In this project we will make a PCB of a shield button for programming tests using the ladder language for PLC.
We will use the PULL UP and PULL DOWN configuration to send signals like NO and NC to the ARDUINO UNO and we will use the LDMICRO software to program it using the LADDER language.
Ladder language, ladder diagram, contact logic/diagram, or ladder diagram, is a very popular graphical programming language within programmable logic controllers because it is based on classic control electrical diagrams. In this way, with the knowledge that every electrical technician or engineer possesses, it is very easy to adapt to programming in this type of language.
Ladder is one of several programming languages for programmable logic controllers (PLCs) standardized with IEC
t is a ladder language programming software for microcontrollers (ARDUINO UNO, MEGA, NANO and other pic microcontrollers) where we can generate the ARDUINO IDE or HEX file to burn or pass the code to our microcontroller.
