Step 13How the circuit works
How the circuit works:
The MemAxe circuit is based around the Picaxe 08M microcontroller. The 4 different switches correspond to different sounds that are played. Each of the 4 switches are connected to a resistor which makes a voltage divider that produces a unique voltage when a switch is pressed. The voltage is sensed by the ADC (analog to digital converter) on the Picaxe and converted into one of 4 values in the program. The sound command is then used to output the sound to the speaker. A LED is fitted to one of the digital output pins to indicate when you need to press a switch.
