Independent Work - Proof of Concept (1)

Today, we decided to meet up again in order to get our proof of concept ready for tomorrow's class. Having been to JayCar yesterday, we had all of the equipment that we would need to create this circuit. I have attached a photo below of the circuit, which is almost identical to the one created yesterday, although with our own equipment, and a larger, noisier buzzer.

Once we set up this circuit, and uploaded the code from the laptop to the Arduino Mega, we were glad to find out that it was working. Below, is a video of the circuit in action, using just a basic magnet to activate the reed switch.

Next, we proceeded to look at ways of putting a magnet inside of a ping-pong ball, which we were planning on using as proof of concept for our projectile. As shown in the photos below, our ideas were to either put the magnet inside the ball, or cut a hole in the bottom to stick the ball in a secure position.

Attached, is a video showing how the magnet/ball de-activates the buzzer.
