Circuit Diagram
The following diagram illustrates how to connect the ATtiny85 to the 7-segment display:
Steps for the Experiment
- Connect the 7-segment display to the ATtiny85 pins according to the circuit diagram.
- Upload the program to display numbers on the 7-segment display using Arduino IDE.
- Power the ATtiny85 and observe the numbers displayed on the 7-segment display.
Explanation
This experiment uses the ATtiny85 to control a 7-segment display, enabling the display of digits. The program sends signals to the segments of the display to form numbers.
Results and Observations
- The 7-segment display should show the numbers as programmed.
- The display can be modified to show different numbers or sequences.
Applications of the ATtiny85 with 7-Segment Display
The ATtiny85 with a 7-segment display can be used in simple digital clocks, counters, or other small-scale embedded systems.
