Blynk — Joystick
Blynk Joystick widget, you must first generate an Auth Token
- Create a new project in the Blynk app. Choose board type (ESP32/ESP8266/Arduino) and connection type (Wi-Fi). You’ll receive an Auth Token via email.
- Add a Joystick widget to the project screen.
Raw values (0–1023) are rarely used directly. Common transformations: blynk joystick
Joystick feels laggy:
Increase your Blynk.run() frequency or reduce complex delay() commands in your loop() . Motors running backwards: Swap the motor wire connections. Blynk Joystick widget, you must first generate an Auth Token

A Pan/Tilt Servo Head
For this guide, let’s assume you are building the "Hello World" of joystick projects: . This creates a "spirit camera" that looks where you tell it to. Create a new project in the Blynk app
: Converting Cartesian coordinates (x, y) into Polar coordinates (radius, angle) is an "intuitive" way to control speed and direction for RC cars. Pan-Tilt Cameras
