MERKUR Board Basic PICAXE, ULNMod, LED 2x1, Speaker, Button, Potentiometer
Using Picaxe can easily generate sounds of different frequencies. In this simple experiment we will try to generate sounds, tunes, and pulses. The program uses two potentiometers and one button. The output will be mainly a speaker and LED indicator.
Programs can be easily modified for other types of PICAXE microcontrollers.
