Description
7 segment quadri-counter
Counter
for table football
Hi everyone, this project was all made by myself using different logic port and seven segment display (common cathode).
In particular I’ve used:
- Seven segment display green 2x;
- Seven segment display red 1x;
- Seven segment display blue 1x;
- Resistor 180 Ohm;
- Resistor 120 Ohm;
- Endstop (for trigger);
Logic port:
- CH4511 (one for every seven segment);
- 74hc14;
- 74ls590;
How does it work?
During the game the ball scores into the door, fell over the endstop, triggering the signal and make the point Seven segment encreasing it’s value: Red for red squad, and blue obv for blue team. After 9 point on the board, the team who scores will win, increasing it’s own “match win”’s seven segment (green color) encreasing by 1.
The circuit works with a 220 to 12v transformer, reduced to 5V by 7805 mosfet.
At least I’ve added 4 bottom for the reset of the scores.
