Like our larger breadboard, that central channel disconnects one side from the other, which is handy when wiring projects otherwise all of our button legs would be connected together ( and we really don't want any magic blue smoke!). The example below includes the same ingredients you're now becoming familiar with - imports, pin setup (with PWM), PWM duty cycle and frequency - so there's nothing new or scary here, and our usual slightly-excessive code commentary tells you what each line is doing!
Today we’re going to get you set-up and familiar with the Raspberry Pi Pico, including installing the software required to program the board as well a running a couple of very easy projects to get to grips with MicroPython. Introducing the Raspberry Pi Pico note = random.randint(100, 500) + int(newReading / 40) # noise chosen randomly + added pitch from the new reading To make our if statement look for a value ' between' two numbers, we use a slightly less-obvious combination of two < operators, like this: if 20000 < reading < 40000
Nope! The projects can be made all year round, and the online instructions for each day will remain available for as long as we exist! We can decide how long we keep our LEDs ON/HIGH by changing the Duty Cycle. The duty cycle is the percentage of the time that our LED will be ON. The higher the duty cycle, the longer the LED will be ON, and the brighter our LED will appear.
We know that 12 days isn't technically advent, but we think it instantly helps to describe the intention for this product (if we If you're curious, try the very short code below to see what epoch currently looks like: import time
Today’s Project
something blinky and something to control your light-up components - think sensors, sliders and more... This year we have a brand new blinky-themed Let it Glow Maker Advent Calendar alongside the original 12 Projects of Codemas Maker Place the three LEDs into the lower section of the breadboard, 1 hole apart, with the longest leg to the right as seen in the image below.
The first line imports ‘ Pin’ from the ' machine' module on the first line, which simply allows us to use the GPIO pins.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. Imports 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.
Turn your knob to around half-way to start with, run the code below, then try adding in the other LEDs and making them flash as well, or try adding a print line at the end of the while loop to see what value mydelayis using: # Imports 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:This leaves plenty of time for customers to receive their calendars in time for the 1st December start date. 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
