// Attach servos servoPan.attach(PIN_PAN); servoTilt.attach(PIN_TILT);

Remote control used to mean bulky radio transmitters and tangled wires. Today, the Blynk IoT platform allows you to turn your smartphone into a sophisticated remote controller with just a few drags and drops. At the heart of many robotic and motion-based projects is the . blynk joystick

To process the "long piece" of data coming from the joystick, you use the BLYNK_WRITE function in your Arduino/ESP32 code. // Example for a Joystick on Virtual Pin V1 BLYNK_WRITE(V1) x = param[ ].asInt(); // Get X-axis value y = param[ ].asInt(); // Get Y-axis value // Example: Control motors based on X and Y Serial.print( ); Serial.print(x); Serial.print( ); Serial.println(y); Use code with caution.

It serves as the "key" that allows your device to communicate with the specific joystick widget you place on your app dashboard. Step 2: Configure the Joystick Widget To process the "long piece" of data coming

To implement a joystick in your project, follow these general steps: Joystick widget from the Widget Box. Datastreams
