About this kit:

This Kepler kit applies to the Raspberry Pi Pico W. It includes various components and chips that can help to create various interesting phenomena which you can get via some operation with the guidance of experiment instructions. In this process, you can learn some basic knowledge about programming. Also you can explore more application by yourself. Now go for it!

kepler-kit's Issues

Project 2.4 Colorful light - Orange? Negative...

I found that this program works fine in terms of execution. However based on the values set in the example and the document which shows that red at 255 and green at 128 with blue at 0 gives you orange.
https://docs.sunfounder.com/projects/kepler-kit/en/latest/pyproject/py_rgb.html

I've messed around with the inputs, I can get a solid green, red or blue by setting them to 255,0,0 0,255,0 0,0,255 ect..
I'm using the right resistors, verified using my bench top DMM, the resistances are all within tolerances.

The color given off by running this example is more of a greenish/yellowish color, nothing even close to the documentation (orange). I found if i set things to 255,10,0 then I get something that looks more like Orange.

I tried using one of my own CC RGB LED's same result.
While I'm new to Micropython, I am not new to Pico programming, I have made many complex programs with pure C (not Arduino) and the SDK in VSC,

This is more of either a correction that needs to be made in the training documentation. If someone is using this kit that has zero experience to any programming and Pico/W this example would leave them wondering what they did wrong because they are not getting an orange like the documentation.

For the sake of sanity because I'm human and prone to errors I even tried a copy paste of the code from github. No change. My handwritten code matches 100%.

I thought it was quality control on the LED, but as I stated I tried my own that are of higher quality and all result in this greenish yellow color that does not look Orange. Maybe edit the code to have the user try, just red, then just green, and then just blue. Then let them mix them on their own with no expectation of an Orange at 255,128,0

Anyways just a thought. Trying to help when I can. The documentation shows a nice Orange for 255,128,0 which is NOT the case at all. So far the Kepler kit has been great no issues. Very similar components and projects that I purchased from a different vendor to learn pure C. I love C programming and its speed but boy MP makes life so much easier for writing code hence I came to the dark side! Mostly for the Wifi. Wifi in pure C is rough...oof.

lcd1602.py does not initialize

Using the code provided in https://docs.sunfounder.com/projects/kepler-kit/en/latest/pyproject/py_lcd.html

The library fails to initialize:
Traceback (most recent call last):
File "", line 4, in
File "lcd1602.py", line 12, in init
File "lcd1602.py", line 35, in send_command
File "lcd1602.py", line 29, in write_word
OSError: [Errno 5] EIO

[SOLVED] 7.4 Passenger Counter just displays 8888

UPDATE: I simply needed to wiggle my GPIO wires to the HC595 and it suddenly began working. I guess it was just a weak/faulty breadboard socket!

The PIR sensor works terrible though, I toyed with adjusting the tuning dials etc and cannot get anything close to a reliable "passenger counter". It detects a person's movement about 1:5 times, and after a detection, its like the PIR goes to sleep for 60 seconds and won't detect anything that whole time.

---

I double checked all my wiring and can't find any errors. If I had errors it wouldn't be able to light up all 8888. Why doesn't it display 0?

When I move in front of the PIR sensor, nothing happens. But if I uncomment the print(count), that does occasionally increment.

I turned both dials clockwise as indicated.

Running code directly from kepler-kit-main.zip.

I noticed clearDisplay() is never called in the code?
