Délio Vicente at FABACADEMY 2014

Network and Communications:

On this week it was requested to design and build a wired or wireless network connecting at least two nodes.

Since time was not on my side this week I chose to fabricate the asynchronous network with two equal boards, one serving as bridge and other as node. After designing the standard board on Eagle program then added a 6female socket (so it can be added shields onto them later) and a 2pin header screw (to power them with a 9Vbattery) to both and mill it on the Modela.

Im now more agile on this mounting and soldering tiny electronic components, even if practice makes perfect, I have still a long way to go ;) Then using the previous fabISP programmer I just followed the always helpfull Providence tutorial on this and program each new PCB as node 0 and node 1. All went right using the fixed Neil code. Then connected both correctly and used serial monitor on Arduino IDE to send number node making all LED nodes light up once and twice the one on the node chosen. By suggestion of fabmaster Ferdi, I then applied a large red LED (with a 220v resistance soldered to ground pin) to make it light up as well.
