How do I run a 5V motor on Arduino?

Arduino Motor Control Setup

1. Connect 5V and ground of the IC to 5V and ground of Arduino.
2. Connect the motor to pins 2 and 3 of the IC.
3. Connect IN1 of the IC to pin 8 of Arduino.
4. Connect IN2 of the IC to pin 9 of Arduino.
5. Connect EN1 of IC to pin 2 of Arduino.
6. Connect SENS A pin of IC to the ground.

What does 2N2222 transistor do?

The 2N2222 is a common NPN bipolar junction transistor (BJT) used for general purpose low-power amplifying or switching applications. It is designed for low to medium current, low power, medium voltage, and can operate at moderately high speeds.

Why do DC motors need transistors?

Motor rated more than 5V can be driven with transistors as an another supply will provide the required power and control will be done through 5V PWM signal. It allow DC motors to run forwards or backwards as well as provide turn on/off functionality.

How much current can a 2N2222 transistor handle?

It’s a current controlled transistor. It has a Collector current of 800 mA. Power Dissipation of 2N2222 is 500mW. It can operate between -65 C to 200 C temperature.

How do you select a transistor in a circuit?

In choosing a suitable switching transistor:

1. The transistor’s maximum collector current must be greater than the load current.
2. The transistor’s maximum current gain must be at least 5 times the load current divided by the maximum output current from the IC.

How do transistors work Arduino?

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. Just like when using an LED, this limits the current flowing into the transistor through the base.

What do transistors do Arduino?

Your powerful friend, the transistor can control high-voltage motors and lights from a microcontroller pin.

How do I control the speed of the motor using Arduino?

The transistor acts like a switch, controlling the power of the motor. Arduino pin 3 is used to turn the transistor on and off and is given the name ‘motorPin’ in the sketch. When the program starts, it prompts you to give the values to control the speed of the motor. You need to enter a value between 0 and 255 in the Serial Monitor.

What is the function of transistor in Arduino?

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.

What types of motors can be used with Arduino boards?

In this chapter, we will interface different types of motors with the Arduino board (UNO) and show you how to connect the motor and drive it from your board. A DC motor (Direct Current motor) is the most common type of motor. DC motors normally have just two leads, one positive and one negative.

How to drive DCDC motor from Arduino board?

DC motors normally have just two leads, one positive and one negative. If you connect these two leads directly to a battery, the motor will rotate. If you switch the leads, the motor will rotate in the opposite direction. Warning − Do not drive the motor directly from Arduino board pins. This may damage the board. Use a driver Circuit or an IC.
