A sporty, realistic RC car built from ExoSynk shapes and the new Wheel part — open the World tab and drive it with the keyboard.

A functional, sporty RC car — realistic Wheel parts driven by a real skid-steer circuit through the connector drivetrain. Control it from the Action panel or drive it with the keyboard in World.

A complete working torch with 3D enclosure design. Battery, switch, resistor, LED — the classic first electronics project.

Seven Arduino digital pins drive a common-cathode 7-segment display. A shared 330Ω resistor limits current to ground. Code counts 0→9 in a loop.

Two 10kΩ resistors in series across a 9V battery. The tap in the middle sits at 4.5V. Try different R1/R2 ratios.

Arduino Uno multiplexing four common-cathode 7-segment displays into a 24-hour clock. Buttons on A0 and A1 adjust the hour and minute.

The hello-world circuit: 9V battery, 330Ω resistor, LED, ground. Fork it and try a 3V battery, or a 100Ω resistor to watch the LED burn out.

Classic analog circuit — no Arduino. An LDR forms a voltage divider that drives an NPN base. LED turns on only when ambient light drops. Four parts, one transistor, zero code.

Arduino drives a common-cathode RGB LED through three 330Ω resistors. Code cycles R, G, B via analogWrite — classic PWM color mixing.

Flagship ExoSynk demo — autonomous RC car with L298N drive, HC-SR04 obstacle avoidance, MPU6050 tilt detection, OLED + NeoPixel status, BT remote override, and a beveled 3D chassis.

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.

9V battery, 10kΩ resistor, 100μF capacitor. Time constant τ = 1 second. Open the oscilloscope on V_cap to see the exponential rise.
