How to Control LEDs on the Arduino - Circuit Basics
WebJan 12, 2016 · 1. I wanted to control an LED using a transistor (my first attempt at using a transistor). I connected a transistor (TL188) to pin 13 of an Arduino Uno accidentally and noticed something. (The resistor I … WebMar 10, 2024 · This will give a smooth brightness change: y = a * exp (-b * x * x); // x is incrementing in time. If you really need a very smooth brightness change for a normal led, you might need an extra output with a higher resistor value to the same led, for a higher resolution at low brightness. Share.
