Description : Electromagnet GROVE http://www.seeedstudio.com/depot/Grove-Electromagnet-p-1820.html 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, due to Ampere's law(see drawing below). 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 easy to use, to learn electromagnet principle. Features Grove shape 1KG peak suction Low standby current Specification Working Voltage :DC 5V Working Current : 400mA Standby current : 200uA Load Weight: 1KG CODE: /* 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 }
