1. Introduction The Grove-Relay module is a digital normally-open switch. Through it, you can control circuit of high voltage with low voltage, say 5V on the controller. There is an indicator LED on the board, which will light up when the controlled terminals get closed.
2. Specifications Parameter v1.1 v1.2 Product Release Date 27th Jan 2013 9th June 2014 Operating Voltage 5V 3.
3. Usage 3.1 With TI LaunchPad Controlling other electronics (Relay) This example showcases how to use the Grove-relay module to control larger load, i.e. a desk lamp light. A 3V voltage signal can cause the relay to switch on, allowing current to flow through the connected appliance. /* Relay The basic Energia example. This example code is in the public domain.
delay(1000); // wait for a second } 3.2 With Arduino Below is a demo that shows you how to control a Grove - Relay with a Grove - Button. When the button gets pressed, the relay will close.
digitalWrite(6, LOW); } } 3.3 With Raspberry Pi This sample is show you how to use Grove - Relay by Raspberry Pi . The demo below will show that the relay be control by Grove -Button. # Raspberry Pi + Grove Switch + Grove Relay import time import grovepi # Connect the Grove Switch to digital port D3 # SIG,NC,VCC,GND switch = 3 # Connect the Grove Relay to digital port D4 # SIG,NC,VCC,GND relay = 4 grovepi.pinMode(switch,"INPUT") grovepi.pinMode(relay,"OUTPUT") while True: try: if grovepi.
grovepi.digitalWrite(relay,0) time.sleep(.05) except KeyboardInterrupt: grovepi.digitalWrite(relay,0) break except IOError: print "Error" 3.3.1 1. Run the program Find the path to the file(According to your own path) cd GrovePi/Software/Python/ 2. Run Program sudo python grove_switch_relay.
