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

4.2 With Raspberry Pi

1. You should have got a raspberry pi and a grovepi or grovepi+.

2. You should have completed configuring the development environment, otherwise follow here.

3. Connection. Plug the sensor to grovepi socket D4 by using a grove cable.

4. Navigate to the demos' directory:

cd yourpath/GrovePi/Software/Python/

To see the code

nano grove_electromagnet.py # "Ctrl+x" to exit #

import time

import grovepi

# The electromagnet can hold a 1KG weight

# Connect the Grove Electromagnet to digital port D4

# SIG,NC,VCC,GND

electromagnet = 4

grovepi.pinMode(electromagnet,"OUTPUT")

time.sleep(1)

while True:

try:

# Switch on electromagnet

grovepi.digitalWrite(electromagnet,1)

print "on"

time.sleep(2)

# Switch off electromagnet
