Make the Attiny85 run for years on low power mode: Do not waste time and money on this item. It took me some time to realize that this is no programmer at all, it's just a breakout board so you don't need the breadboard and there is the ICSP pin laout. "1PCS Development Programmer Board for ATtiny13A/ATtiny25/ATtiny45/ATtiny85" from ebay store. Al that really happens is that most connections are labelled differently (i.e. While using a normal Arduino IDE as an ISP programmer I had a look at designs for a high voltage programmer and realised that there are minimal extra connections required to turn the normal programmer into an HVP programmer. I have all excited also bought so called: Unbrick ATtiny Hardware Convert AVRISP programmer to HVP. If all was done right, the LED connected to Attiny85 hw pin 2 should blink with 1s period. In the IDE select Board: "Attiny", Processor: "Attiny85", Clock: "1Mhz Internal", and as a programmer select "Arduino as ISP". Modify the PIN to blink to PIN 3.Ĭonnect the Attiny pin 2 (numbered by hardware layout, this is referred as PIN3 in the program) another LED and 220R resistor to see if the chip is programmed well. For testing choose the Blink sketch from the basic examples. In other window of Arduino IDE you may upload the Attiny85 program.
