This DIY tutorial is all about making our home lighting smart and fun without any complicated steps. We can connect a standard 12V LED strip to a tiny wi-fi chip and build our own ESP32 WLED controller custom smart lighting system, which can be completely controlled from a smartphone or computer.

This DIY ESP32 based WLED controller…

Everybody likes weekends. On weekends, you often drive with your family to crowded places like malls, theme parks, or circuses for outings and relaxation. But then comes one of the most frustrating parts of the trip: searching for parking. Sometimes, finding a parking space feels even harder than waking up early in the morning.Even if there is a security guard or…

Running, running, every day, we keep running to work, school, and college. In this busy routine, many of us do not even have enough time to eat breakfast properly. Then where do we find the time to clean our homes? Even when we clean, because of laziness or lack of time, we often throw all waste into the same bin without separating biodegradable and non-biodegradable waste. This creates a…

What if a device could see the world the same way humans do, seeing objects, recognizing them, and understanding what they are in real time? Just like our eyes capture visuals and our brain instantly processes them, from bottles and phones to people and everyday items. It will be pretty cool, right? That is exactly what this Raspberry Pi object detection project demonstrates. You can build a…

As adults, it is our duty to follow traffic rules, and the most important rule is to wear a helmet while riding a two-wheeler and not to cross the speed limit. It's not a rule, but it's also for safety. Now, let’s think from the traffic police officer’s side. Their duty is to monitor traffic and check whether everyone is following the rules, but it is quite difficult for a traffic officer to…

Imagine driving into a crowded parking area and not knowing whether a space is available or not. This project solves exactly that problem by building a smart, automatic parking space detection system using the ESP32-CAM and the CircuitDigest Cloud API. With just a button press, the device captures a real-time image of the parking area and sends it over the internet…

When we see movies, we often see scenes where a villain uses a gun with a face detection system that automatically targets a person accurately. It may look like a very complex technology that is difficult to build on our own, right? Not anymore.  Building a face detection system using a Raspberry Pi might sound like something out of a Hollywood thriller, but it…

In this project, we build a complete ESP32 GSM voice calling device using the GeoLinker GL868 board. The main idea of this project is very simple. When we press a push button connected to the ESP32 board, it will automatically call a fixed phone number. Also, if someone calls the SIM card inside the module, the call will be automatically attended, and we can talk…

Many visually impaired people identify currency notes by touching them. But as people grow older, their touch sensitivity may gradually decrease, making it difficult to recognise the correct denomination accurately. Imagine an elderly shopkeeper in a small roadside store who has weak eyesight and struggles to identify the money given by customers. In such situations…

If you are working on IoT projects, you already know the importance of an M2M IoT SIM card for remote monitoring and tracking. For those who are new and wondering why you need a special M2M SIM card when you can just use your normal SIM card, here are two strong reasons to consider one.

Cost: If you are running a…

Think of a busy road where hundreds of riders pass every minute, some wearing helmets, many not, and imagine trying to monitor all of them manually. It’s almost impossible to keep track in real time. Now imagine a small device quietly watching the scene, capturing an image with a single trigger, and instantly telling you whether safety rules are being followed. That is exactly what this ESP32-…

The integration of addressable LEDs with the WLED firmware has revolutionized DIY lighting projects, allowing for complex visual effects with minimal to no coding.  However, most standard WLED-based clocks face significant limitations, such as time-drift during internet outages and continuous power consumption regardless of room occupancy and no alarms. To address these issues, this…
