FtSwarmLamp

With this class fischertechnik lamps and LEDs can be operated at the outputs M1 and M2. Use class FtSwarmPixel to run RGB-LEDs or ftPixels.

several LEDs and lamps

If an LED is connected to a motor output with both cables, the polarity must be tested. If the LED does not light up, reverse the connections to the LED.

With the fischertechnik TX and TXT controllers the outputs can be extended to eight independent ports (O1..O8). This is only conditionally possible with the ftSwarm controllers. Two LEDs can be switched to GND at M1 or M2. These can be switched on alternately but not simultaneously. In this case use one instance of the class FtSwarmMotor for both LEDs. setSpeed(255) switches on one of the two LEDs, setSpeed(-255) the other LED. setSpeed(0) turns off both LEDs.

FtSwarmLamp(FtSwarmSerialNumber_t serialNumber, FtSwarmPort_t port)

Constructor to create a FtSwarmLamp object. If the referenced controller isn’t connected to the swarm yet, the firmware will waits until the controller gets online.

• serialNumber: Serial number of the used ftSwarm controller.
• port: FTSWARM_M1 or FTSWARM_M2

FtSwarmLamp( const char *name )

Constructor to create a FtSwarmLamp object. If the referenced controller isn’t connected to the swarm yet, the firmware will waits until the controller gets online.

• name: Alias name of the IO port.

void on( uint8_t power = 255 )

This function set the lamp or LED “on”. Brightness could be specified optionally..

void off( void )

Set the lamp or LED off. Same as on(0).
