Laser Sensor Power Source Circuit
DESCRIPTION
This circuit provides power to the laser sensor. The laser sensor emits radio
waves towards an object in
front and measures the distance and direction of the object by receiving the
beam reflections. Based on
the reflections, the sensor calculates the difference in speed between t ...
