The only pin Bluetooth connectors are generally associated with automobiles, so this connector does not seem to be of much use. Drive 2 DC motors at 4. Navigation menu Personal tools Log in. The motor power comes in on the 2-pos screw terminal. DC Motor , Servo , Shield.

Motor drive using pins.
D10 controls speed of motor A and D11 controls speed of motor B. Servos are typically used to turn a small steering wheel or to rotate a sensor, such as an l29p8 rangefinder for obstacle avoidance. It is also used to power the logic portion of the LP chip.
L298P Motor Driver Shield
Reducing the speed control pins to a PWM value of zero will get things stopped. In addition, many of these pins are broken out to other headers for easy hookup. Controllers such as Mega with full port expansion. Ultrasonic Range Finder Ping connector. Usually there are 2 pins motlr to determine the direction of rotation for each motor, but this shield has an inverter that provides an inverted version of the signal to the two pins.
This isolates any servo electrical noise from getting back into the main 5V that l98p the logic.
The motor power comes in on the 2-pos screw terminal. The LP contains two full H-Bridge drive channels motoe provide full speed and direction control.
This arduino motor shield is ideal for building Arduino robot or other Arduino motor control projects.

The program below runs the DC motor control portion through a sequence of events. Navigation Main page Random page Recent changes Help.
Drive 1 servo motor with a dedicated 5V regulated power. Reviews There are no reviews yet. This motor power is fed to a 5V regulator that is mounted to the bottom of the shield.
Arduino 9 Axes Motion Shield. Pin 12 controls direction of motor A and Pin 13 controls direction of motor B. The board has a dedicated 4-pin header to connect the sensor.
This ensures that they have good clean 5V power independent of what the motors are doing. These work by sending out a ping of ultrasonic sound and timing how long it takes for the ping to come back. When DIY your robot, it is necessary to use the motor driver board to drive the DC motors, however, sometimes need to connect the motor drive board to UNO using lots of jumper wires, pretty inconvenient.

The Motor shield can be powered directly from Arduino or from external power source. 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.
Onboard also comes with through-hole pad, so you are able to weld the electronic elements to design a variety of prototyping circuits. This 5V feeds the white servo connector. 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 connectors.

The other Bluetooth header is a pin male header. Stacking female connectors for supporting another daughter card. This page was last edited on 14 Septemberat The white headers are the signal lines, the red headers provide 5V and the black headers provide ground. 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 connectors.
It is strongly encouraged to use external power supply to power the motor shield.
