Circuit Diagram
The MAX7219 IC connects to the 7-segment display and communicates with the Arduino over SPI to display numbers or characters on the display.
Steps for the Experiment
- Connect the MAX7219 IC to the 7-segment display.
- Wire the MAX7219 to the Arduino using the SPI interface.
- Upload the program to the Arduino to control the 7-segment display via the MAX7219 IC.
Explanation
The MAX7219 is used to control the 7-segment display with minimal wiring and complexity, using SPI communication from the Arduino to drive the display.
Results and Observations
- The 7-segment display should show numbers or characters as programmed in the Arduino code.
