TinyHVSP – High Voltage Serial Programmer based on ATtiny84

Stefan Wagner's EasyEDA profile is definitely the go-to source for all things ATtiny. He's built 10s of projects, some of which we have covered here, that are based on the tiny microcontrollers, and it only makes sense that one of his latest projects, called the TinyHVSP, is a tool to...

Nano Current Meter using ATtiny84

David Johnson-Davies published another great tiny project. He writes: This project describes a simple low-current meter I devised to check the sleep current of different microcontroller circuits, such as ones based on AVR microcontrollers. It's capable of measuring currents of between...

Two-Digit Thermometer using ATtiny84 and a DS12B20

David Johnson-Davies shared another nice tiny project. This time is a two digit thermometer based on ATtiny84 and DS12B20 1-Wire temperature sensor. It uses a DS12B20 1-Wire temperature sensor, and an ATtiny84 to drive the display and read the sensor. It's just over 25mm square; about...

Alcohol Unit Counter using ATtiny84

Another great little project is published by David Johnson-Davies and it's about a circuit able to keep track of your alcohol intake. There seems to be a lot of discussion in the news currently about how much alcohol it's safe to drink on a regular basis [1][2]. If you want help in...

Installing The Micronucleus Bootloader To An ATtiny Via Arduino

In order to be able to upload Arduino sketches directly to the ATtiny84 over USB without the need to use a programming device, Shawn Hymel, an electrical engineer at Sparkfun Electronics, had published a guide showing how to install the micronucleus bootloader, which supports virtual USB...

Attiny2313 & Attiny84 V-USB Media Volume Control

Rupert Hirst shares his thoughts on creating a V-USB based media volume control: Although you may think a rotary encoder is just a rotary encoder, when selecting one for a specific purpose such as a volume knob, the feel  and quality can play a large part in your design decision....

Programming an ATtiny with Arduino board

This detailed tutorial shows how to program an ATtiny45, ATtiny85, ATtiny44 or ATtiny84 microcontroller using the Arduino software. The ATtiny45 or 85 is a great option for running simple Arduino programs: it’s small, cheap and relatively easy to use. It does, however, have some...
