The mystery of Light Emitting Diodes explained. Basic how to use them, calculate resistor values, voltages, and amperage. LEDs can be tricky but are necessary when lighting your model railroad.

There are many sizes right down to almost microscopic! And many colors. BUT the current load must be considered and a proper load must be placed in the circuit.

SO let's dive in.
