Re: Using the HC-SR04 ultrasonic receiver

The two while loops in that code need timeouts - they could cause the code to hang. Looks like code ported from Arduino.

Re: Thonny variables area missing

To see the variables window you need to switch to regular mode then select View, Variables.

Variables will only be shown when they are actually in memory. If you stop the program all variables will no longer be in memory hence disappear from the variables window.

Try the following, using Python and pygame 1.9.4. This version of pygame seems to treat the 2 screens as 1 large screen. You'll need to change 'DSC_0140.JPG' to your file. You may need to change your screen sizes: scrnRect = [pygame.Rect(0,0,1920,1080), pygame.Rect(1920,0,800,480)] Install pygame wi...

Re: how to filter certain values ​​from a list

Assuming Python this is one method:

Code: Select all

chars = ['1','2','2','2','3','4','5']

filtered = []

for char in chars:
    if char=='2':
        filtered.append(char)
        
print(filtered)
