As an example for this Arduino Relay Tutorial we will use the HL-52S 2 channel relay module, which has 2 relays with rating of 10A @ 250 and 125 V AC and 10A @ 30 and 28 V DC. The high voltage output connector has 3 pins, the middle one is the common pin and as we can see ...
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 server We...

Arduino模块4路MOSFET切换器说明书 ARDUINO MODULE 4CH MOSFET SWITCH User Manual Overview:MOSFET is an electronic devices with good switching characteristics. It is widely used in circuits, such as power supplies switching, motor drives, lighting dimmer and so on. Relay is another kind of module ...
Upload the code to your Arduino uno board. This is done to tell the DS3231 module to start the date and time from the above-set date and time. Now, again you have to comment on that time setup line because if you are not doing so every time you interrupt the power supply the date...
Using encoding schemes reduces the specification of an IR code to a bitstream / hex value, which is LSB by default and pulse / pause timings of header, 0, and 1. The hex value is quite readable. These schemes can not put any semantics like address, command or checksum on this bitstream...

on the Xboard (Spkr or LED or both) or on the webserver (blinking text). */ Once the code has finished uploading you can plugin Xbee and relay. The relay has been set to digital pin 2 on the Arduinoso please hook up the relay’s data pin to pin 2 on the Arduino or modify...
