This circuit demonstration showcases a random LED flasher controlling twenty lights. LED flashers and sequencers are commonly employed in decorative lighting applications to produce aesthetically pleasing color patterns. Rather than steadfast illumination, these systems cycle LEDs on and off in either a predetermined sequence or at irregular intervals. The latter approach generates a more dynamic, […]
It is common for parents to feel concern for their children when they are apart. Questions arise around whether the kids made it safely to school, if they are alone at home, or playing with friends at the park. Ensuring a child’s well-being when away creates worry that is familiar to caregivers worldwide. The natural […]
This project demonstrates building a real-time clock (RTC) with temperature display using an Arduino, DS3231 RTC chip, and SSD1306 OLED display (128×64 pixels). The DS3231 RTC chip provides more accuracy than the DS1307 and incorporates an onboard temperature sensor. It maintains timekeeping even without the main power, making it well-suited for this application. It communicates […]
This system allows remote control of up to four industrial devices using a joystick and Arduino Nano microcontroller board. Figure 1 presents a block diagram of the joystick-controlled industrial automation setup. Key components include: An Arduino Nano which processes signals from the joystick and outputs control commands. A joystick module that generates analog position readings […]
This Arduino Uno and IR sensor-based system automatically controls the lighting in a bathroom connected to AC mains power. The IR sensors detect when a person enters or exits the room. Upon detection of entry, the light bulb or tube light is immediately switched on. When the sensors no longer detect a presence, the lighting […]

The BlueNRG-LPS supports Bluetooth Low Energy 5.3, enabling point-to-point connections and Bluetooth Mesh networking to reliably establish […]
Introduction Arduino serves as a development platform for creating embedded applications, incorporating a variety of sensors and actuators. It relies on open-source hardware, offering a range of Arduino models for your development needs. This book is tailored for developers, particularly those proficient in .NET, who aim to craft Arduino programs for both general and specialized […]
This tutorial provides a straightforward guide for crafting a small security device with an Arduino. Step 1: Assemble Materials Step 2: Setup Attach a red wire from the 5V pin on the Arduino to the positive segment of the breadboard. Establish a connection with a black wire from the GND pin on the Arduino to […]
Store MIDI files on an SD Card and utilize an SD shield connected to your Arduino to play these songs on a MIDI device. This project illustrates the creation of an Arduino-based MIDI player. The Arduino is linked to a DS1307 Data Logger Shield equipped with an SD Card reader. It generates a MIDI stream […]
The intention behind this guide is to furnish valuable insights into the typical sensors employed in the RAD SLDP. It’s worth noting that sensors produced by various manufacturers might have slight variations compared to the ones outlined in this guide, but comprehensive documentation for all these sensors can be easily accessed online. If you require […]
