Intro M8: Build 4-DOF robot arm with Pico board - Interface joystick

Описание: 🚀 Welcome to Botronix Labs! 🚀
🎮 Module 8: Joystick Control for Manual Operation | Raspberry Pi Pico Robotic Arm Course
Welcome to Module 8 of the Botronix Labs Raspberry Pi Pico Robotic Arm Series! In this hands-on session, we introduce the HW-504 analog joystick module and demonstrate how to control your robotic arm manually — a key stepping stone toward teleoperation and real-time robot control.

🔍 What You’ll Learn in This Module:

How the joystick works: potentiometers, analog voltage, and built-in push button

Understanding ADC (Analog to Digital Conversion) on the Raspberry Pi Pico

Reading and interpreting analog values using MicroPython

Mapping analog values to servo angles

Implementing real-time servo control using live joystick input

Applying dead zones to eliminate unwanted jitter

Using the joystick to smoothly rotate the base servo

(Mini Challenge) 🧠: Control the base rotation with smooth movement logic!

🛠️ Hardware Used:

Raspberry Pi Pico

HW-504 Joystick Module

Servo Motors

Breadboard and jumper wires

📦 Code and Resources:
All source code and wiring diagrams are available on our official website: 🔗 www.botronixlabs.com

📚 This module builds on:

Module 6: Controlling individual servos

Module 7: 4-DOF robotic arm assembly and smooth sweeping
