ARDUINO: Motor DC con Transistor — MecatrnicaLATAM
So we connect it so that our motor, solenoid or light is connected to V+ but not ground (V-). Ground is connected to the transistor’s drain. When our arduino sends a HIGH signal to the transistor’s gate, it switches the transistor (connecting the drain and source) and completes the circuit for the motor, solenoid, or light.

Motor Speed Control with One Transistor - Arduino Project Hub
A small transistor like the PN2222 can be used as a switch that uses just a little current from the Arduino digital output to control the much bigger current of the motor. The transistor has three leads.
Lab: Using a Transistor to Control High Current Loads with
The transistor acts like a switch, controlling the power to the motor. Arduino pin 3 is used to turn the transistor on and off and is given the name 'motorPin' in the sketch. Result. Motor will spin in full speed when the Arduino pin number 3 goes high. Motor Speed Control. Following is the schematic diagram of a DC motor, connected to the
How to Control the Speed of a DC Motor with the Arduino
You can use the MotorControl sketch for the Arduino to put some input into a DC motor to give you full control of the motor on the fly. The MotorControl sketch. An Arduino Uno. A breadboard. A transistor. A DC motor. A diode. A 10k ohm variable resistor. A 2. 2k ohm resistor. Jump wires.

/9/2015You need the base current of the transistor to be about 1/10 th of the motor current to switch it on (saturate it) fully. So with 3 V supply the voltage across the base resistor is 3 - 0. 7 = 2. 3V. For 8 mA base current you need the resistor to be 2. 3/0. 008 = 287 ohms.
