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
Wire the ATtiny85 breadboard with photocell and LED
Design the schematic and use circuits.io to make the diagram.
Upload the code using "/Sketch/Uploading Using Programmer"
This video shows how it works:
