What is an ESP32 Web Server? 

In the Internet, all the websites are hosted on a computer and this computer is called a server. Since this particular server is used to serve web pages and web requests, we call it a web server. Instead of using a computer, we can also use an ESP32 to respond to web requests, thanks to the ESP32’s built-…

A stepper motor is a type of brushless DC motor that divides a full rotation into several steps, thus allowing for precise control of the motor's position. The A4988 stepper motor driver is a versatile stepper driver for controlling stepper motors for various applications. When combined with an Arduino UNO microcontroller, the A4988 stepper driver provides highly…

The DHT22 temperature and humidity sensor is a versatile and cost-effective sensor used to measure ambient temperature and humidity for a wide range of applications. It is based on a digital signal output and can provide high-accuracy measurements with a resolution of 0.1 degrees Celsius for temperature and 0.1% for humidity. The sensor uses a capacitive humidity…

A 4x4 membrane keypad is a compact and a cost-effective input device that is commonly used in a variety of electronics projects. It consists of 16 buttons arranged in a 4x4 grid and is covered with a flexible membrane that protects the buttons and ensures their durability. In this blog, we'll go over how to interface a 4x4 membrane keypad…

A single-channel relay is an electronic switch that can be controlled by a low-power electrical signal, such as the output from an Arduino microcontroller. By using an Arduino Uno and a single-channel relay module, you can control high-voltage or high-power devices, such as lights, motors, and appliances, from your computer or mobile device…

In this project, we are going to build an audio bug using Arduino and NRF24L01. This audio spy bug is highly customizable and can be easily integrated with other devices and systems. The NRF24L01 module allows transmission over specific channel, ensuring that our transmissions remain private up to a level. This device is perfect for…

In the previous parts(Part 1, Part 2, Part 3) of this project, we investigated different aspects of our smart watch projects and learned to integrate and test each individual part. In this we are going to use what we have learned to create our own smartwatch from scratch, using a combination of hardware and software components. Throughout…
