Circuit Diagram
The following diagram shows how to connect the ATtiny85 to the LED for blinking:
Steps for the Experiment
- Connect the ATtiny85 to the programmer and upload the LED blinking program using Arduino IDE.
- Connect the anode of the LED to pin 0 of the ATtiny85 and the cathode to ground through a 220Ω resistor.
- Power the ATtiny85 and observe the LED blinking at the programmed interval.
Explanation
This experiment demonstrates basic microcontroller programming by using the ATtiny85 to blink an LED. The program turns the LED on and off at a specified interval, showing how microcontrollers can control external devices.
Results and Observations
- The LED should blink on and off at a regular interval as per the program.
- The program can be modified to change the blinking speed or pattern.
Applications of the ATtiny85
The ATtiny85 is useful for small embedded systems and low-power applications where space and power consumption are critical.
