How to Make (Almost) Anything

MAS 863 2010
Week 12 assignment: - build a network with at least two nodes

for this week, I am using Neil’s hello board which has 3 nodes that communicate with the computer.

i milled the circuit boards and then soldered the components as usual. the codes were changed a little so that when a digit between 0 and 2 is pressed, an LED will blink which corresponds to the number pressed on the keyboard. the nodes were given ID numbers 0, 1 and 2. at the same time, in the serial terminal, the name of the node is displayed as well.

below is an image of the 3 boards I made.
