For my 2nd PComp assignment, I created a mock up of a football (soccer) Goal training net. A full scale version of this can be used for goal scoring training. The sensor can be placed/activated on specific spots, so the player can practice scoring to those spots.
This circuit is comprised of an LED bulb, a resistor and a switch. As shown in the photo below.
I removed the touch switch and added to wires that upon simultaneous contact with foil would cause the LED to light. I added additional foil to one end of the switch to create a larger surface for the ball to hit and make contact with the goal. The goal is made of cardboard covered in foil.
How it works:
- The player kicks the ball toward the ‘net’ i.e. the foil wall – currently being guarded by the goal keeper
- Upon impacting the sensor, the LED lights indicating a goal was scored in the desired spot
