Notice that both 2200K ohm resistors are connected to the same terminal on the potentiometer, which allows it to control the speed of both lights. {{:astable-led-01.jpg?400|}} {{:astable-led-02.jpg?400|}} {{:astable-led-03.jpg?400|}} {{:astable-led-04.jpg?400|}} led-oscillator.txt Last modified: 2 years agoby renick Log In
