It’s possible to transfer your Arduino sketches on ATtiny85 by using Arduino Uno (in this example) as ISP programmer.
Setup:
- Upload “ArduionISP” sketch (which is found in default Arduino examples) in to your Arduino. Now it became programmer, than do the connection below.
- Download ATtiny board definitions and install like; Documents > Arduino > hardware > attiny > avr
- Select
- Tools->Board->ATTiny
- Tools->Clock->8Mhz (internal)
- Tools->Processor->ATTiny85
- Tools->Programmer->Arduino as ISP
Connections:
- Arduino +5V —> ATtiny Pin 8
- Arduino Ground —> ATtiny Pin 4
- Arduino Pin 10 —> ATtiny Pin 1
- Arduino Pin 11 —> ATtiny Pin 5
- Arduino Pin 12 —> ATtiny Pin 6
- Arduino Pin 13 —> ATtiny Pin 7

void setup() { // initialize digital pin 0 as an output. pinMode(0, OUTPUT); } void loop() { digitalWrite(0, HIGH); // turn the LED on (HIGH is the voltage level) delay(100); // wait for a second digitalWrite(0, LOW); // turn the LED off by making the voltage LOW delay(100); // wait for a second } |
