| The resistor controls the blinking speed because, the resistor controls speed the capacitor charges at. If the charging of capacitor slows down, the LED will need more time before it can turn on. I can add resistance by adding a resistor with greater resistance and doing that would slow down the current. To change the amount of resistance without swapping out parts, I can use a potentiometer. | The resistor controls the blinking speed because, the resistor controls speed the capacitor charges at.
