Notes from TinkerIt course by Matt Bidulph

I'm rapidly approaching the end of the daybook I was using when I went to #DConstruct09. The following notes need to be transferred out to somewhere more findable before the book goes on the pile of full notebooks, though they won't make much sense unless you have Daniel and Matt's course notes for the afternoon session, I'm afraid.

When using the Zigbee radio shields Daniel supplied, you need to choose XB2NET 2.5 CO-ORDINATOR from the drop down menu and select ZIGBEE ROUTER/END DEV as the device type. The PAD ID should default to 234. You may need to choose 1220 (I circled in in the notes) and you should choose a nodeId of something like "Jerry".

In terms of optocouplers, look at the 4025. And use a back EMF protection diode if your circuit has a motor or inductive coil in it. The silver stripe on the diode must be on the positive side of the circuit!
