🚗 Meet the flagship ExoSynk demo: an autonomous RC car that drives itself, dodges obstacles, survives tilt, talks to a virtual BT remote, and displays live telemetry — all in your browser.
• L298N H-bridge with real PWM
• HC-SR04 obstacle avoidance via pulseIn()
• MPU6050 tilt detection over I²C (full register map)
• SSD1306 OLED + 8-LED NeoPixel status
• Beveled-box 3D chassis with revolved tires (STL-exportable)
• Live physics map — watch the car drive
Same sketch runs on real hardware. Build virtually, ship physically. Attached lab is ready to fork. Tutorial linked below. ↓

v0.12.9 is live. Three new parts in the 2D lab:
• ESP32 DevKit — full GPIO/analog/3V3
• Raspberry Pi Pico — GP0..GP15 + VBUS + 3V3
• Hobby servo — rotating arm follows the position prop 0..180°
Plus: the DC motor actually spins in the sim now (direction follows current polarity, speed scales with amps).
Built a demo that uses all of it — ESP32 driving a servo with a status LED. Five parts, twenty lines of code. Full walkthrough: @L/exosynk/esp32-servo-sweep

Tutorial
Your first ESP32 build: a servo that sweeps
@exosynk
Five parts and twenty lines of code. How the ESP32 talks to a hobby servo, why the status LED lives on GPIO23, and how to verify every wire in the sim before you touch hardware.

Project
ESP32 servo sweep with status LED
@exosynk
A 5-part starter project using the new ESP32 DevKit + hobby servo. GPIO18 drives servo signal, GPIO23 lights a status LED while the code is running.
