How to Build a Parking Space Detection System Using ESP32-CAM with CircuitDigest Cloud 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… |

How to Build a Face Detection System Using a Raspberry Pi and CircuitDigest Cloud 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… |

Build an ESP32 GSM Calling Device with Auto Answer Using GeoLinker 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… |

How to Build a Smart Indian Currency Recognition Using ESP32-CAM 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… |

How to Do Helmet Detection with ESP32-CAM Using CircuitDigest Cloud 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-… |

Smart WLED Clock with RTC, PIR, Audio feedback and Environmental Monitoring 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… |

ESP32 Interactive Voice Response (IVR) System with GeoLinker Integration Nowadays, automation has become a common part of our daily lives. From simple tasks like operating a coffee machine to creating code for complex applications, many processes are now automated. However, most systems used for controlling devices depend on internet connections, mobile applications, or cloud platforms. In many places, internet availability may be poor or… |

Automatic Waste Segregation System Using Arduino UNO Q Proper waste sorting is very important for keeping our neighbourhoods clean and saving resources for the future. When we mix food scraps, plastic, paper, and batteries in the same bin, recycling becomes hard, landfills fill up quickly, and harmful chemicals leak into the soil and water. Over time, this creates bigger problems like higher cleanup costs and more damage… |
