This board brings out the A0-A5 pins to a row of headers that also provide separate power and ground points for each A0-A5 pin. Servo motors are 3 wire devices. The Motor shield can be powered directly from Arduino or from external power source. D10 controls speed of motor A and D11 controls speed of motor B. The pin spacing is also 2mm rather than the standard 2. Drive 2 DC motors at 4.

This pin is available for other use if not using it to drive a servo motor. Servos are typically used to turn a small steering ll298p or to rotate a sensor, such as an ultrasonic rangefinder for obstacle avoidance. Below is an example code, you can copy and paste it on Arduino IDE. The LP contains two full H-Bridge drive channels that provide full speed and moto control.

This board brings out the A0-A5 pins to a row of headers that also provide separate power and ground points for each A0-A5 pin. Use mirror motor to drive DRI to aviod the conflicts. For this 5V regulator to function, the VMS voltage must be at least 6. This arduino motor shield can be directly mounted onto standard Arduino Uno and Arduino Mega. If you have the OPT jumper in place and power coming on the DC Jack on the Arduino, it will work but the DC motor noise will be coupled into the 5V logic power supply and may cause eradicate behavior and so it is not really recommended.
The other Bluetooth header is a pin male header. Onboard also comes with through-hole pad, so you are able to weld the electronic ,298p to design a variety of prototyping circuits. The maximum voltage supply is DC 18V. D11 is for controlling the speed of motor B, and D13 is l2998p controlling the direction.
These work by sending out a ping of ultrasonic sound and timing how long it takes for the ping to come back. The shield uses the following pins which remain available if you are not using that function: DC MotorServoShield.
D10 controls speed of motor A and D11 controls speed of motor B. Motir VMS is the positive motor voltage which can range from 4.
Depending on the motor of choice, you can make it fast or handle a higher payload. This page was last edited on 14 Septemberat This ensures that they have good clean 5V power independent of mptor the motors are doing. Logic Power subsystem The Arduino 5V is brought up to the shield and is available on the 6 sets of red sensor 5V pins, the yellow Ping connector for Ultrasonic Rangefinders and the 2 blue digital notor.

D4 D5 D6 D7. Pin 4,5,6,7 are used to drive two DC motor. To use this option, the motor power input must be at least 6. Pin 12 controls direction of motor A and Pin 13 controls direction of motor B.
This type of connector is compatible with HC Bluetooth modules and perhaps some others.
The 2 DC motor drive channels can operate at voltages from 4. This 5V feeds the white servo connector. These motor connection points are also mirrored on a 4-pin female notor for a little more flexibility.
2x2A DC Motor Shield for Arduino
The white headers are the signal lines, the red headers provide 5V and the black headers provide ground. Servo motors are 3 wire devices. Drive 2 DC motors at 4. Drive 1 servo motor with a dedicated 5V regulated power. Views Read View source View history.
