A couple of weeks ago (better late than never) (I am currently going through my log book from school posting anything that we did and might be interesting) we put motors, LED lights, buzzers and lights onto battery packs and then later ran the circuit through a switch creating a more complex circuit. This led us to amazing discoveries towards our invention.

When a circuit didn't work we had to trace the circuit and find what the problem was. I taught Ben that when making a circuit you always remember it ends up being one big circle- remember circle circuit!!!

At the time of this invention we were thinking of creating an automatic dog feeder but we soon found that it already existed- it was Ben's idea (a good one i must say), i said that we should make one or buy one and then modify it by putting modern gadgets on it such as lights and buzzers to let say a blind dog know where his food is by hearing a buzzer or a light by letting the dog see whats its eating!!!
