MAKERFACTORY 15045 Advent Calendar for Raspberry Pi

Product Information

You now have another sensor in your ever-growing box of bits to make projects with - perhaps you'll combine it with the PIR sensor from day #7 to make an awesome alarm with multiple sensors?

Once installed, select ‘Finish’ and then open the program. In Windows 10/11 you can select the Windows Start button and just type in ‘Thonny’. The program should open and look like the example below: We can tell our program to turn this pin on and off whenever we like, which is a nice easy first hardware project and can be handy as an indicator for your own projects later on. This is the beginning of getting your code to control physical things!wiring diagrams make this perfect for anyone wanting to get started with the Raspberry Pi Pico, programming and electronics. Let's get this sensor up and running with a minimal starter program. The code example below uses things we've covered in previous boxes so you should be quite comfortable with how it works. The Code 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 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.

That last activity included a lot of detail so we're going to leave it there for today and not overload your fresh coder brains! Now grab the mini breadboard and fit the potentiometer to the front edge (facing you). Our diagram uses a generic potentiometer image, however as you have a fancy panel mount version, your pins will have a hole space between them: You should now see a ‘Raspberry Pi Pico’ panel on the left-side of Thonny, and information in the bottom-right ' Shell' panel. Our code so far has been ON/OFF or HIGH/LOW using digital inputs and outputs. With today's component, we're going to explore analogue inputs which work in a different way.

The long leg is the Anode (+) and the short leg is the Cathode (-). Current must always flow from the anode to the cathode, so be sure to read our wiring instructions below carefully to make sure you get this bit right. Resistors How about a little festive tune with our buzzer? By changing the frequency between each pause we can create a tune that resembles a popular festive jingle!

Welcome to day four of your 12 Projects of Codemas Advent Calendar. Today we’ll be playing with analogue inputs using a potentiometer and combining this with some of the components we've already played with. The time module allows you to program delays in your code, making it wait for seconds or fractions of seconds before continuing. It’s another fundamental module you’ll use in most of your projects. The Code 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. Grab your potentiometer, slide the flat washer over the dial and then screw on the included nut (these may already be fitted).Welcome to day two of your 12 Projects of Codemas Advent Calendar. Today we’ll be playing with one of the most popular components for makers - LEDs! We use 0 to 33% f or the red LED, 33% to 66% for the amber LED, then any score over 66% lights the green LED. This gives our player a visual indication of how close they are to beating the game. Ifs in ifs?! 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. Now, get some rest and a good night’s sleep, for tomorrow we will continue the fun with day #2 (no spoilers here, and no peeking until the morning!).
