In this project, we are going to build an animatronic eye with Arduino. I got the idea to create an animatronic eye while looking for new project ideas online, and this project immediately caught my attention. First of all, it looks cool and has a simple mechanism and I learned a lot about mechatronics while working on this project. A big shout out to Will Cogley for…
While Internet of things (IoT), Industry 4.0, Machine to Machine communication etc are getting increasingly popular the need for wireless communication has become incumbent, with more machines/devices to speak with one another on the cloud. Designers use many wireless communication systems like Bluetooth Low Energy (BLE 4.0), Zigbee, ESP43 Wi-Fi Modules, 433MHz RF…
Sound direction detection is a fascinating concept in robotics and automation. It allows a device to "hear" and determine the direction of a sound. This concept has numerous applications, including robot navigation, smart security systems, gaming, and entertainment. Earlier, we showed you how to measure sound in dB using Arduino. In this tutorial, let's learn how to find the direction of sound…
At the core of the Smart Home Energy Management System is the Arduino UNO R4, which serves as the brain and central hub of this sophisticated energy management solution. The Arduino UNO R4 manages cloud connectivity through Arduino Cloud, allowing it to continuously track and report critical metrics such as battery percentage and historical data. This real-time data…
Due to the increasing population, there is a growing number of vehicles, which has led to a higher demand for parking lots in busy cities. Managing the data of vehicles entering and exiting parking lots can be quite a hassle. So today, I’ve come up with an interesting and inexpensive solution to this problem.
We are going to create a smart parking system with…
In this project, I am going to Interface an Alcohol Sensor with Arduino. Here I have designed an Arduino Shield PCB using EASYEDA online PCB simulator and designer. Arduino Alcohol Detector will detect the alcohol level in breath and by using some calculations in code we can calculate the alcohol level in breath or blood and can trigger some alarm.

Nowadays, Security system is one of the most researched fields and with increasing security threats, companies are launching new smart security products to combat these threats. IoT is an added advantage in this field which can automatically trigger an event, like calling the police, fire brigade or your neighbor, in case of any emergency. We previously built many security…
The Internet of Things (IoT) has revolutionised how we control devices, enabling seamless remote monitoring and operation over a network. This tutorial presents an innovative solution for remote stepper motor control, allowing you to precisely adjust its position, monitor its performance, and receive real-time feedback directly from a simple web browser. For those…
Electrical appliances are all around us, starting from the indispensable charger of your smartphone to heavier appliances like room heaters, air conditioners, washing machines, and whatnot. Given the status quo of a looming global energy crisis, it is vital to have an understanding of the power consumed by these devices. While our monthly electricity bill gives us a…
Thermal printer technology has revolutionised receipt printing in retail, healthcare, and IoT projects. This comprehensive ESP32 thermal printer tutorial covers how to interface popular thermal printers, such as the PNP-500, with ESP32 and Arduino microcontrollers. Whether you're building an ESP32 receipt printer, barcode printer, or QR code printing system,…
An SR latch is a basic memory element in digital electronics that stores binary data using Set and Reset inputs. This tutorial covers the SR latch truth table, the circuit diagram, and the working principle of basic, gated, and clocked SR latch variants.
Initially, after the introduction of transistors, engineers constructed simple latch circuits using transistors. After several…
In this article we are going to make a Invisible Broken Wire Detector which is used to check broken or disconnected wires inside the walls. It detects the broken wire by detecting the presence of AC voltage in the wire. When there will be AC voltage present near it, then it will start beeping and LED will go high while when there will be no AC voltage or if there will…
