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...
Home automation is very popular nowadays. A lot of people is interested in automating their homes. There are few things to be noted before implementing in your existing switchboard, a few logical problems may arise like, The Switch can’t able to turn OFF the device until you Turn it OFF with Remote (in case of Parallel connections) or the remote...
