An arduino robot kit landed on my kitchen table three years ago as a birthday gift, and I had no idea what half the parts were for. If you’re staring at a similar box right now, or trying to pick one before you buy, I want to walk you through what I learned the hard…

The first time I saw the Core ESP32-C3 Board for Arduino, I almost ignored it. It looked like another tiny development board promising faster performance, built-in Wi-Fi, and Bluetooth. After years of experimenting with Arduino boards, I’d learned that flashy specifications don’t always translate into a better building experience. My old Arduino Uno had never…

Have you ever wanted to control an Arduino project wirelessly using your smartphone? Whether it’s turning LEDs on and off, controlling a robot car, or sending sensor data to your phone, the HC-05 Bluetooth module makes it surprisingly easy. The good news is that you don’t need advanced programming skills to get started. With just…

If you’re just entering the world of electronics, programming, or DIY tech projects, you’ve probably heard about Arduino and Raspberry Pi Foundation. And honestly, most beginners get confused here. Should you start with Arduino?Or is Raspberry Pi the smarter choice? Here’s the thing… both are amazing, but they are built for different purposes. Choosing the…

The Internet of Things is exploding – globally, over 21 billion IoT devices are expected by 2025. In the US alone, the IoT market is valued at $413.22 billion in 2024 and growing fast. With so many connected devices, reliable networking is critical. For many Arduino-based projects, using wired Ethernet gives better speed, stability, and security than Wi-Fi. The arduino_event_eth feature (often tied…

Table of Contents Periodt showed up in my replies before I ever bothered to look it up. Someone tagged a comment with nothing but that one word, no punctuation, no follow-up. I remember squinting at my screen, positive they’d fat-fingered an extra letter. They hadn’t. Turns out that little T is pulling its own weight,…

Why I Almost Sent My First Core ESP32-C3 Board Back My first core ESP32-C3 board for Arduino sat in a static bag on my desk for almost two weeks before I worked up the nerve to plug it in. It came from a marketplace listing that simply read “CORE ESP32-C3 development board.” No manual. No…

I have been building small electronics projects for over six years, mostly custom keyboards and desk gadgets. Everything in this article comes from boards I have soldered, bricked, and eventually gotten working on my own bench. What Is the Arduino Pro Micro The Arduino Pro Micro is a small board built around the ATmega32U4 chip,…

The Midnight Debugging Session While debugging a remote telemetry project last month, I encountered the arduino_event_wifi_sta_got_ip esp32 event issue that has tripped up many IoT developers. My solar-powered weather station was supposed to wake up, connect to the local access point, transmit sensor payloads, and immediately return to deep sleep. Instead, the controller hung in…
