In this Lora project, I have shown how to make the LoRa Arduino ESP8266 control relay using the RYLR896 LoRa module with real-time feedback. So after turning on and off the appliances the receiver ...

Arduino Relay Driver Shield Circuit Diagram: In this 3-Channel Relay Driver Circuit, we have used an optocoupler to trigger the NPN transistor which further drives the relay. And optocoupler will be ...

The article is a tutorial on how to control 16 relay through Arduino microcontroller with Ethernet shield W5100. Hello, I'm going to share again with another project that helps many of you to solve ...

Here, pin D12 of Arduino is used to drive a standard 5mm LED, and D13 is used to drive an Electro-Magnetic Relay through a transistor-based relay driver. Everytime the tag values match, D13 goes high ...

I made this Arduino project that allows to turn ON and OFF LEDs using a cheap IR remote control as a preparation for the next big step: disassemble my girlfriend’s chinese LED lamp and replace its ...

Arduino has recently announced two new expansions to their Arduino Pro Opta PLC series – the Arduino Pro Opta Ext D1608E and Arduino Pro Opta Ext D1608S, the main difference between the two is that ...

I have connected water pump to Arduino via relay module which will control the pump as per Arduino’s command. Also, ... And when the sensor detects as water/ moisture level is above 500 it means there ...

I have used D4, D5, D6 & D7 pins to control the 4-channel relay module. As per the source code, when the control pins of the relay module receive the LOW signal the respective relay will turn on and ...
