Blynk Joystick ((better)) -

// 4. Map the values // Joystick sends 0-255. Servos usually like 0-180 degrees. int panPos = map(xVal, 0, 255, 0, 180); int tiltPos = map(yVal, 0, 255, 0, 180);

Toggle "Auto-Return" ON so the joystick snaps back to the center when released. 2. Programming the Blynk Joystick (ESP32/Arduino)

BLYNK_WRITE(V1) int x = param[0].asInt(); // Get X-axis value int y = param[1].asInt(); // Get Y-axis value // Example: Basic logic for a 2-wheel robot if (y > 200) moveForward(); else if (y < 50) moveBackward(); else stopMotors(); Use code with caution.

BLYNK_WRITE(V1) int x = param.asInt(); int y = param.asInt(); // Use the x and y values to control your robot or IoT device analogWrite(joystickX, x); analogWrite(joystickY, y);

Note: Virtual pins work similarly but must be declared in Blynk 2.0 web dashboard.
