How to Send Data from ESP32 to Firebase Realtime Database In this tutorial, we’re going to learn how to send data from an ESP32 to Firebase Realtime Database. We are using ESP32 Firebase Google as our cloud platform. A lot of cloud-based IoT projects on YouTube / GitHub / similar platforms using ESP32, ESP8266, UNO R4, or similar microcontrollers use Firebase as the cloud platform. And this guide covers the complete ESP32… |

ESP32-P4 Powers a DIY IP KVM for Remote PC Control Remote access devices like IP KVMs are usually built around powerful single-board computers such as the Raspberry Pi. But what if the same job could be handled by a microcontroller instead? That's what creator Jonathan Rowny set out to explore by building a functional IP KVM using Espressif's ESP32-P4. The project aimed to remotely stream a computer's display… |

How to Build an UWB Indoor Positioning System using ESP32 and Qorvo DWM3000 Building an indoor positioning system using ESP32 requires technology beyond GPS. While GPS trackers excel outdoors, indoor positioning system needs Ultra-Wideband (UWB) technology to achieve centimetre-level accuracy inside buildings. This guide shows you how to build a complete UWB indoor positioning system using the Qorvo DWM3000 UWB module with ESP32,… |

Inside the ESP32-2424S012C Development Board: Exploring the Hardware Teardown This is the teardown tutorial of ESP32-2424S012C, an ESP32 C3-based development board with an integrated display. This device comes in very handy, as it has our favourite ESP32-C3 onboard, a 1.28” IPS Capacitive Touch Screen display with a 240×240 px resolution. The coolest thing about this is that it can be custom-programmed to our specifications using a wide range… |

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… |

Five-Servo Bipedal Robot Walks and Self-Balances on a Budget A maker has built a two-legged walking robot using just five RC servos, an ESP32 microcontroller, and 3D-printed parts, making it the third entry in a series of accessible open-source robot designs. The project follows earlier builds in the same series: a mini robot dog and a hexapod. The creator set two design requirements: the robot must actively balance as it walks, and it must lift its… |
