Description This is a phototropic beam robot. It can sense the brightness of light with three light dependant resistors (LDRs), which feedback signals to the circuit to control two motors and two LEDs.By changing how the motors are connected, the robot can go towards the light(photovore) or avoid light(photophobe). Two small variable resistors on the PCB allow you to adjust the speed of the robot and the level of light required to turn on the LEDs. Packaging Each kit comes in a colour printed box with manuals on CD. Box is printed in Chinese. English box is producing now. E-mail a friend about this item. |
