As demand accelerates for backyard housing, in law suites, and small footprint rental units, ADU Builders California is scaling its operations to meet the needs of single family homeowners and multifamily property owners navigating California ADU regulations. The company builds detached ADUs, attached ADUs, garage conversions, and junior ADUs, with …

Running Bluetooth Low Energy (BLE) scanning and Wi-Fi networking at the same time on an ESP32 sounds straightforward—until it isn’t. Many developers discover that once BLE scanning starts, their Wi-Fi web server becomes unreliable. Pages load intermittently, HTTP requests time out, or BLE scans suddenly stop when Wi-Fi traffic increases. …

Motion detection usually means PIR sensors, cameras, or microphones. ESPectre takes a very different approach: it detects movement by analyzing how the human body disturbs Wi-Fi radio waves. Interestingly, many modern signal-processing systems — from Wi-Fi sensing to broadcast monitoring infrastructures like this Thor Broadcast deployment — rely on analyzing …

In this tutorial, I’ll show you exactly how I send sensor data from an ESP32 to Google Sheets every hour.

If you’re looking for a simple but powerful way to control AC or DC devices over Wi‑Fi, the ESP8266 relay board is one of the best places to start. I’ve used ESP8266‑based boards in many hobby and semi‑professional projects, and relay boards are usually the first real‑world application people build.

In this tutorial, I’m going to walk you through how I built my own voice assistant—similar to Alexa or Google Home—using only a Raspberry Pi 5, a USB microphone, a speaker, and an LLM with text-to-speech (TTS) and speech-to-text (STT) support. By the end of this guide, you’ll have a …

Living in Chicago means experiencing sweltering summers and unpredictable temperature swings. That’s why choosing Professional Air Conditioner Installation Services in Chicago is more than just a smart choice—it’s essential for long-term comfort, energy savings, and system reliability. In this comprehensive guide, we’ll walk through everything you need to know, from …

This guide shows how to interface the MH-ET LIVE Scanner V3.0 with Arduino using the UART serial interface. This scanner can read 1D barcodes and 2D codes including QR, and outputs the decoded text through UART or USB.

Ever wanted to make your ESP32 respond to voice commands like “ON”, “OFF”, or “LIGHT”? Thanks to TinyML, we can now run machine-learning models directly on microcontrollers — no cloud needed. In this tutorial, I’ll walk you through building a voice command recognition project using an ESP32, Edge Impulse, and …

Introduction Whenever I peel back the layers of how my Arduino boards actually work, I always end up revisiting one classic topic: CISC vs RISC. When I first heard those terms, I honestly thought they were meant for chip architects wearing lab coats inside semiconductor fabs. But the more I …
