We had our fourth in the series of Ardunino hardware meetups tonight. Peter was in charge, and he had folks attaching infra-red receivers to the Arduino boards and creating remote controlled lights. This involved making cunning use of TV remote controls specially purchased from Poundland (you'll never guess how much each one cost).
You can download the exercise from here if you fancy having a go.
Great fun for all, and a few new folks turned up, which was very nice. Hope to see you all at the next one.
