This ATtiny 85/45/25 programmer works only with Arduino UNO R3 and R4 boards. If you have Arduino UNO R2, please contact me!

Options:

• With the first option you will get the ATtiny programmer board
• With the second option you will get the ATiny programmer board with 1 ATtiny85-20PU DIP8 chip
• With the third option you will get the ATiny programmer board with 2 ATtiny85-20PU DIP8 chips
• With the fourth option you will get the ATiny programmer board with 5 ATtiny85-20PU DIP8 chips

With every board, there is an additional DIP8 socket included. For frequent use, it is recommended to insert ATtiny into the DIP8 socket and then to the programmer. This method will decrease the risk of bending the legs of ATtiny!

How to use it:

Installing libraries:

• Open ArduinoIDE
• Press File >> Preferences
• In Additional boards manager URLs paste the following link
• https://raw.githubusercontent.com/damellis/attiny/ide-1.6.x-boards-manager/package_damellis_attiny_index.json
• Click OK, restart the Arduino IDE
• Go to Tools >> Board: >> Boards Manager
• In the search box type attiny
• Search for attiny by David A. Mellis
• Click Install
• Restart the Arduino IDE
• Your ATtiny boards will be in Tools >> Board >> attiny

Uploading the code:

• First and foremost, insert the programmer board on the Arduino UNO board
• Place the ATtiny chip in the socket, aligning its hole with the white circle on the board. Bad orientation can cause damage to the chip!
• Plug the Arduino board to the PC
• Open ArduinoIDE
• In tools select your board, port(where Arduino UNO is connected), clock and processor
• Press Sketch >> Upload Using Programmer

If you are using an ATtiny bought from me or your own NEW ATtiny, you need to burn the BOOTLOADER first!

Burning the BOOTLOADER:

• Insert your ATtiny and connect to the PC
• In the Tools, select your Board
• PORT to which Arduino is connected
• Processor - your ATtiny board
• Programmer >> Arduino as ISP
• Press Burn Bootloader
• After that is done, you can upload your code
