Whether you are building a WiFi-controlled car, a pan-tilt camera mount, or a robotic arm, the joystick provides an intuitive way to send complex 2D coordinates to your hardware. 🛠️ How the Blynk Joystick Works
| Use Case | Mapping Function | |----------|------------------| | Servo angle | angle = map(x, 0, 1023, 0, 180); | | Motor speed ±100% | speed = map(x, 0, 1023, -100, 100); | | Deadzone (center) | if (abs(x-511) < 20) x = 511; | | Analog 0-255 | pwm = x / 4; | blynk joystick
