Currency note counter is a machine that detects the notes of different denominations and tells its value. Here in this IoT project, we are using a color sensing technique to detect the note value.
ESP8266 is very popular for building IoT based Projects, but nowadays ESP32 is getting a lot of attention because of its BLE compatibility feature at a lowered cost.
The IoT industries introduced lots of technologies, but none of them was ideal for IoT devices, as they needed to transmit information to a long distance without using much power until the LoRa technology was introduced.
In this tutorial, we will make an ESP32 based Weather station in which we will build an ESP32 Webserver to display temperature, humidity, pressure, luminosity, and altitude values on a web browser.
According to a report there will be over 20.4 Billion connected things worldwide by 2020. IoT platforms are the main facilitators in the growth of connected devices.
Text to speech (TTS) has been used in many applications like voice assistants, announcements, ATMs etc. It is also used to help children in learning speaking and blind people in communication.
Do you know an internet time clock have a precision of 0.02 to 0.10 seconds? In this project we are going to make an ESP32 based internet clock to display the internet time over a 16x2 LCD display. The most used and popular protocol for synchronizing ti
