I just had a few questions: Why did you choose to use the Light Sensor Communication as opposed to say Bluetooth Communication? You have only 1 slave so bluetooth would work for communication between the Master and Slave and the communication works 2 ways so the Master can recieve a message back when the Slave has finished its task. I’m guessing it might be because of some delay in communications but there is a slight delay in your current method as well…
Thank you! To answer your questions: I don’t know how to do bluetooth, and I liked the idea of flashing lights :). I agree that bluetooth would probably be a load faster, and I wanted to try using it. The problem was I didn’t have time to learn it (I was moving to the US, so I had to take it apart :()
