WebDec 1, 2024 · The way we do this is by taking advantage of a basic electronic property of resistors and capacitors. It turns out that if you take a capacitor that is initially storing no voltage, and then connect it to power (like 3.3V) through a resistor, it will charge up to the power voltage slowly. The bigger the resistor, the slower it is. WebLearn at SparkFun Electronics - learn.sparkfun.com gloria horn studio classes
