Recover bricked attiny using arduino as high voltage programmer

Hi! Today I’ll explain you how to recover your bricked ATtiny microcontroller using your Arduino board. ATtinys are very popular due to their small form factor yet very powerful. While working with them you may accidentally brick the ATtiny. As arduino is extremely popular and really easy to use, I guess you have one or more lying on your work table. You don’t need to purchase a HVP (High Voltage Programmer), or search for an old PC with parallel port to recover ATtiny. Just build a small circuit, plug it into Arduino board, upload a sketch and you are good to go. So let’s start.”
