137 : Counter
- Author: Jasmin Mittelman
- Description: Counts till 99 when button is pressed and shows light depending if counter is even or odd.
- GitHub repository
- View in Wokwi
- Clock: 50000 Hz
How it works
There are three modules: MyCounter (tests if the button is pressed or released), score (recieves the increment signal from MyCounter and sends the 7 segment information back to Wokwi module), and Wokwi (Takes the inputs from the buttons and clock. Then it sends the information to MyCounter. Next, it sends the information recieved by MyCounter back out to the 7 segment display and LEDs).
How to test
- Click the red button to increment the counter
- Blue LED indicates the counter is an even number
- Red LED indicates the counter is an odd number
- Press the black reset button to reset the counter back to 0
