TinyCalibrator is an oscillator calibrator and high-voltage fuse resetter for 8-pin ATtinys based on an ATtiny44/84. Because the 8-pin ATtinys only have a few GPIO pins available, they are usually operated without an external clock. The internal oscillator does a good job in most applications, but when it comes to precise timing, its +/-10% accuracy is often insufficient. Fortunately, t...
TinyHVSP is a stand-alone high-voltage serial programmer and fuse resetter for ATtiny 13/25/45/85. This project was superseded by the more versatile [TinyCalibrator](https://github.com/wagiminator/ATtiny84-TinyCalibrator).

# TinyICOC - AVR In-Circuit Oscillator Calibrator
Sometimes AVRs are operated without an external clock. The internal oscillator does a good job in most applications, but when it comes to precise timing, its +/-10% accuracy is often insufficient. Fortunately, the oscillator can be calibrated, increasing its accuracy to +/-2% or better. There are a few ways to perform this manual calibration, but s...
As the title, LED dimmer. Tired or turing on lights at night just to get blinded by being so bright. This is a small LED dimmer that can be put beside your bed at night table or just stuck to the bed it self.Allows gradual ON and OFF dimming or full ON.
Learning from version 1, version 2 changessecond channel from low to high FET PWM current directly controlled by input ie PIR/motion sensor to. Ad...
2.4GHz Wireless Dev Kit.
Sensor board powered by CR2032 battery. Each sensor board has RJ11 input for landline phone line and three discrete/analog inputs, discrete outputs for other use.
Controller board powered by 12V DC. Controller drives LED strip WS2811. Color of light motion depends on activated sensor and its channel.
Primarely used as an intercom and a landline ring light indicator for peo...

For following controllers:
Example code using Attiny84:
Small development board for using an ATtiny44A or similar 14-pin ATtiny in SMD package on a breadboard.
Minimal hardware design featuring only MCU, breadboard friendly headers with extra power lines, ISP header for serial programming and reset button.
Uses bare chip and limited extra components.
Also usable for ATtiny84, ATtiny441 and ATtiny841.
