The code calculates the mean distance using 5 consecutive samples and also calculates the variance of those samples. If the mean distance is less than 30 cm and the variance is less than 2 cm^2, the PWM frequency should be 2 Hz, otherwise it should be 1 Hz. The variance helps filter out …

NettetIn bright light looking straight at it then 20Hz flicker would be barely noticable, in dark adapted corner 'of your eye' vision you can detect 60Hz - assuming the LED goes all the way off. Regular lamps don't cause flicker at 50/60Hz because the filament barely changes in brightnes during the cycle because it doesn't have time to cool. NettetStep 1: Materials Needed. Here's a list of what materials you need and where to get them: Note: I'm a big fan of Tayda Electronics, as their materials are very cheap and they usually post 15% off discounts on their Facebook Page. 1 x Breadboard. 1 x 12V 5A power supply.
