Connection Connect ESP8266 GPIO2 pin to 5V relay module IN. Because relay module operats on 5V andESP8266operate on 3.3V we will use 2N2222 NPN transistor to shift levels. Grund is common for 5v and 3.3V. On relay we can connect different devices. EasyIoT server configuration In EasyIoT...
The standardized shield form factor enables a smooth connection with Arduino and compatibles. The shield also has four LED indicators to show the on/off state of each relay. Relays are useful in switching on/off AC appliances like fan, light, motor or high current DC actuators like solenoid ...
with a clear power indicator and relay status indicator to keep you informed of the module's status. The blue KF301 terminals offer a convenient connection point for the control lines, simplifying the setup process. The module's compact size and lightweight design make it easy to install in ...
(Normally Closed) interface. It could be a nice solution for controlling devices that could not be directly controlled by Arduino's Digital I/Os. The standardized shield form factor enables a smooth connection with Arduino and compatibles. The shield also has four LED indicators to show the on...
The shield has 4 buttons (S1-S4), so that a connection test is also possible without uploaded sketch. With the help of Power DC adapters, I have connected a Y-cable to both the Arduino and Relay1. In my setup I use the green terminal adapters COM1 and NO1, respectively the plus po...

power. It really is a coil inside the relay: Powering the coil creates a magnetic field inside the relay, 'creates' a magnet if you will, that attracts a metal pin inside the relay enclosure, which in turn touches one of two tiny contacts (on and off) and creates a connection between...
The ESP8266 WiFi Connection manager with web captive portal, this Arduino library can make configure AP’s SSID and password via web page when you want LinkNode R4 to connect to AP. Open Arduino IDE and go toSketch –> Include Library –> Manage Libraries ...
Unfortunately, I am not sure how to approach splitting my mains 240V into 4 different inputs. All I can think now is to use a metal plate, solder the mains to the metal plate, and solder to the live connection of the 4 inputs to that plate. Then do the same for neutral and ...
