For such cases we use serial to parallel converter chips or shift register. A shift register chip takes data from UNO board serially and gives output in 8 bit parallel configuration. Components ...

To do so, the Arduino was set up to monitor the BUSY line on the printer’s parallel port, setting the CTS line active whenever the busy line was inactive. With our task made clear, hours of ...

Abstract: This paper contains the information of a CNC milling machine firmware development for PCB manufacturing, using an Arduino UNO board to control, with a USB connectivity between the machine ...
