Problem
Guests walking by also had the chance to fight back with a water gun powered by an electric pump. However, the pump burned out multiple times due to guests holding down the pedal for too long.
Solution
I limited the amount of time a guest could shoot the water gun by using a simple button-LED circuit on a breadboard which would simulate the action of pressing down the pedal (the button) and the electric pump shooting water out of the gun (the LED).
I wrote a script of Arduino code that only allowed the user to activate the LED for 2 seconds at a time.
Additionally, if 2 minutes have been reached without a user pressing the button, the LED is activated randomly between every 30 seconds and 2 minutes. Once the user presses the button, the script reverts back to its manual mode.
The last step was to wire the Arduino up to the actual pump by using old PLC terminal blocks, a small relay switch, and securing all the components inside a waterproof electrical box.
The new and improved water gun adds an additional level of excitement to the attraction while also making it easier to maintain
