Which OS is best? There are so many OS (Operating System) options out there for the Raspberry Pi, it makes choosing the right one for you a bit of a mine field!  First of all, what exactly is an OS and why do you need one?  Essentially, an OS is the software that supports a computer’s basic functions. For example, a computer needs an OS to execute scheduling tasks, control peripherals and execute...

Blinking an LED in python has become really easy due to the new GPIO Zero library. There's a few different ways. Lets begin by just turning the amber LED on. Open up your favourite python editor and type in the following to turn it on. from gpiozero import LED amber = LED(23) amber.on() And then try "amber.off()" to turn it off. We can make the LED now blink by adding the following code at...

Following on from the previous tutorial of blinking an LED using GPIO Zero we're going to expand into creating a traffic light program. However instead of using the separate modules for the LED And buzzer there is a neater way that we can do it using the TrafficHAT Add-on function. Begin by adding the following code to setup the TrafficHAT replacing Ryan Walmsley with your name. #TrafficHAT Program #TrafficLight By Ryan Walmsley from gpiozero...

The following code will blink each LED one at a time. GPIO Zero Setup Instructions can be found here You can run this code by putting it into a python file and then running it with python. #SnowPi Test Code import random import time from gpiozero import LED #Setup all the LEDs led7 = LED(7) led8 = LED(8) led9 = LED(9) led17 = LED(17) led18 = LED(18) led22 = LED(22) led23 =...

To begin please make sure you have the latest version of GPIO Zero Installed. You can follow our guide on installation @ GPIO Zero Install. Getting SnowPi working is actually very simple and is done in minutes after setting up GPIO Zero using the guide above. First we need to check the numbers of the GPIO Pins we need to use. We'll begin by blinking the...

This tutorial will go over writing your first program and using the RTk.GPIO and assumes you've already followed the guide to install python and the library installed. If not follow the guide here. I'm still writing this. The demo code below should work fine if you change the number 22 to the pin which an LED is connected to (I used Pin 22 as its Green on the TrafficHAT. Changing it to 4 should...

At the bottom of the motor controller there are 3 Terminal Blocks. These are labeled: Motor 1 & Motor 2 - These are the motor blocks. In each block you can wire one motor into each block. These are Bi-directional so it doesn't matter which side of the motor goes into the pins on the block. The direction is then controlled via code. VCC2 - This is the power in to power the motor controller IC and is the...
