PCB Etching Machine

PCB Etching Machine is used to slowly stir ferric Chloride acid so that the etching process to dissolve copper on the PCB occurs more quickly. Users can set the duration of this machine to work through the button and LCD provided. The microcontroller used in this project is PIC. We can change to whatever microcontroller that we want to make this project run.
