Disconnect the motor from the Electronic Speed Controller (ESC) and wind it up with a . What is ESC, and why will we use it? Please help. Building something that flies like a quadcopter from scratch is possible, HOWEVER, if you are planning on writing your own flight controller you really should re-think. As we already know, BLDC motors require some kind of controller to function, which converts the DC voltage from the battery into a sequence of pulses applied in a specific order to the motor wires (phases). Answer (1 of 5): That's a significant requirement and will be impossible for a single Uno, or even two. because they have to frequently change the number of engine revolutions per minute to maneuver in the air. The 10k potentiometer is used to vary the speed of the BLDC motor, its output is connected to Arduino analog channel 0 (A0). But you probably don't want to try to build an ESC with a 2N2484). That is, in the Inrunner (most DC motors are designed according to this principle), the axis inside the motor rotates, and the shell remains stationary. Start turning the potentiometer knob gradually until the potentiometer output voltage is different than 0, and the sound will stop. Make sure that your BLDC motor is securely mounted. If you want a quad, buy a prebuilt flight controller like a Multiwii. So to solve this problem we use extra components called by Electronic Speed Controller (ESC).
