Digispark Attiny85 Programming How To Program AProgramming ATtiny85 with Arduino Uno Project tutorial by Arjun Ganesan 403,381 views 100 comments 268 respects Project tutorial Programming ATtiny85 with Arduino Uno GPL3 Step by step on how to program a ATtiny85 microcontroller with Arduino Uno development board.These require only few PWM pins so using multiple Arduino Uno would be expensive and unnecessary.So I decided to use ATtiny85 microcontroller in place of Arduino Uno development boards.
ATtiny85 is a cheap and powerful alternate when u dont need too many PWM pins. Since ATtiny85 is just a microcontroller we need a Arduino Uno to program it. ATtiny85 Pin Configuration Configuring Arduino Uno as a ISP (In-System Programming) To program the ATtiny85 we need to first set Arduino Uno in ISP mode. Open Arduino IDE and open the ArduinoISP example file (File - Examples - ArduinoISP) and upload it. Adding ATtiny85 Support to Arduino IDE By default Arduino IDE doesnt support ATtiny85 so we should add ATtiny boards to Arduino IDE. Open File - Preferences and in the Additional Boards Manager URLs give this url. After this is done open Tools - Board - Board Manager After opening Board Manager scroll down the list where it says attiny by Davis A. Mellis. Click on that and install it. After installing now you would be able to see a new entry in the Board menu Connecting ATtiny85 with Arduino Uno Now with all the above things ready we will start programming the attiny85. Connect the arduino uno to attiny85 using breadboard as below. Arduino Uno ATtiny85 5V Vcc Gnd Gnd Pin 13 Pin 2 Pin 12 Pin 1 Pin 11 Pin 0 Pin 10 Reset Add a 10uF capacitor between RESET and GND in arduino. ![]() If you are using a electrolytic capacitor make sure the anode goes in GND of uno. Then make sure Arduino as ISP is selected under Tools - Programmer By default the ATtiny85 runs at 1MHz. You will get the above message if burning bootloader was successful. Now open the Blink example from arduino examples and change the pin number from 13 to 0 and upload. ![]() There it is the blink program running on a ATtiny85 with just a battery cell to power it. You can do many projects with low cost, low power and low space. Only your imagination is the limit here and the number of PWM pins of course. Making it into a Shield I converted the above circuit to a shield compatible with Arduino Uno.
