Vision development boards are useful when an embedded project needs to combine image capture, local display, audio input, storage and wireless connectivity in a single platform. The ESP32-P4X-EYE takes this approach around the ESP32-P4, adding an ESP32-C6 wireless module, a 2MP MIPI-CSI camera, a 1.54-inch SPI LCD, a digital microphone, MicroSD storage, USB…

A tiny smart button measuring just 32 millimeters in diameter is demonstrating how modern IoT hardware can deliver powerful functionality in a miniature package. At its core is the Nordic nRF54L15 chipset, a next-generation wireless microcontroller designed for ultra-low-power embedded applications. The board supports Bluetooth Low Energy and Matter over Thread,…

Not being able to locate a friend who got separated from the group during a trek led to the development of Mesh Node, a device designed for connectivity in areas where traditional infrastructure does not exist. It uses LoRa tech to support messaging over distances of up to 4–5 kilometres in open areas. The range of communication extends even longer by forming a mesh network, where devices…

Stressful day? Deadlines, noise, overthinking, endless scrolling… sometimes the best thing you can do is pause everything and play a game. Games have always been more than just entertainment; they refresh the mind, shift our focus, and quietly reset our mood. When we play, stress doesn’t just reduce… it bursts. And let’s be honest, gaming isn’t just for kids anymore…

Ever thought of controlling your computer using buttons and a knob that actually feel different when you use them? Most input devices, like keyboards and mice, only give visual feedback on the screen and do not provide any physical sensation to indicate how an action feels. The Macropad changes this experience by adding the sense of touch to everyday computer controls. This is a six-button…

Consider a fast-moving car, if it suddenly gets hit by another car in opposite direction, the first thing that happens is that, the accelerometer sensor present in the car senses a sudden de-acceleration and triggers an external interrupt to the microcontroller present in the car. Then based on that interrupt the microcontroller produces an electric signal to deploy the…

It is always interesting to build things that could be used in our day to day life and it gets more interesting when the same can be built easily at a very low cost. In this tutorial we will learn how to build a simple yet powerful MP3 player that could play any MP3 song, the volume and track can also be adjusted with the help of push buttons. With some extra effort you can…

In this session we are going to use Raspberry Pi and the PYGAME functions to make a sound board. In simple terms, we are going to connect few buttons to the Raspberry Pi GPIO pins and when these buttons are pressed Raspberry Pi plays audio files stored in its memory. These audio files can be played one by one or they can all be played together. In other words you can press…

Raspberry Pi is an ARM architecture processor based board designed for electronic engineers and hobbyists. The PI is one of most trusted project development platforms out there now. With higher processor speed and 1 GB RAM, the PI can be used for many high profile projects like Image processing and Internet of Things.

For doing any of high…

The name Arduino is typically buzz word among most of the electronics students or hobbyists alike. Its ability to build things faster and cheaper with a massive online community support has made it an ideal choice for many people who are just getting started with electronics or programming. Because of its simplified hardware design and programming environment, it is possible…
