Pnp transistors are extremely versatile low cost switching solutions. They are durable, robust and reliable low power consumption electronic components. This circuit demonstrates the pnp's unique versatility when coupled with a logic source pad, a relay and three 7 segment displays.
The possibilities are endless...
Press the push button to switch on and off the 7 segment displays...(the 7 segment displays display the letters "pnp" as in ("pnp" transistor)
Enjoy...😎
