This picture shows the use of one type Atarado SMART prototyping PCB with assembly of PWM controller on the board.
Active electronic components that are used within the board are NE555 and MOSFET IRF540. Potentiometer is for adjusting duty cycle of pulse-width modulation.
There's no rush on the top of the PCB and components with wire jumpers are taking a very little place of 53x33mm board, and it's capable of much more complicated schematic to be implemented due to vast combinations of PCB layout.
