One problem solved....
I recently bought an RC car in Hong Kong for $15 USA.
These cheap cars have remote controllers that to not have variable speeds, just
MOTOR +, MOTOR -, MOTOR RIGHT, MOTOR LEFT
This is absolutely perfect for my needs in this shot clock.
I have three controls: RESTART, PAUSE, RESET.
So, I took apart the vehicle and pulled out the circuit board (left)
(Remote controller on the right)
When the FORWARD button is pressed on the remote controller, it sends data over the 27MHz radio wave
The receiving board receives that data and turns on a motor to move FORWARD
Using this circuit, I can replace the FORWARD motor with a transistor
When the receiving board outputs a voltage signal to where the FORWARD motor once was, it will send a signal to the base of an NPN transistor
The transistor will connect the collector to the emitter.
How can i use this?
If you look at my prototype PCB, you will notice that I intended it to be handheld, or to be rested on a table.
Eventually, when this project is finished, I will need to place the PCB on the basketball backboard. The control buttons will be inaccessible to the bench.
So, when that time comes, I will connect the receiving board to the prototype PCB and replace the button switches with transistors.
This way, the bench can control the shot clock,
wirelessly
This is pretty cool to me. I hope it's cool to everyone else too.
This is the shot clock that will change the game.
