Blynk app is an easy to use Android and IOS based application, helps in controlling Arduino, Raspberry Pi and others for the purpose of IoT.

Previously we covered a tutorial to use ThingSpeak IoT Cloud with ESP32, today in this tutorial we will use another popular IoT application “Blynk” to control LED us

IFTTT (If This Then That) is a free IoT service that allows you to send a trigger from one device, and allow that trigger to make something happen elsewhere.

Blynk is an IoT Platform to control Arduino, Raspberry Pi, NodeMCU and other microcontrollers over the Internet. Blynk app is a digital dashboard where you can build a graphic interface for any IoT based project by simply dragging and dropping widgets.

ESP series WiFi modules have become very popular among hobbyists and industries for IoT based projects.

ESP32 is the powerful tool for IoT applications having inbuilt Bluetooth, temperature senso, hall sensor etc.

In previous project, we learned about sending data to IoT platform ThingSpeak using Raspberry pi.

ESP32 is a great development board for the IoT applications as it is low cost, low power consumption and has many powerful features. ESP32 can be programmed in various Environments like Arduino IDE, Espressif-IDF, MicroPython, Lua etc.

ESP32 is a powerful development tool for the prototyping of IoT application as it has inbuilt Bluetooth, Wi-Fi and features of a powerful microcontroller. For more details about ESP32 and its features you can refer previous articles of ESP32.

ESP32 is an important invention for the applications of IoT as it is used for various IoT purposes and has inbuilt Bluetooth, Wi-Fi and capabilities of a microcontroller. For more details about ESP32 and its features you can refer previous articles of ESP32.
