The joystick is a small device that allows users to input directional information, such as up, down, left, and right, into the Micro:bit. This allows users to control the Micro:bit’s output, such as moving a cursor on a screen, or controlling the movement of a robot. The joystick can be connected to the Micro:bit board via the edge connector pins, and can be programmed to interact with the Micro:bit’s sensors and other components.
In this tutorial we will see how to display an arrow on micro:bit whose orientation depends on the direction of the joystick controller:
Micro:bit is a small, low-cost microcontroller board that was developed by the Micro:bit Educational Foundation for use in computer education. It is designed to be easy to use and accessible to a wide range of users, including children and beginners. The Micro:bit board measures about 4cm by 5cm and features a 25-pin edge connector, a 5×5 LED matrix, two programmable buttons, an accelerometer, a compass, a Bluetooth Low Energy (BLE) module, and a USB connector.
The Micro:bit is widely used in education, providing a hands-on learning experience for students of all ages to learn computer programming, logic, and problem-solving. It’s also used by hobbyist and makers to create fun and interactive projects.
Microbit GPIO board
A Micro:bit GPIO (General Purpose Input/Output) Expansion Board is an accessory that can be used to extend the capabilities of a Micro:bit by providing additional input/output (I/O) pins. These pins can be used to connect sensors and actuators, such as LEDs, buttons, motors, and other electronic components.
The expansion board typically connects to the Micro:bit using a standard edge connector and provides a set of male headers that can be used to connect external components.
A joystick is a type of input device that typically consists of a stick or handle that can be moved in different directions. The movement of the joystick is often converted into electrical signals that can be interpreted by a computer or microcontroller, such as a Micro:bit.
There are several types of joysticks available, each with their own set of features and capabilities. Some common types include:
Joysticks are commonly used in video game controllers, remote control devices, and other applications where precise control is needed. They can be used in a combination of other sensors to control a robot or other devices.
Connecting wires are used to connect various components in an electronic circuit. They allow for the transfer of electricity, data, or signals between different devices and components.
When connecting wires to an Arduino or other microcontroller, it is important to pay attention to the correct pinout. The pinout refers to the arrangement of pins on the microcontroller and the corresponding function of each pin. The Arduino pinout can be found in the documentation provided by the manufacturer, or in various resources available online.
A test plate, also known as a test jig, is a device used to test electronic circuits and components. It is a board or plate that has been designed to hold and connect various components and devices in a specific configuration, allowing for the easy testing and measurement of their performance.
A test plate can be used to test various types of electronic circuits and components, such as microcontrollers, sensors, and actuators. It typically includes connectors and sockets for connecting wires, power supply and measurement devices such as multimeters, oscilloscopes, and power supplies.
To perform the assembly we connect:
There are several mounting methods.
