Arduino Basics: Relay Module
Channel Mini easy to use Relay shield for Arduino Nano consists of ULN2003 IC and 2 Mini 12V Relays with NO/NC contacts of 2A-24V Load Capacity. ULN2003 used as Relay coil driver. Relay can be controlled from D3 and D4 of Arduino Nano.
Arduino Uno Motor control using 2 Relays, 2 Limit switches
Arduino 2 Channel Relay: This instructable is for connecting your Arduino to a 2 Channel relay module and using your sketch to control the switches. I bought the 2 Relay Module on eBay (for $9. 50) to drive a couple of 240V parts (a vacuum cleaner and a rotary engraving too. . .
Arduino DC Motor Speed and Direction Control using Relays
The further detail about 2 relay module interfacing with Arduino will be given later in this tutorial. 2 Relay Module Interfacing with Arduino. 2 Relay Module is an electronic device consists of two relays as its major components. Relay is a switch which makes or loses the connection between two different circuits.

TRR-1A relays and COTO TECHNOLOGY – 8L01-05-001 only require 10mA each so you can easily drive 8 or more of these relays from an Arduino board supplied by a USB 500mA power supply plugged into the USB connector (The Arduino Uno has 500mA resetable fuse on the USB input).
Connecting a Relay to Arduino - Make
For security reasons, the sketch checks the number of the sender and this information must be stored in the arduino_secrets. h file. We don't know the status of the relays and therefore the sketch uses a approach, where each SMS received with 1 or 2 as text toggles the status of the corresponding relays.
Arduino 4 Relays Shield
/12/2012 2 relays with delays. Sep 10, 2012, 10:38 am. Hi guys im in urgent need of putting together code for an arduino duemilanove to control two relays. One relay needs two continually run when it is started by a push button and then the sequence will begin, start
Power Relays, Over 2 Amps - Relays - DigiKey
- Arduino makes blinking the Digital Outputs connected to the relays, in order to test if they all work properly. In my case, one relay is damaged. 3-Once the Bluetooth connection is established between the Android tablet and the HC-06 module, the program waits to receive messages.
