Uno to ATtiny85 / 13 programmer

Just an ATtiny 85 / 13 programmer that can be mounted on Arduino UNO, with an led on PB3. Simple and elegant solution if you need to program many ATTiny85 / 13 microcontrollers.

You can also hook up a SOIC8 adapter like this one : https://www.aliexpress.com/item/32707843336.html on top of the female header pins so you can also use it for SMD packages.
