In PLC programming, the physical contact of the stop button is generally connected as normally closed, while in the program, it is written as normally open. This type of stop button only serves as a signal in this equipment.Why is the emergency stop in PLC programming opposite to that of a regular emergency stop button? … Read more
Overview This chapter will introduce the four basic processes used in wafer manufacturing to form electrical components of integrated circuits on the surface and within the wafer. The circuit design process traces from functional diagrams to the production of photomasks and mask plates. The characteristics and terminology of wafers and chips are described in detail. … Read more
The microcontroller is the core component of embedded systems, and circuits using microcontrollers are much more complex. However, when modifying and adding new features, circuits with microcontrollers are easier to implement, which is why electronic devices use microcontrollers. So, what are the challenges to pay attention to in the design of microcontroller circuits? 1. Selection … Read more
