The 8515  is a microprocessor from Atmel (AVR). It is in a 40 pin package.


Instead of building project with capacitor & resistor and audio
transformer, we build project with "0" and "1". Much cheaper. Much easier
to change. 

This  program displays the result of meteor detect from distant six metre
beacon on matrix of LED; it detects an audio tone from the receiver.

The 7+ includes .png schematic and source code (MSMON.ASM). Is is zipped
with pkzip ver 1.01 .
