Me Joystick

Overview

Including a cross joystick, Me Joystick Module is used to control the moving direction of cart and the interactive video game. Its black ID means that it has an analog port and should be connected to the port with black ID on Makeblock Orion.

Technical specifications

Operating voltage: 5V DC
Signal node: 2-shaft analog output
Cross joystick: comprising two potentiometers and a gimbal
Module size: 51 x 24 x 32 mm (L x W x H)

Functional characteristics

White area of module is the reference area to contact metal beams
The gimbal separates displacement of joystick into horizontal (X) and vertical(Y) components
Collect analog signal of potentiometer voltage to identify the position of joystick
Anti-reverse protection – connecting the power supply inversely will not damage IC
Support mBlock GUI programming, and applicable to users of all ages
Adopt RJ25 port for easy connection
Provide pin type ports to support most Arduino Baseboards

Pin definition

The port of Me Joystick Module has four pins, and their functions are as follows:

Wiring mode

● Connecting with RJ25

Since the port of Me Joystick Module has black ID, you need to connect the port with black ID on Makeblock Orion when using RJ25 port.

Taking Makeblock Orion as example, you can connect to ports No. 6, 7, and 8 as follows:

● Connecting with Dupont wire

When the Dupont wire is used to connect the module to the Arduino UNO Baseboard, its X and Y pins should be connected to analog pin as follows:

Guide to programming

● Arduino programming

If you use Arduino to write a program, the library Makeblock-Library-master should be invoked to control the Me Joystick Module.

This program serves to read the X- and Y-axis position and output to the serial port monitor in the cycle of 10 ms through Arduino programming.
