The common firmware(-directory) now is also capable to compile firmwares for different tinyusbboard (16MHz/20MHz, atmega8, atmega88p, atmega168p, atmega328p) types. Attach any I2C client chip (thermo ...

A simple CW beacon controller for AVR ATtiny45. It's an old project. You can take it as is and only change the text of the transmission. If you have questions I'll try to answer them. To compile the ...

The project uses the ATtiny45 to connect to the USB port in order to create a LED notifier that can be attached to the EeePC. The schematic shows the pin 8 of ATtiny45 being connected to the USB port ...

If you’re looking for a DIY amplifier project made with a minimum of parts, this is the build for you. [Rouslan] created a 70 watt class D amplifier using an ATtiny45 and just a few dollars worth of ...

Servo8bit is a library for AVR microcontrollers that allows you to drive servo motors without the need for a 16-bit timer. Obviously, this is quite useful for smaller chips that only have 8-bit timers ...

The Caps Locker is a device that plugs into a USB port and takes control of a computer’s Caps Lock key which switches it ON/OFF at 30-second to 8-minute intervals. The circuit was built around Atmel ...

This very simple little development board was designed for carrying out tests on the 8-pin AVR microcontrollers from Atmel. Any 8-pin IC with power on pins 8 (+5 V) and 4 (0 V) can be used, checking ...

Here is a simple, little circuit that makes loud, useless noises with an ATtiny45 programed in Bascom-AVR. In the May 1979 edition of Elektor we published a “Simple Sound Effects” unit. The author was ...

The ATTINY45 provides 20 millisecond pulses on either the right turn output or the left turn output. The ATTINY84 provides 20 millisecond pulses on either the right turn output or the left turn output ...
