How to Make a Waste Detection Using ESP32-CAM with CircuitDigest Cloud In our day-to-day life, huge amounts of waste are generated in homes, streets, offices, and public places. But the real problem is not just collecting the waste; it is separating it correctly. When biodegradable waste like food waste and leaves gets mixed with non-biodegradable waste like plastic bottles and metal cans, recycling becomes difficult and environmental pollution increases. Manual… |

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… |

This DIY Voice Recorder Uses AI to Turn Spoken Ideas into Summarized Notes A maker recently built a compact portable voice recorder designed specifically for capturing ideas before they are forgotten. Instead of relying on a smartphone app, the project focuses on a dedicated hardware workflow built around an ESP32, combining local audio recording with AI-based transcription and summarization. The device records audio directly to an SD card, provides onboard playback… |

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-… |

ESP32 Speech-to-Text using Wit.ai In this project, we’ll be learning how to build an ESP32 Speech to Text system using an ESP32 development board. We’ll use an I2S MIC to record speech and an OLED display to display the converted text. In addition to the display, the text will also appear in the serial monitor. Since ESP32 cannot run a Speech recognition model locally due to its hardware… |

How to Do Object Detection With ESP32-Cam Using CircuitDigest Cloud This tutorial shows you how to build a real-time object detection system using the ESP32-CAM module and the CircuitDigest Cloud Object Detection API. The system captures an image on button press, sends it to the cloud via wireless or internet connection, retrieves the identified objects with name(s), how many there were and how confident (how much certainty the algorithm has) of the object… |
