Touch Sensitive Color Changing Plants using Arduino and RGB LEDs Touch Sensitive Color Changing Plants using Arduino and RGB LEDs

In this article, we will learn how to build a touch-based color-changing plant using Arduino. When you touch the plant, the color of the plant vase will automatically change. This is a nice indoor decorative project and also a small hobby project for beginners to build and learn some interesting stuff. Previously we have also built a touch-based music player using Arduino,…

Jumper less Breadboard Rapid Prototyping Made Easy with the Jumper less Breadboard

The breadboard, a staple tool in the realm of electronics, allows for rapid prototyping of electronic circuits without soldering or PCB creation, despite its drawbacks like high parasitic capacitance and resistance. Kevin Santo Cappuccio has introduced a modern twist with his jumper less breadboard design, utilizing 12 analog cross point…

DIY ESP32 Oscilloscope DIY ESP32 Oscilloscope

The oscilloscope is a must-have test instrument for any electronics engineer. It is used to visualize and observe various signals, usually as a two-dimensional plot with one or more signals plotted against time. They are used in designing and debugging electronic devices to view and compare waveforms, and determine voltage levels, frequency, noise, and other…

Reverse Polarity Protection Circuit using RT1720 Over Voltage, Over Current, Transient Voltage & Reverse Polarity Protection Circuit using RT1720 Hot Swap Controller with Fault Timer

Oftentimes in an electronic circuit, it's absolutely necessary to use a special protection unit to protect the circuit from overvoltage, overcurrent, transient voltage, and reverse polarity and so on. So, to protect the circuit from these surges, Richtek Semiconductor introduced the RT1720A IC which is an oversimplified protection IC designed to meet the needs. The low-cost…

Fingerprint based Car Ignition System Fingerprint based Car Ignition System using Arduino and RFID

Nowadays most of the car comes with keyless entry and push-button ignition system, in which you only need to carry the key in your pocket and just need to put your finger on the capacitive sensor on the door handle to open the car door. Here in this project, we are adding a few more security features to this system by using RFID and Fingerprint sensor. RFID sensor will…

Portable Arduino-based Load Scale with HX711 Weight Sensor Portable Arduino Weighing Machine with Set Weight Option for Retail Packing

Digital load scales are another miracle of modern-day engineering and design. Yes, we are talking about the weighing scale we often see in most of the grocery stores and other places, but have you ever wondered how a weight scale work? To answer that question, in this project, we are going to take a look at the load cell and its working. Finally, we will be building a…

DIY ATtiny85 USB Rubber Ducky DIY USB Rubber Ducky using ATtiny85

The USB Rubber Ducky or Bad USB is a famous attack tool that looks like a USB pen drive but acts like a keyboard when plugged into any unlocked device. The USB Rubber Ducky allows attackers to program microcontrollers in USB devices to perform various tasks. It can be programmed to inject keystroke and binary files into a system, get the cached password to hack a system…

AC Phase Angle Control Circuit AC Phase Angle Control for Light Dimmers and Motor Speed Control using 555 Timer and PWM Signal

Home automation systems are increasingly gaining popularity day by day, and nowadays it's become easy to turn on & off certain appliances by using some simple control mechanism like a relay or a switch, we have previously built many Arduino based Home Automation Projects using relays. But there are many home appliances that require control of this AC power rather than…

Air Quality Analyzer using Arduino Air Quality Analyzer using Arduino and Nova PM Sensor SDS011 to Measure PM2.5 and PM10

Air pollution is a major issue in many cities and the air quality index is getting worse every day. According to the World Health Organization report, more people are killed prematurely by the effects of hazardous particles presented in the air than from car accidents. According to the Environmental Protection Agency (EPA), indoor air can be 2 to 5 times more toxic than…
