Have you ever thought of controlling your Arduino board remotely without using any shield or module like ESP8266, Bluetooth? Yes, it is possible with the help of Blynk App and its server. Blynk is a very popular IoT platform to build IoT projects like:

• IoT Controlled LED using Blynk and ESP8266 (Node MCU)
• IoT based Temperature and Humidity Monitoring using BLYNK, ESP8266 and DHT11 Sensor
• IoT Home Automation using Blynk App using ESP32
• IoT based Home Automation using Blynk App and Raspberry Pi
• IoT Controlled LED using ESP32 with Blynk App

 

Here in this project we will control two LEDs remotely using Blynk app. Both the LEDs will be connected with Arduino, one LED will be made on and off, and another LED’s brightness will be controlled using Blynk App.
