Arduino relay shield how to#
This instructable is also online at How to Add Relays to Arduino The pfodDesigner generates all the Arduino code you need for your custom menus and the pfodApp takes care of displaying the menus on your mobile and handling your selections.

No Android programming and no Arduino coding.

If you are looking for a simple way to switch these relays on and off from your Android mobile, via bluetooth, wifi or SMS, with optional 128 bit security, check out pfodDesigner ( and this instructable Code generator for custom Android/Arduino menus to switch Arduino outputs on and off Absolutely NO programming required. ESP8266-01 8) ESP-01 Relay Module 9) FET Sheilds 10) Solid State Relays Finally there small section on Help My Relay Stopped Working (RC Snubbers) 4) Separate multi-relay 5V modules high triggered and low triggered 5) Separate multi-relay 12V modules high triggered and low triggered 6) Modifications for Driving a 5V relay module from a 3.3V Arduino board 7) High/Low Triggered Relays for Use with 3.3V boards, e.g. We will look at a number of configurations for connecting relay modules to Arduino boards:-ġ) Direct driven reed relays 2) Single 5V power relays powered from the Arduino board's 5V supply 3) Four (4) relay shields using a separate supply. When you are selecting a relay to connect to your Arduino you need to considerĪ) the power (voltage and current) of what you want to switch on and off and b) the power (voltage and current) required to drive the relay (i.e. How to select Relays – Its all about Power.
See Bluetooth Low Energy (BLE) made simple with pfodApp.Īnother simple solution for on/off Home Automation is to use pfodDesignerV3 to design your control for upto 4 switches and then use a Arduino Uno + Cheap/Simple Wifi Shield + DFROBOT Relay Shield for Arduino V2.1 powered by a USB power supply and controlled by pfodApp and, if switching mains power, have an electrician wire it in. BLE is more difficult to use but pfoddesignerV3 and pfodApp makes it easy. Classic Bluetooth shields have been replaced by BLE shields/boards. Update: 19th Dec 2021 – marked up a number of product links as “no longer available”.
Arduino relay shield zip file#
The library is an installable ZIP file for the Arduino IDE and includes two demo sketches to show its function.ĭownload CANADUINO® I2C Relay Library (incl.Update: 5th Jan 2022 – Added ESP-01 Relay Module We designed a library for Arduino which makes it very easy to address every single relay in a stack of up to 8 modules (max. Unfortunately, the design flaws of Arduino UNO and MEGA boards make it impossible to use “stock” spacers in all four corners. We include a set of short and long Nylon spacers (M3) that can easily be modified (cut) to fit. UNO, MEGA, Leonardo), or by an external 5V source connected to the screw terminal if it is a 3.3V Arduino module (e.g. The relay modules are powered by the 5V line available on every 5V Arduino module (e.g. The relays have normally open (NO) and normally closed (NC) contacts to drive loads up to 750VA or larger contactors for even higher switching capacities. The relays can switch loads up to 3A 250VAC per relay output. It communicates with any compatible 3.3V and 5V Arduino module through its I2C interface and only requires the two I2C signals to address up to 64 relays.
CANADUINO® Stackable I2C Relay Shield for Arduino is available as assembled and tested module or as a DIY soldering kit with all SMD parts already assembled.
