Introduction
In this article, we will explore the Pimoroni Explorer HAT Pro and how it works with the Raspberry Pi 4B. We will cover the key concepts and provide detailed context on the topic. We will also include subtitles, paragraphs, code blocks, and an HTML unordered list for references.
What is the Pimoroni Explorer HAT Pro?
The Pimoroni Explorer HAT Pro is a stackable add-on board for the Raspberry Pi that provides a range of sensors and inputs, including a 1.2" 128x64 OLED screen, a joystick, four buttons, a five-way tactile switch, a light sensor, and a temperature sensor. It is designed to be easy to use and is compatible with Raspberry Pi models A+, B+, 2B, 3B, 3B+, and 4B.
Getting Started with the Pimoroni Explorer HAT Pro
To get started with the Pimoroni Explorer HAT Pro, you will need a Raspberry Pi 4B and the latest version of Raspberry Pi OS (formerly Raspbian). You will also need a male GPIO header to connect the HAT to the Raspberry Pi.
Once you have all the necessary components, you can follow these steps to get started:
- Connect the Pimoroni Explorer HAT Pro to the Raspberry Pi using the male GPIO header.
- Power on the Raspberry Pi.
- Open a terminal window and run the following command to install the necessary software:
sudo apt-get update sudo apt-get install python3-pimoroni - Connect to the OLED screen by running the following command:
sudo apt-get install python3-pimoroni-piscreen - You can now run the example scripts provided by Pimoroni to test out the various sensors and inputs on the HAT.
Key Concepts
GPIO Pins
The Raspberry Pi has a set of General Purpose Input/Output (GPIO) pins that can be used to connect sensors, lights, and other electronic components. The Pimoroni Explorer HAT Pro connects to these pins to provide access to its sensors and inputs.
I2C Communication
The Pimoroni Explorer HAT Pro uses I2C communication to communicate with the Raspberry Pi. I2C (Inter-Integrated Circuit) is a communication protocol that allows multiple devices to be connected to a single bus. It is commonly used in embedded systems and is supported by the Raspberry Pi.
Sensors and Inputs
The Pimoroni Explorer HAT Pro includes a range of sensors and inputs, including:
- 1.2" 128x64 OLED screen
- Joystick
- Four buttons
- Five-way tactile switch
- Light sensor
- Temperature sensor
Code Example
Here is an example of how to use the joystick on the Pimoroni Explorer HAT Pro:
import time
import pimoroni
# Initialize the joystick
joystick = pimoroni.Button(0, 0, pimoroni.JOY_CENTRE)
while True:
# Read the joystick position
x, y = joystick.read()
# Print the joystick position
print("X: {}, Y: {}".format(x, y))
# Wait for a short period of time
time.sleep(0.1)
