Using Arduino UNO GSM SIM800 SIM network to remotely control any Arduino with Blynk app. Share schematic + gerber file + BomList
Control an external LED light from anywhere in the world using the ESP8266. The GPIO pin serves as an output source to the LED.
Easy way to unlock and Lock door with Blynk app. Also, I will add code for to Lock & Unlock door by RFID and fingerprint sensor. 3 in 1.
In this project, I'm using a Kortex A1 IoT-sensor microcontroller in order to monitor temperature/humidity/pressure/altitude via WiFi.
Temboo is very easy to automate the IoT with Arduno YUN, in combination with Blynk and Dropbox to store pictures. All is free and easy.
Display information or variables on a LCD available at BLYNK app using IOT.
This guide shows you how to add Blynk Board support to the Arduino IDE.
