Edison is programmed using EdWare, an icon based graphical programming language. Programs are downloaded to Edison using the EdComm cable. The EdComm cable plugs into the computer's headphone jack and carries a pulsed audio signal to a high efficiency LED. The LED converts the pulsed audio signal into light that is received by Edison's line tracker phototransistor and loads the program into the processor.
Sensors and inputs
Obstacle detection: Infrared using 2 IR LEDs (front left and right) and IR receiver module (doubles as IR receiver)Remote control: IR receiver module (38kHz) Edison can learn IR codes from most standard TV/DVD remote controls
Infrared data comms: IR receiver module (double as obstacle detection sensor and IR remote receiver)
Line tracker: Red LED and phototransistor (doubles as barcode reader and programming port)
Light sensors: 2 phototransistors (front left and right)
Sound sensor: Piezo transducer (doubles as sounder)
Outputs
Drive: Differential drive systemInfrared data comms: 2 infrared LEDs (double as obstacle detection sensor)
Sound: Piezo buzzer (doubles as sound sensor)
Lights: 2 red LEDs (Front left and right)
