Option 3: Pass power from Arduino power supply to relays. The 8-Channel Relay Driver Shield makes it simple and convenient to drive up to 8 loads such as 12V relays from just 2 pins of your Arduino compatible board or other microcontroller. In this option the power supply for the Arduino and the power supply for the relays are kept separate, so you need two power supplies: one for the Arduino, one for the relays. Furthermore, the I2C pins are located at D20 (SDA) and D21 (SCL) - not A4 and A5. boards, displays and modules for arduino, * Example sketch to control the RELAY8 8-Channel Relay, * Driver Shield. To activate multiple relays, add the values of those relays together. There are several options for supplying power to the relays connected to the shield, depending on the settings of the jumper labelled "POWER INPUT CONNECT TO VIN" and where you connect your power supply. This makes it easy to understand and will help you get started with your own projects, but a more complete solution would use a single byte to represent the current state of the outputs and then apply "bitwise operators" to turn individual relays on or off without altering the state of any other relay. If you're only going to use your shield with a Mega-style board, snip off the A4 and A5 pins from the shield and run jumper wires over from shield A4 to D20 and shield A5 to D21. Be careful when tinkering. It is possible to control the Relay shield through Arduino/DFRduino using digital IOs with external 7 to 12V supply. #include "RelayShield.h". Each relay channel therefore has the following corresponding value: To activate one specific relay, send the value that corresponds to that relay: to turn on relay 5, send the value "16". Instantiate the library with RelayShield* relay = new RelayShield(); To turn a relay 1 on, use relay->on(1) Then, use a soldering iron and solder to make solder bridges joining each of the middle pads to the pad above it. 1. Three-pin Header Connector CN1 and CN2 provided to connect the Load. The I2C communications bus used to control the 8-Channel Relay Driver Shield allows multiple devices to share the same connections. Work fast with our official CLI. By default it comes configured to suit R2 headers, which means that for almost all current models except the Arduino Leonardo you can plug the shield in without any changes and it will work just fine. It communicates with your board using I2C, so you can even stack several shields together to drive 16, 24, or more outputs! Note that with this option you must be careful to use a power supply that matches the limits of the Arduino, so a supply of around 7V to 9Vdc is recommended. This Relay Shield for Arduino acts like a switch. You do not need to do that when using the 8-Channel Relay Driver Shield, because the protection diodes are built in to the shield itself.
