on that I can remember. Absolutely a must for the tinkerers out there.
