It doesn't matter which side of the LED the resistor sits , as long as it's there limiting the flow of current for the entire circuit ( take a look at the comment section for an example ). Raspberry Pi Pico Pin Map

Showing sensor readings on your OLED is quite possibly one of the most useful and fun ways to put the display to good use.This leaves plenty of time for customers to receive their calendars in time for the 1st December start date. First, make sure your Pico is disconnected from the USB cable. You should always do this when amending a circuit. Then grab the set of jumper wires, resistors and LEDs. Breadboards

Copy the code below over to Thonny and give it a try, then see if you can beat some of our staff record times below (the only rule is that only a single finger can be used). It's a great little game to set up over the festive period to challenge family and friends, and you get to show off your new kit and skills too!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. We've only just scratched the surface on what's possible with this fantastic little microcontroller and the components you've discovered over the last 12 days - there's so much more to learn and experience! Our final example adds the % symbol after the reading. We do this by adding some parts to our print line. Nope! Everything in the calendar is either pre-wired or uses jumper wires, and the Pico H has headers pre-soldered, ready to push into the breadboard. 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?

Today's a BIG one! We're going to learn how to light up the LEDs in our strip individually, how to code different colours and colour lists, how to create a light chaser, then a light chaser speed-controller using our potentiometer from day #4, some button colour control then fading effects - PHEW! You'll notice there are some arguments ( 0,0) after the text we push to the display: display.text("Hello World!",0,0) We have to tell MicroPython that we're using a 1-wire DS18B20sensor with the following line in our code below: sensor = ds18x20.DS18X20(onewire.OneWire(SensorPin)) Each day we’ll show you how to use the fun things you find in each box, explaining what they are, what they do, how to construct the circuit and then how to code them with MicroPython using simple methods. Our example below uses all of our usual ingredients (imports, display setup, button pins...) and creates a state variable, which we've used before. We use this variable to switch between the two if statements within our while loop. But why do we want to do that?Let's go one step further, adding more lines and changing the position of the text, but first let's cover those arguments... Arguments

We're going to take the example above (activity 2) and add variables for five different colours. We can then use these colours in our LED strip code to easily change the colour by just using the colour's name - such as strip[i] = (red). Whilst this can vary wildly as young children develop at different speeds, we think age 7 upwards is a safe starting point. And you’re never too old to learn something new! I am way behind the pace here because I got this as a Christmas gift and I am now working my way through. I’m having immense fun and learning a huge amount. Here is the code for a different game using the same sensors. It is a Formula 1 start time reaction game, for the F1 fans out there.

Our code imports pinagain, and also imports time. We then define the pin number for each colour of LED (giving them a sensible name for each) and set them to outputs. We use str(lightpercent) to convert our light value reading to a string, then add another string next to this with +"%". You can see this in the example below - give it a try: # Imports Welcome to day eleven of your 12 Projects of Codemas Advent Calendar. Today we're playing with a really fun and useful component that you'll use again and again in your projects - a mini I2C OLED display! A good starting place for inspiration and a great community is the Raspberry Pi forum, specifically the Pico section. Just don't forget to always search before asking a question! That's all Folks!
