The “I Can’t Focus” Problem I have a confession. I sit down to study. I open my laptop. I swear I’ll work for one hour. Twenty minutes later, I’m watching a video about how to build a robot that makes coffee. Ten minutes after that, I’m checking my phone. Five minutes later, I’m staring at…

Table Of Contents The “I Built My Own RC Car” Moment I still remember holding the joystick for the first time, pushing it forward, and watching the little robot chassis zoom across my room. Not a toy from a store. Not a kit where everything just snaps together. Something I built. Wires, motors, ESP32s, code—all of it….
The “Wait, Did I Just Say That?” Moment I still remember the first time I said: “Hey Google, turn on the desk LED.” And the light actually turned on. I sat there for a second, staring at the bulb, half expecting it to be a coincidence. It wasn’t. My ESP32 had heard me. Google Assistant had…

The Package That Confused Me A few weeks ago, a tiny package arrived at my doorstep. Inside was something so small I almost lost it in the packaging material. I held it up and thought: “This… this is a microcontroller? It’s smaller than my thumb.” For comparison, here it’s next to my Arduino Uno: This little…
The Confession (Arduino IDE vs Platformio) I have a secret. Before I started playing with robots, I already loved VS Code (But that doesn’t mean I’m blindly biased toward it 🫠).
