[CNLohr] has made a habit of using ATtiny microcontrollers for everything, and one of his most popular projects is using an ATTiny85 to generate NTSC video.With a $2 microcontroller and eight pins ...

Literally, ATtiny85 is a scaled-down version of the Atmega microcontroller on Arduino boards with just a few I/Os (five usable pins) that can listen to or talk to most sensors and transducers.

[Ralph] wasn’t satisfied with the required 5 control pins to drive his nrf24l01+ transceiver module, so he used this circuit needing just 3 pin using an ATtiny85. One of the key components wa… ...

The reset pin (pin 1) can also be used as a (weak) I/O pin. ATtiny with USB Boot Loader: Tips & Tricks for DIYers. DIYers building a development board similar to this one, and looking for applications ...

Features of the Arduino Learning Kit ATTiny85 and Programmer Board : – Support For the Arduino IDE 1.0+ (OSX/Win/Linux). – Power via USB or External Source – 5v or 7-35v (Automatic Selection).

The pins were cut back and the electronics installed, which included Zener diodes flattened with a grinding wheel, capacitors and an ATtiny85 microcontroller.

My version has all the components on one side and a decoupling capacitor, and can be seen in operation in the photo running the classic Arduino Blink programme, set to flash the led that is soldered ...

Anyway, the set-up I used for programming the ATtiny85 is also suitable for programming the 14pin ATtiny84 but, oh woe, my project needs one more pin than is available on the ATtiny84. Frustratingly, ...

The result was the tiny ATtiny85 based Arduino Nanite, ... “Apart from the size considerations, the Nanite also uses a neat circuit trick to share a single pin with the LED and the reset button.
