You could do something like using more relay boards with a shift register controlling each output. It can be controlled directly by Micro-controller ( Raspberry Pi, Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic). Here's an example of the bit in your code which switches everything off: void allOff() { // Declaring the function, for(int x = 2; x < 10; x++){ //turns off lights. void Rcounter(){ It is also elevated on some flower pots so it wont be in a puddle of water. allOff(); bacily instead of buying 8 outlets for 8 ports you only have to buy 4 outlets for the same amount of control. }, void WcounterOpp(){ A custom PCB project with an ESP8266 and 8-channel relay. Which means that the arduino can just power an led that in turn switches the relay closed or open(on or off). delay(time); Here we are not using any Relay Driver IC like ULN2003 and will only use an NPN transistor to control relay. That is why you should ground everything you possibly can. Then i cut it to about 3ft and connected the black wire (hot) to the common hot terminal block. RcounterOpp(); The Bluetooth module receives data from the paired Android smartwatch and triggers the relay based on the received data. There are also non-mechanical relays which don't make a clicking sound when closing the circuit. This 8 Channel Relay module can adopt most common range of microcontrollers, such as Arduino, Raspberry Pi, AVR, PIC, ARM with digital outputs to control larger loads devices like AC or DC Motors, Electromagnets, Soleniod, Incandescent light bulbs, Actuators and any another devices that you want to drive with in the relay. We use ESP8266-01 WiFi module for wireless comminication. delay(timeC); Leave it on if your using the arduino to power the board, if you were to use an external power supply you would remove it. allOff(); Relays are used where it is necessary to control a circuit by a separate low-power signal, or where several circuits must be controlled by one signal. ...

When connecting the arduino to the relay board sain smart uses optically isolated boards. Code // Arduino Relay Control Code . A relay can be used to control high voltages with a low voltage by connecting it to an MCU. Demonstration Video and complete code for Arduino Relay Control is given below. For demonstration purposes, let’s take a look at the pinout of a 2-channel relay module. Reply I tried to make it simple and doable. So you could get 4 of those and 8 shift registers, theres probably and easier way to do this but if your proficient in arduino … You will learn the meaning of lower trigger and high trigger. 5 years ago. pinMode(relay2, OUTPUT); Thanks! allOff(); allOff(); Incorrect or improper use could result in serious injury or death. Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid-state relays. allOff(); Reply Did you make this project? 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. AlternateColors(); I would love to see a YouTube of it in action. I was looking for a simple example of code and connection diagram to test my relay board. I ended up remaking the box with solid state relays. delay(timeC); delay(timeC); If we were to upload this code to the Arduino it will turn Relay #1 on for 1 second and then switch it off for 1 second and continue through this loop forever. delay(timeC); Wiring Bluetooth HC06 in 8 Channel Relay with Android & Arduino Microcontroller Another guide how to wire the HCo6 and 4 Channel Relay for switching, The HC06 modules uses BlueCore is a single chip radio and baseband IC for Bluetooth 2.4GHz system including enhance data rates (EDR) to 3Mbps. delay(timef); This was a simple extension chord that i found in Meijer. This video shows how to control 16 AC or DC load using the 16 Channel Relay and Arduino. }, void RcounterOpp(){ Using a relay module with a different number of channels is similar. To connect all the hot wires together I used a terminal block which made it easy. The 10 pins in the middle of the board connect to the board as follows: To power the arduino use a usb cord and a phone adapter. arduino 8 channel relay module w/ ps/2 keyboard controller. pinMode(relay3, OUTPUT); Anand October 23, 2019 . delay(timeC); Which means that the arduino can just power an led that in turn switches the relay closed or open(on or off). int PIRInterrupt = 2; // Timer Variables long lastDebounceTime = 0; long debounceDelay = 10000; void setup() { // Pin for relay module set as output pinMode(relay, OUTPUT); digitalWrite(relay, HIGH); // PIR motion sensor set as an input … Download the schematic and Arduino .ino code from the link below: https://drive.google.com/drive/u/0/folders/0B8lboyisdqhBU0EtdEl3RExGdmc. allOff(); I used mechanical relays for my light display one year (so I could run more power through a preprogrammed box). allOff(); There is a tab on the hot and neutral sides of the outlet.
