Independent Work

At the end of last week's class, we had emailed Fab Lab to ask if we were able to play around with their electronics and breadboarding kits, in order to make a prototype for our buzzer alarm clock idea. After receiving confirmation that it was fine to do so, we went in today at around 1pm to get going on it.

We ended up making the breadboarding circuit, using an Arduino as well, in order to create exactly what we wanted. I have attached a photo of the circuit below. The circuit worked fine, and the buzzer would sound whenever the magnet was away from the reed switch. The magnet would then turn off the sound once placed next to the reed switch. We wanted to buy a larger buzzer from JayCar, as this buzzer was reasonably muted.

After making this circuit, and using some code within the Arduino to get it to work, we ended up heading down to JayCar electronics on Adelaide road to purchase some equipment of our own, so that we would be able to show proof of concept at Friday's class. Stu also let us borrow one of his Arduino Megas, which saved us buying one of them, all we needed was a usb cable to connect it to a laptop.
