Projets IoT,
une carte à la fois.
Des projets MicroPython concrets pour ESP32, ESP8266, Raspberry Pi Pico et XIAO — capteurs, Wi-Fi, Bluetooth, tableaux de bord cloud. Chacun avec code, schémas de câblage et simulation Wokwi. Présentés dans la newsletter d'Adafruit et sur Hackster.io.
ESP32
Auto Night Light
An ESP32 reads ambient light through an LDR and switches an LED on automatically after dark. A gentle first project covering analog input and threshol…

ESP8266
TM1637 Button Counter
Count button presses on a bright TM1637 4-digit display with the ESP8266. Two-wire display driving without the bulk of an LCD.
Lire le cas →
Pi Pico
Relay Control Web Server
Flip a relay from any browser over Wi-Fi using the Pico 2W's smooth web interface. The foundation of every web-controlled appliance project.
Lire le cas →
Pi Pico
Blynk Relay Control
Control a relay from the Blynk IoT app on your phone via the Pico 2W. Cloud dashboards with zero HTML required.
Lire le cas →
ESP8266
NTP Digital Clock
The ESP8266 syncs time over the internet and shows it on a TM1637 display. No RTC module needed — Wi-Fi is the clock.
Lire le cas →
ESP8266
IR Object Detector
An IR sensor spots nearby objects and triggers an LED and buzzer on the ESP8266. Proximity sensing for automation and robotics.
