Pin Indicator Simulation with 2 LEDs and Transistors

00:32:11

Pin indicator for current direction. The source on the left is a model of the pin turning ON and OFF. The 5V is provided by the USB 5V. The LEDs alternate turning ON and OFF based on the flow of the current. This solution is non intrusive to the Adafruit Playground, meaning, we are not subtracting from the maximum current from the LED pin.
