It’s now time for start planning for the wireless sensors. I have the wireless transmitter and arduino nano at home, just waiting for some electric components to arrive to start working.
The wired game is done.
I made it in an water proof case. The piezo sensors is added behind the target to collect the vibration from the bullet in the steel wall in the target.
The system can be powered from an 9v battery or with an cable. I have an switch that i choose the power to the game.
