Examples

Analogue Input

Basic example of how to read an analogue input on the MIAC and display it on the LCD. MIAC ADC LCD

Keypad Input

Basic example of how to read the keypad and display the value on the LCD. MIAC Keypad For reference the numbering of the MIAC keypad looks like this.

Output Control

Basic example of how to control all of the individual outputs on the MIAC using the keypad.

Note that for the transistor outputs to come on you must wire a connection from the +V terminal to the M terminal.

If you are driving high current outputs then you can instead supply separate DC power to the M terminal. MIAC Outputs

MIAC Interrupt Controlled Clock

Basic example of how to create a timer interrupt based clock. MIAC Clock
