Vma412 Adapter doesn't exists? What now?

Hello. Ive bought a VMA421 waterpump. I searched the Web and see that the POWERAdapter doesn’t exist anymore? What should i do? How can i connect the VMA421 to Arduino?

Hi @jhelbling,

The VMA421 has a working voltage range of 5 VDC to 12 VDC.
We have several adaptors on our website who can provide this voltage. We do recommend at least 5W.

You can use a mosfet module (VMA411) or motor drive board (VMA207) to control the pump via the Arduino.

Kind regards,

I’ve got the VMA207 Board,


How should i connect it to the VMA207?

Hi @jhelbling,

Have a look at the manual of the VMA207 https://www.velleman.eu/downloads/29/vma207_a4v01.pdf
You will need to download the library https://www.velleman.eu/downloads/29/vma207_afmotor.zip

Connect the shield like this

And use this code:
#include <AFMotor.h>

AF_DCMotor motor(3);    //number of motor (we use M3)

void setup() {
  Serial.begin(9600);           // set up Serial library at 9600 bps
  Serial.println("Motor test!");

  // turn on motor
  motor.setSpeed(200);
 
  motor.run(RELEASE);
}

void loop() {
  uint8_t i;
  
  Serial.print("tick");
  
  motor.run(FORWARD);
  for (i=0; i<255; i++) {
    motor.setSpeed(i);  
    delay(10);
 }
 
  for (i=255; i!=0; i--) {
    motor.setSpeed(i);  
    delay(10);
 }
  
  Serial.print("tock");

  motor.run(BACKWARD);
  for (i=0; i<255; i++) {
    motor.setSpeed(i);  
    delay(10);
 }
 
  for (i=255; i!=0; i--) {
    motor.setSpeed(i);  
    delay(10);
 }
  

  Serial.print("tech");
  motor.run(RELEASE);
  delay(1000);
}
