Description

The game emulates the starting lights of a F1 race using the LEDs which light up until they are all lit. When the lights go out the race has started and you need to break the beam to record a time. I have even thrown in a poor impression of the starting engine sound :) You should now see a ‘Raspberry Pi Pico’ panel on the left-side of Thonny, and information in the bottom-right ' Shell' panel. Tip: If you don't see your Pico on the left, try selecting 'View' from the top navigation bar, and selecting 'Files'. These sensors are commonly used in home alarm systems - if your home has an alarm, have a look in the corners of the ceilings and you may see something similar. We've been using time.sleep a lot over the last ten days, however we're going to use another part of that module today.

All we're doing here is taking our target score, dividing it by 100 to give us 1%, then multiplying that by whatever percentage of score completion we want each LED to light at - and then compare that to the players score. There are a few new elements in the example code that we need to introduce, so let's go over them first... Time and Epoch For new coders - The included Pico H and project parts combined with the easy-to-follow instructions, clear example code and helpful wiring diagrams make this perfect for anyone wanting to get started with the Raspberry Pi Pico, programming and electronics. Now just make sure that ‘MicroPython (Raspberry Pi Pico)' is selected in the first drop-down box, select the available device in the ‘Port’ drop-down, then select ‘OK’. Letter case is very important with MicroPython and other code languages. Our print is always ' print' and never ' Print'.With the first day’s box giving you a new pre-soldered Raspberry Pi Pico H, Micro-USB cable and breadboard, all you need is a compatible computer (with a full-size USB port) to plug it into - a Windows PC, Mac or Linux machine (Chromebooks are NOT compatible). It uses similar code to the example above, but we make it a little busier by adding in the LEDs with a new variable to set a target ( targetscore), additional if statements to light the LEDs depending on score, and some tweaks to the printlines to show the target next to their current score. Setting a target score Hold down that button whilst plugging in the USB cable into your computer’s USB port at the same time. You may see it pop up as a new device on your computer but just ignore that for now. A simple exercise first, using some of the code we learnt yesterday. We’re going to light each LED, wait 5 seconds, then turn them off. To do this we need to introduce a new module to you: time. Copy it over to Thonny and give it a whirl. We find that if you sit perfectly still, then wave your hands around, you should be able to test the program without having to leave the room! # Imports

Adding commentary makes explaining your code easier to others or even as a reminder to yourself when you return to a project a number of weeks or months later. It’s a very good habit to get in to and allows us to explain each line clearly:If you look at our Pico pin map again, you'll see that there are three dark green ADC pins available on the right - GPIO26, 27 and 28 ( physical pins 31,32 and 34). This year we have a brand new blinky-themed Let it Glow Maker Advent Calendar alongside the original 12 Projects of Codemas Maker Try this yourself, then try adding a fourth argument and printing a fourth line to go with it. The Code Just a Windows PC, Mac or Linux machine with a USB port (full-size USB-A port). The advent calendar gives you everything else you need each day. Our guides/Thonny will not work with Chromebooks. We’re going to install software called Thonny, which will allow us to program the Pico with MicroPython.

We also import sysin this example. The only reason we add this is to allow us to use sys.exit() to end the program after the game has finished. Most buttons are very simple, just connecting a circuit together which then sends a signal to our Raspberry Pi Pico via our chosen GPIO pin. You could do the same by simply touching two wires together, but of course buttons make this far more convenient and user friendly. elif (targetscore/ 100 * 33) < scorecounter < (targetscore / 100 * 66): # If our score is between 33% and 66% of the target For Maker Advent Calendar veterans - If you enjoyed the 12 Projects of Codemas last year, we think you're going to love the blinky theme of Let it Glow! With a whole new set of exciting components to add to your collection, including LEDs, displays and new control components, you can enjoy another fun festive season of coding and making. Everything you need is included

Activity 3: Multiple Button Inputs with elif and else

MicroPython is an smaller, more efficient version of the Python 3 programming language, designed to be used with microcontroller boards such as the Raspberry Pi Pico. If you've programmed with Python previously, MicroPython will feel very familiar - but don't worry - we're going to guide you every step of the way over the next 12 days. The frequencyhere changes the toneof the buzzer - we find that our ears can detect changes in the tone when using values between 10 and 10000. Thonny installs like most programs, and will ask you to accept the license agreement and confirm where to install it. We kept all the options as default and it took just under a minute to install.
