Breadboard Friendly ATTiny85

Chris @ chris3d.com build his own Attiny85 board:  The modularity of Arduinos is great, but after playing with them for a year or so, I wanted to start building things that needed a little more integration. I also wanted to design the components and programming around the actual...

ATtiny85 Tiny OLED Watch

An ATtiny85 and a 64x48 OLED display hand clock: This is the third in my series of minimalist watches based on the ATtiny85. This version displays the time by drawing an analogue watch face on a miniature 64x48 OLED display. It uses a separate crystal-controlled low-power RTC chip to...

10 or 12-bit DAC from the ATtiny85

David Johnson-Davies @ technoblogy.com writes: This article describes how to get up to two 10 or 12-bit digital-to-analogue outputs from an 8-bit Timer/Counter, such as in the ATtiny85. To test the routine I built a circuit which allows you to vary the brightness of two LEDs with two...

Tiny LED Time Watch

David Johnson-Davies designed a minimalist ATtiny85-based watch using 12 LEDs, arranged like a clock face, to show the time in analogue-style. He writes: To show the time you press the button on the watch face, and the time is then displayed for four seconds. It lights one LED to...
