You’ll receive a different project component every day including any required wires/resistors/accessories etc. If you want to see what's inside, a list of the contents can be found here.

Place a resistor between the left leg of each LED and the lower blue channel, like below. We'll be connecting that blue channel to a Ground (-) pin shortly. The code below uses the readings to control how fast your LEDs flash. We do this by making a time delay variable. Variables for Time DelayImports bring in code from other places (called 'modules' or 'classes' - but let's not get bogged down with that for now) that we need to make our program work. Usually these are from built-in modules.

The Raspberry Pi Pico is a powerful, flexible microcontroller board from, you guessed it, Raspberry Pi - the same folks who brought us the Raspberry Pi 4 and Raspberry Pi Zero. Welcome to day five of your 12 Projects of Codemas Advent Calendar. Today we’ll be making sounds with our code using the custom buzzer you've just discovered in your box! In the example below, in each while loop we take a reading from the potentiometer and store it in a variable called 'reading' (just like we did yesterday in activity 3) and then we use this variable as the buzzer duty value (instead of adding a number there ourselves). Copy that code to your top-right panel, then hit the run button. The LED should light up – hooray – you’ve controlled your first physical component!PWM stands for Pulse Width Modulation. It's a type of digital signal where we, over a set period of time, decide how long the signal is ON (HIGH) and how long it's OFF (LOW). If statements can be very powerful and there are lots of different and advanced ways to use them. You'll use them lots when making your own code. We'll start with a nice simple example, but first let's explain something else new in our code - pull downs. Pull downs
