Tutorials for makers who actually ship.
Every tutorial is built on our own boards, reviewed by an engineer, and paired with the exact kit on our shop. No dead ends.
ESP-NOW: Wireless mesh without Wi-Fi.
Build a low-latency, peer-to-peer protocol that runs on bare ESP32 — no router, no broker, ~250 byte packets. We'll send sensor data between two boards and visualize the round-trip live.
All tutorials
First Blink: Hello, ESP32
Set up Arduino IDE, flash your first sketch, and master the GPIO basics.
ESP32 Bluetooth Quick Start
Pair your phone, send your first byte, watch the LED toggle. 5 cards, ~6 minutes, no fluff.
Reading Analog Sensors with the ADC
How the ESP32's 12-bit ADC actually behaves — calibration, attenuation, noise.
Wi-Fi Connection Manager
Robust auto-connect with fallback AP mode and provisioning over a captive portal.
ESP-NOW: Wireless without Wi-Fi
Peer-to-peer, low-latency, no router. The protocol you wish you knew sooner.
BLE Beacons & Scanners
Advertising, scanning, GATT services — build a presence-aware device.
MQTT with HiveMQ in Production
TLS, last-will, QoS — patterns that actually survive a flaky network.
I²C Multi-Sensor Bus
Wire four sensors on one bus, deal with address clashes, and pull data fast.
OLED Graphics & Custom Fonts
Beyond Hello World — anti-aliased glyphs, animations, and frame budgets.
Deep Sleep & Wake Sources
Drop to 10 µA, wake on touch, timer, GPIO, or ULP — pick the right one.
TensorFlow Lite: Keyword Spotting
Train a tiny model, deploy on-device, recognize 'on/off' in ~80 KB of RAM.
ESP32-CAM Object Detection
Stream JPEG frames, run a small detector, draw boxes over a web UI.
Designing Your First PCB
From breadboard to fab-ready Gerbers using KiCad — what to actually check.
