ARDUINO MEGA SHIELD PINOUT DRIVER

This is because the current requirements of most DC motors are too high for the Arduino’s pins and could damage them. Yes, you can connect a motor directly to an Arduino, but it is not recommended.

Once wired in correctly, simply turn on the switch on the board itself or press its enable button (if present) and your Arduino Motor Shield should be ready to go!Ĭan you connect motor directly to Arduino? Make sure that you use an appropriate voltage range as using too much or too little can damage both your motor shield and any motors connected to it. The shield itself has two screw terminals for connecting the positive and negative wires of the DC power source. To power your Arduino Motor Shield, you will need to connect it to a DC power supply that provides at least 12V and up to 24V. MotorOff(1) // turn off the second motor FAQ How do I power my Arduino Motor Shield? Note: this function also sets PWM value equal to zero of the selected motor MotorGo(0, CCW, 127) // turn on motor 1, counterclockwise, speed 50% Description of the motorOff() function Note: direction can be CW – clockwise, CCW – counterclockwise, BRAKEVCC – stop motor with interlock, BRAKEGND – stop motor without interlock. Parameters: motor number (0, 1), direction (CW, CCW, BRAKEVCC, BRAKEGND), PWM (0-255) set the corresponding values of the key B of the selected motor: if the motor direction is clockwise or sharp stop, set the corresponding values of key A of the selected motor: if motor direction is clockwise or smooth stop, if direct is the same as the directional value: Void motorGo(uint8_t motor, uint8_t direct, uint8_t pwm) MotorGo(1, BRAKEGND, 32) // stop motor 1 in mode 'off MotorGo(0, BRAKEVCC, 32) // bring motorGo(0, BRAKEVCC, 32) // bring motor 0 to the 'brake' mode switching the key state output to 'input' mode: convert the output of the state of motor keys 1 to the mode 'output': MotorGo(1, CCW, 127) // motorGo(1, CCW, 127) // motor 1 counterclockwise, PWM 50%ĭelay(3000) // wait 3 seconds, motors are turning PinMode(inBpin, OUTPUT) // outputs of B keys PinMode(inApin, OUTPUT) // outputs keys A transfer the control outputs to the 'output' mode #define CCW 2 //define CCW counterclockwise rotationĬonst uint8_t inApin = // define AB keys state outputs. #define BRAKEVCC 0 // determine the value of the sharp brake The speed is set by feeding the PWM signal, the fill factor of which is directly proportional to the speed.The direction in the motorGo() function is set by feeding the logic levels to A and B: A=LOW, B=HIGH – motor rotates one way A=HIGH, B=LOW – motor rotates the other way.Depending on the state of the keys the motor will rotate in one or the other direction. The second DC motor is controlled by outputs 4 (key A2), 9 (key B2) and 6 (PWM).The first DC motor is controlled via outputs 7 (key A1), 8 (key B1) and 5 (PWM).Monster Moto Shield is based on the VNH2SP30 chip, which allows you to control both speed and direction of the connected motors, as well as to block motors and read current consumption, using the analog pins of the Arduino.Ĭontrol of DC motors: The functions: motorGo (motor number, direction, PWM) and motorOff (motor number). The outputs of the Monster Moto Shield only work from an external 5.5 to 16V power supply, which must be connected to the Vin power inputs.
