Work fast with our official CLI. The shield uses Arduino analog pins A4 and A5 for "I2C" serial communications with your sketch. You signed in with another tab or window. Open serial console at 38400bps, and, * send value "0" to reset all relays, or a channel number, * to activate that relay. $29.00. - Equiped with high-current relay, AC250V 10A ; DC30V 10A. Connect from 1 to 8 channels to your relays as required. As shown on the right, the R2 format uses analog inputs A4 and A5 for I2C connections, while the R3 format adds dedicated headers specifically for I2C near the top left of the board. ", EtherTen (100% Arduino compatible with onboard Ethernet), Zero Insertion Force (ZIF) Breakout for 28-Pin AVR. Furthermore, the I2C pins are located at D20 (SDA) and D21 (SCL) - not A4 and A5. The example sketch provides a very simplistic approach to controlling the relays, allowing one relay to be turned on at a time. 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. INPUT 5-24 Vdc +: Connect to the positive (+) lead of the power source for your relays. It communicates with your board using I2C, so you can even stack several shields together to drive 16, 24, or more outputs! Fitting a jumper in any position will set the matching address line HIGH, or logical 1. 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.

ELEGOO 8 Channel DC 5V Relay Module with Optocoupler for Arduino UNO R3 MEGA 2560 R3 Project 1280 DSP ARM PIC AVR STM32 Raspberry Pi. Connect from 1 to 8 channels to your relays as required. 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. To turn it off, use relay->off(1). No other pins on the Arduino are used by the shield other than power, so they are all available for connection to other devices in your projects. - Indication LED’s for Relay output status. The address lines 0, 1, and 2 are held LOW, or logical 0, by default on the shield. Place the jumper labelled "POWER INPUT CONNECT TO VIN", and connect an appropriate power supply to your Arduino. Any power you apply to the screw terminals will then be automatically sent through to the VIN input on the Arduino so that its onboard power supply can regulate it to 5V. Place the jumper labelled "POWER INPUT CONNECT TO VIN", and connect an appropriate DC power supply to suit your relays using the screw terminals marked "INPUT 5-24Vdc". OVERVIEW:The Relay Shield provides a solution for controlling high current devices that cannot be controlled by the Arduino’s Digital I/O pins due to their current and voltage limits.The Relay Shield features four high quality relays and provides NO/NC interfaces, four dynamic LED indicators to s The Grove - 8-Channel Solid State Relay is based on the high-quality G3MC202P module, which allows you to use a 5VDC to control MAX. Add to cart Copy and paste the sketch into the Arduino IDE. 3. Open the serial console in the Arduino IDE, make sure the speed is set to 38400, and type "0" then to turn off all relays or the number of a relay channel followed by to activate that relay. It is an 8-channel relay interface board, which can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, PLC, etc. Yay, What’s an Arduino. Yes, I2C.
