In our previous tutorial, we have created a Home Automation using NodeMCU and Blynk. Using Blynk, we can control the devices anywhere in the World. We connected our NodeMCU with an optocoupler based relay and programmed it with Blynk code. Actually, it's very simple and no programming knowledge is required.Now in this tutorial, we will add an additional feature...
NodeMCU is very popular in Home Automation. It's WiFi capabilities and Arduino IDE support making it easier for IoT Applications. It is very tiny and has many Digital I/O pins, Serial Communication and I2C Communication. NodeMCU has a micro USB port to program it using your existing mobile cable (no additional programmer needed). There is a successor called ESP32 Development board...
Blynk is an IoT platform with drag and drop mobile Application. It is an Open-Source Cloud IoT platform to control appliances and monitor sensor data from anywhere in the World. You just need to upload the standard Blynk Program into it (No Coding skills needed) and rest is done by the App itself. This makes the IoT applications with...
