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.
