You mostly have seen Data logging web server with real-time graphs and tables on ThingSpeak and other IoT platforms.

Raspberry Pi 4 is the improved version of Raspberry Pi 3 B+. Raspberry Pi 4 comes with Cortex-A72 quad-core processor running at 1.5GHz with memory bumped up to the LPDDR4. It has three times better processing performance and speed than the Raspberry Pi 3.

There are many kinds of Wi-Fi door lock available in the market which makes your home more secure and saves time in finding the keys. We previously built a smartphon

We all have waited in a queue for payment in shopping malls and other places, its very tiring and wastes a lot of time in the billing process.

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.

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.

Servos are commonly used motors in Robotics. Interfacing and the controlling Servo motor with microcontrollers like Arduino, Raspberry Pi, and NodeMCU are very easy.

Stepper motor is a type of brushless DC motor whose rotation is divided into steps per revolution. Stepper motor takes a distinct number of steps to complete a one 360° rotation.

Previously we built a Wi-Fi controlled robot using NodeMCU, this time we are attaching a camera with the robot to make it a surveillance robot car.

Previously we built an IoT based Wi-Fi robot that can be controlled from a local webserver.
