Connecting the MarcDuino Master Board

Connecting the MarcDuino master (dome panel & sound) board

The master board connects to the receiver and 10 panel servos.

For connecting the second slave MarcDuino board (HP servo and display) board, see this page.

You'll need a XBee breakout board like this one, which will hold a traditional XBee receiver or a Wifly receiver (the latter one to use with the iPhone App).

Additionally, you can hook up my MP3Trigger sound system or my CF-III sound system, or an alternate sound system that responds to the same sound command language. You can also optionnaly connect an RC receiver channel to take advantage of the RC control mode.

The fully connected MarcDuino Panel Controller board looks like the picture below. See more details and a video on how to setup and connect the MP3Trigger board here.

Here is the alternate setup if using the CF-III sound setup. Note that the newer CF-III units have changed the connector, so the gender adapter is no longer needed. However you'll need to install headers and cut a trace on the newer boards, as explained here.

I like to use these jumper cables to wire boards together:

3-prong to 3 prong male/male servo extensions:

When you need only one wire or just any other number than three (like for connecting to the WiFly), these are perfect, just peel away the number of wires you need:

For power I use these:

Finally, if your servo leads are too short and you need an extension, try these:

The 10 dome servos should be connected to their respective panels in the same order as they appear on the R2Touch App:

The orientation of the servos in the dome is important. To use the MarcDuino Panel Controller code without modifications, the servos should be oriented this way, so that panels all open with the servos going in the same direction. Mechanical linkages should be adjusted so that panels are closed with a stick full down (1000 ms pulses), and fully open with a stick full up (2000 ms) when under RC control.
