Of course, we can do more than just flash a single LED with transistors and capacitors. We can also get two LEDs flashing alternately.

Here, we will see what happens when you get two single transistor/capacitor combinations working together. The idea behind this circuit is to get each capacitor connected to a transistor to charge and discharge through their base, using the transistors as switches. The transistors will then switch the LEDs ON and OFF repeatedly.

let's see how it works.
