Web6 de mai. de 2024 · Vout = Vin * R2/ (R1+R2) where R1 is the resistance between Vin and Vout, and R2 is the resistance between Vout and Ground. If the knob is halfway, then R1 = R2, so the equation simplifies: Vout = Vin * R1/ (R1+R1) so with 5K: Vout = 5V * 2500/ (2500+2500) = 2.5V. and with10K Vout = 5V * 5000/ (5000+5000) = 2.5V. WebSince we have our readings, we need a way to convert it to a brightness value for the LED. By using analogWrite (pin, value) we can tell the LED how bright to be. analogWrite only works on pins 3, 5, 6, 9, 10, and 11 on the Arduino Uno so make sure your LED is connected to one of these pins. These pins are indicated by a squiggle line next to ...
