We had already seen the circuit for programming ATtiny45 / ATtiny85 using Arduino uno in my previous post. ATtiny45 / ATtiny85 has fewer number of analog and digital pins. So, for bigger applications, we have to go for microcontrollers having more analog and digital pins. ATtiny44 / ATtiny84 is an example of such kind of microcontrollers. Here, we will see a method for programming ATtiny44 / ATtiny84 using Arduino uno.
Circuit is done as shown in the following diagram. An LED should be connected to the 13th pin of ATtiny44 / ATtiny84 to test the program.
Select Arduino Uno board from Tools menu.
Upload the ArduinoISP sketch to your Arduino uno.
Change the digital pin number from 13 to 0.
Select ATtiny board from Tools menu.
When ATtiny board is selected, a Processor sub-menu will appear under Tools menu. Select your processor from Processor sub-menu. My processor is ATtiny44.
Upload the modified Blink program to your ATtiny44 / ATtiny84. If uploading is successful, LED connected to ATtiny44 / ATtiny84 will start blinking.

Step 1 :
Disconnect the capacitor from the circuit (Capacitor connected between RESET and GND pin of Arduino uno).
Upload the ArduinoISP sketch to your Arduino uno.
Step 2 :
After uploading the ArduinoISP, connect the capacitor in the circuit (Capacitor connected between RESET and GND pin of Arduino uno). Then, open Blink program from your sample programs.
Change the digital pin number from 13 to 0.
Select ATtiny board from Tools menu.
When ATtiny board is selected, a Processor sub-menu will appear under Tools menu. Select your processor from Processor sub-menu. My processor is ATtiny44.
Upload the modified Blink program to your ATtiny44 / ATtiny84. If uploading is successful, LED connected to ATtiny44 / ATtiny84 will start blinking.
