The sciBot project uses RCA plugs and jacks as the standard connector for sensors, actuators, and accessories. The mBot has four RJ25 jacks, with the jack number written on the top of the mBot. Unfortunately, the mBot does not come with RCA jacks, so we must make an adaptor that connects RCA jacks to a RJ14 plug that can connect to the mBot.
|Centre Pin Connection (depends on port)
|Port 1||Port 2||Port 3||Port 4|
On our adaptor, every red jack has a centre pin with +5V, and an outer shield that is connected to ground.
Every white jack has an outer shield that is connected to ground, and a centre pin that is connected to an Arduino analog or digital pin (A0, A2, 9, or 11).
The RJ14 jack (registered jack 14) has 4 conductors, and was designed to be used for phones that have 2 landlines.
