| 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; |

: The joystick returns to the center position when you lift your thumb.

Example Project: Controlling a Robot with ESP32 and Blynk Joystick blynk joystick

To use the joystick, you must have an active Blynk IoT account and a created Template. : Log in to blynk.cloud.

// Set the direction and speed for Motor B if (motorSpeedB >= 0) digitalWrite(in3, HIGH); digitalWrite(in4, LOW); analogWrite(enB, motorSpeedB); else digitalWrite(in3, LOW); digitalWrite(in4, HIGH); analogWrite(enB, -motorSpeedB); // Set the direction and speed for Motor

The Blynk Joystick has a wide range of applications across various industries, including:

: In the Blynk App Settings , you can map the boundaries of your joystick (e.g., -255 to 255 for pulse-width modulation motor speeds or 0 to 180 for servos). The Joystick widget is unique because it sends

The Blynk Joystick widget provides an excellent low-code solution for 2-axis remote control. However, due to the Legacy platform shutdown, new projects should use:

Create a new template for your device (e.g., ESP32 or NodeMCU).

The Joystick widget is unique because it sends on one virtual pin . In your Arduino sketch, you will use the BLYNK_WRITE() function to read these values. param[0] : Represents the -axis value. param[1] : Represents the -axis value. Coding Example: Controlling a Robot with Blynk

To ensure smooth operations and avoid burning out hardware, consider these best practices:
