Homemade Hardware - Week 1: Breadboard ATtiny85

This week we use Arduino UNO as ISP to breadboard an ATtiny85


Test the photocell

Choose photocell as the sensor to control an LED, test it as with Arduino UNO



Wire the ATtiny85 as the pinout diagram


Get the Arduino set as ISP

Find the code example of Arduino ISP and upload it to Arduino UNO

Install ATtiny Package, change the setting and burn the Bootloader

Highlight Here: Programmer: Arduino as ISP (not ArduinoISP)

the original programmer: AVRISP mkII
