Taking a break

 We're taking a break moving shop and hope to be back soon. We hope to start shipping orders in Nov 2018. 

An electromagnet is a type of magnet in which the magnetic field is produced by electric current. An electric current flowing in a wire creates a magnetic field around the wire. To concentrate the magnetic field, in an electromagnet the wire is wound into a coil with many turns of wire lying side by side. The magnetic field of all the turns of wire passes through the center of the coil, creating a strong magnetic field there. Grove - Electromagnet can shuck 1KG weight and hold on. It is easy to use, and to learn the electromagnet principle.


  • Grove shape
  • 1kg peak suction
  • Low standby current


  • Working Voltage: 5V DC
  • Working Current: 400mA
  • Standby current: 200uA
  • Load Weight: 1kg


  Turns on an Electromagnet on for one second, then off for one second, repeatedly.

  This example code is in the public domain.

int Electromagnet = 0;
int LED = 13;

// the setup routine runs once when you press reset:
void setup() {                
  // initialize the digital pin as an output.
  pinMode(Electromagnet, OUTPUT); 
  pinMode(LED, OUTPUT);   

// the loop routine runs over and over again forever:
void loop() {
  digitalWrite(Electromagnet, HIGH); // turn the Electromagnet on (HIGH is the voltage level)
  digitalWrite(LED, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);               // wait for a second
  digitalWrite(Electromagnet, LOW);// turn the Electromagnet off by making the voltage LOW
  digitalWrite(LED, LOW);  // turn the LED off by making the voltage LOW
  delay(1000);               // wait for a second
