DFR0017 Connecting to Arduino UNO
stevenmmarlow 2011-12-14 12:07:02 4916 Views2 Replies I have just purchased a DFR0017 relay module for use with an Arduino UNO. This device shipped with a header connector on the control side of the relay and a cable. The documentation does not give specific instructions for connection to the UNO, only info for connecting the load to switched. There is a six-pin (3x2) header near the AREF pin on the UNO board for which I am having difficulty finding documentation. Is that the ICSP1 header? Should I cut the female connector from the relay module cable for connection to the UNO or am I missing something?

The female connector is designed especially for the IO Expansion shield ([url=https://www.dfrobot.com/index.php?route=product/product&filter_name=dfr0088&product_id=264]DFR0088[/url]) If you do not own one of these shields, feel free to cut off the end of the cable, and just use it to insert directly into the Arduino female pins.
You might want to strip the cable a little and add some solder to make it stiffer.
Basically the pins are as follows:
Black=Ground -Should be plugged in to any of the 3 ground pins on the Arduino.
Red=Vcc (5V) -Should be plugged in to the 5V pin of the Arduino.
Green= Digital pin -Should be connected to any of Arduino's digital pins.
