7-segment displays are extremely versatile and are widely used in digital clocks, electronic meters, basic calculators, and other electronic devices that display numerical information. This circuit is a good example of their application, in this example a flashing mini bill board courtesy of the 555 timer.
The resistor connected to pin 2 & 7 determines the flashing rate.
Touch logic source pad to initiate and end circuit flasher sequence.
