Cavern Remote user guide

Setting up

Ambient lighting control is using the Firmata protocol. Use a board on a serial port that supports Firmata, Arduino is one of them. In case of any Arduino, a StandardFirmata example should be loaded on the target. All configuration is in web\_cavern.js, including the port and the controlled pins. Cavern Remote only controls 2 relays with 2 ports or 4 relays with pairs in parallel. The wiring guide is:

• The relayPowerRed and relayGreenBlue pins should connect to the Vcc pins of +12V/red and green/blue relays' respectively. If you use single relays, split the Vcc between both enable pins.
• Wire the R/G/B relays to NO and +12V to NC.
• JDVcc should be supplied from a different source than the Vcc pins for current distribution. Ground distribution should also be considered between all ground pins of the Arduino.
• The other pin variables set the signal pins which control each relay (active high). Also set and check the COM port.
