Volleyball-scoreboard

Simple hardware to keep the volleyball score via a small remote operated by one of the players

#Materials

rubber feet/wires you can source them yourself

Wire the screen as shown in the wiring link from adafruit
After completing step 1 you will notice that there are only few pins available therefore we need to use two digital and two analogous pins for the remote wiring; please wire them as follow

int digitalPinA = 13; (Button A)

int digitalPinB = 12; (Button B)

int signalPin0 = A4; (Button C)

int signalPin1 = A5; (Button D)

I opened the battery from Dollarama store remove the USB host and wire the 5V output into both my Arduino Uno power socket (that I also removed) and into the positive input for the LED panel. I cut the positive lead of the power and attached a toggle switch to power on / off the board
upload the code
mount everything inside as the displayed picture. The case is for a Raspberry pi so I had to adapt.
- I used the power socket to install the on off toggle switch.
- I used the USB opening to expose the Arduino USB socket (for future firmware updates)
- I used the LAN opening to vertically mount the mini USB in order to charge the battery. My case was printed from blue PLA and it is pretty transparent allowing the user to see the charge LED blinking.
Test it! In my tests a fully charged battery was good for 3 hours. Dollarama battery is only a 1800Mah so using a 2600Mah should provide at least an extra hour.

Possible future improvements

a new case for this very purpose
multi sport (e.g. basketball, tennis)
a better battery
use the Arduino USB socket also for charging(e.g. when the toggle switch is off) and rid of the mini USB.
and last but not least display at some point the battery level since currently it dies suddenly when a threshold in the battery voltage is being reached.
