One of the most useful things you can do with an arduino buy it on amazon ebay is control higher voltage 120 240v devices like fans lights heaters and other household appliancessince the arduino operates at 5v it cant control these higher voltage devices directly but you can use a 5v relay to switch the 120 240v current and use the arduino to control the relay. The digital inputs and relay outputs are equipped with an led that indicates the status.
8 Channel Relay Board For Arduino And Pic Microcontroller
Relay shield 1 gnd pin is connected to relay shield 2 gnd pin.
Arduino relais shield schaltplan.
Do not operate voltage more than 35v dc.
This will prevent the relay shield from making contact.
It looks like the shield is just if you put the pin on the relay turns on so the blink example with pins 4 5 6 or 7 instead of 13 will turn the relays on and off.
Shield to control 6 relay 6 digital input and 6 analog input with arduino duemilanove arduino uno.
Standardized shield form factor enables smoothly connection with the arduino.
Find these and other hardware projects on arduino project hub.
The arduino 4 relays shield is a solution for driving high power loads that cannot be controlled by arduinos digital ios due to the current and voltage limits of the controller.
The relay shield provides four high quality relay that can control high current loads to arduino seeeduino boards.
It also provides no normally open nc normally closed interface.
The shield also has four dynamic indicators show the onoff state of each relay.
Explore 36 projects tagged with relay.
Try out the blink example.
The circuit diagram is very simple.
Place 2 layers of electrical tape on the top of thearduinos usb connector.
The shield features four relays each relay provides 2 pole changeover contacts no and nc.
In order to increase the current limit of each output the 2 changeover contacts have been put in parallel.
2connect another relay shield lets call this one relay shield 2 using jumper cableswires to relay shield 1 as shown in the figure below.
Guide for relay module with arduino this article shows how to control mains voltage with the arduino using a relay module.
Simple relay shield for arduino.
It could be a nice solution for controlling devices that could not be directly controlled by arduinos digital ios.
1stack one of the relay shields lets call this one relay shield 1 onto the arduino development board.
We make a brief introduction to the relay module and build a simple project example with the arduino.
