Learn more. The Arduino 4 Relays Shield is a solution for driving high power loads that cannot be controlled by Arduino's digital IOs, due to the current and voltage limits of the controller. 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 are using a Freetronics EtherMega board - you must apply power to the shield via the terminal block. Previously we have built 4-channel Relay Driver Module, but this time we are building this relay module as Arduino Shield, so that you just have to fix it over Arduino and it will be ready to use.Relays are useful for triggering home AC appliances with low signal and they are used in Home Automation Systems.. Leave the jumper labelled "POWER INPUT CONNECT TO VIN" off the board, and connect an appropriate DC power supply to suit your relays using the screw terminals marked "INPUT 5-24Vdc". Most R3 Arduino boards simply link the new I2C headers directly to A4 and A5 so that they can also work with R2 shields without any changes at all. All possible addresses are shown in the table below. If you don't want to modify your board, just bend the pins out so they don't slot into the 'Mega A4/A5 sockets. A simple library for controlling the Freetronics 8-Channel Relay Driver Shield http://tron.cc/r8 - johnservinis/arduino-relay-shield Yes, it did., So instead Arduinos.
