Blynk is an IoT platform that enables you to create a mobile app to control your Arduino, Raspberry Pi, or other IoT devices. It's a popular platform among makers, hobbyists, and professionals alike.

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.

Ensure external 5V supply for servos (not from ESP32's 3.3V pin).

Security cameras or tracking systems mounted on dual servos can be manually overridden using the joystick. The X-axis maps directly to the pan servo angle ( 0∘0 raised to the composed with power 180∘180 raised to the composed with power ), while the Y-axis controls the tilt servo.

Constrain your final mixed values to your system's maximum limits using the constrain(speed, -255, 255) function to prevent variable overflows.

So what will you build? Grab an ESP32, download the Blynk IoT app, add a joystick to your dashboard, and start controlling the world from your smartphone today. Ensure external 5V supply for servos (not from ESP32's 3
