FRANZIS 55103 Raspberry Pi Advent Calendar, Build and Program a Nativity Scene in 24 Days, Includes 52 Page Manual, No Soldering

Product Information

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 using Windows (11) in the example projects using the Thonny IDE. Thonny is also available for MAC and Linux machines and there should be very little difference from the instructions. Chromebooks are not supported. note = random.randint(100, 500) + int(newReading / 40) # noise chosen randomly + added pitch from the new reading We’ll tell the Pico to ‘ print’ some words ( known as a 'string' of text). These words/strings are then ' printed' to the Shell window. The print function is something you’ll use a LOT when programming. It’s a useful tool to see what’s happening with a program, what part of a program is running and can help when debugging projects. Imagine you’re bouncing a ball whilst your friend counts how many bounces you’ve completed. Your condition might be “ bounce the ball until you count five bounces”. After five bounces, you would stop.

For those who want to get technical - the Pico's ADC pins are 12-bit, however MicroPython scales this to a 16-bit range which is 0-65535).Now grab the jumper wires. You need one wire connecting the blue channel to a Ground pin on your Pico – we suggest using physical pin 38 like we’ve done in the diagram below (remember to refer to the Pico pinout if you need a reminder). Give it a spin by copying the code below over to Thonny, running it on your Pico and moving the dial left to right slowly. Remember, the code commentary is there to help you understand each line: # Imports Whilst we only use the delay once in the example below, we thought it was still a nice opportunity to show you another way of using variables to save you time and improve your code. The Code Our buzzer can generate different tones based on the PWM frequency and duty cycle we use in our code - this should sound familiar as we covered PWM yesterday. PWM Frequency and Duty Cycle with Buzzers Both calendars include a Raspberry Pi® Pico H and assume no prior knowledge of coding or electronics - so they're great for

Maybe we want to ignore buttons 2 and 3 if button 1 is pressed? Do we want something else to happen if none of the buttons are pressed? Perhaps we want something to happen if we hold two buttons down at the same time?something blinky and something to control your light-up components - think sensors, sliders and more... This year we have two calendars to choose from. The contents are different but the style and learning approach are the same. The example below is purposely inefficient and uses a LOT of lines, mostly because each section of the jingle includes lines to turn the volume on then off as well as delays. Try this first, then we'll move on to a nicer way of doing things in the next activity. Tip: If you don't see your Pico on the left, try selecting 'View' from the top navigation bar, and selecting 'Files'. After that it’s a simple case of setting each LED pin HIGH, waiting for 5 seconds using time.sleep(5), then setting them all LOWagain.

As always, please do not disassemble the circuit until tomorrow where we will explore the next fun component - see you then!The right pin needs to connect to the 3V3(OUT) pin ( physical pin 36), the middle pin to GPIO 27 ( physical pin 32) and the left pin to GND (use the blue lane as we already have that connected to GND for the LEDs). This twelve-day advent calendar will teach you how to code with MicroPython using a Raspberry Pi Pico, using software along with a selection of fun, popular components along the way. We’re going to use code to make hardware interact with the real world!

The else statement says " if none of the statements above have their conditions met, do this instead". It can be useful if you want something to always happen when none of the above if/elif statements are being met. Everything else you will need for each project is included in each day’s box, and the required software (Thonny) is free. No soldering required! Spoiler Alert! With the first day’s box giving you a new pre-soldered Raspberry Pi Pico H, Micro-USB cable and a couple of breadboards, all you need is a compatible computer (with a full-size USB port) to plug it into - a Windows PC, Mac or Linux machine (sorry, Chromebooks are not suitable). We can do many of these things, and more, by using our if statement with additional statements elif and else. Let's explain how they work before we try them: The elif statement So far we’ve relied purely on code to tell our components and program what to do and when. Now we’re going to use physical buttons to do that, which will act as triggers in our program to determine what happens.

Here's another simple example just to show you how easy it is to change the tone on your buzzer from one to another. So why is this better? Let's look at two examples below where we want to print a set of strings three times. Both of the following examples have the exact same outcome (try them yourself) however the code using functions is shorter. Now try changing that frequency number to 300 and see what happens. Did the tone go lower? You can try higher values too, but eventually you’ll go too high (around 10000) and it won’t work/your human ears won’t hear it. Activity 2: Changing tones Something different you'll spot next is where we wait for the sensor to settle or 'warm up' before jumping into our while loop. Warm Up Please hold the sensor at the edges of the green PCB when fitting as it is a delicate component! Important! Sensor Orientation!
