+[title] Motor control electronics
+[* black] The three parts of the controlling electronics are (from left to right in the first image): the charging port, the trigger mechanism, and the direction switch.
+[* black] The charging port (second image) charges the battery when a DC power supply is inserted into the connector. The port also lights up a red LED while charging.
+[* black] The trigger switch controls the speed of the motor by connecting more of the batteries to the motor as the trigger is depressed further.
+[* black] The direction switch controls the polarity of the voltage connected to the motor, which spins the motor either clockwise or counterclockwise.
