    CONTECSUL
    The circuit diagram shows a PIC16F877 microcontroller connected to 7 transistors through 4 74HC154 decoders. The microcontroller controls the transistors by sending signals to the decoders. A 4MHz crystal controls the clock for the microcontroller. Capacitors are used for decoupling.
