| In this project an AVR microcontroller type ATtiny2313 acts as a variable frequency divider, giving a sequence of very stable reference freq...
| With all the processing power under the hood of the Atmel ATtiny13 and ATtiny2313 micros, it’s not too difficult to get them interfaced to t...
| This is a reaction timer game between two players, red and green. Each player has a pushbutton in front of him that he must press at just th...
| Most small function and signal generators do not have a very accurate frequency control and do not offer a built-in frequency counter. Help...
| A voice changer that emulates a so-called Cylon voice can be implemented with the help of a small microcontroller. Those of you who have wat...
| The very simple transmitter described here will let you test RDS equipped receivers and investigate faults, and could be used as the basis f...
| A small microcontroller like the ATtiny15 is ideal for many simple tasks not requiring too much I/O activity. The ATtiny15 has two I/O conne...
