Circuit Binding - Day 2

6 October 2010, Wednesday

Today, I've finished building the bread board and readying for the testing. When the battery have installed, it work perfectly fine (thank god!). The sound is similar to the computer error sound when start up the computer. Also, the tone of the sound will high and low by changing the resistor. The sound amplifier is really strong and sounds only one tone. I think I have to develop more.
