Data Entry from the Screen,eries with the diode, power source, and ground. The current through the LED can be regulated by varying the voltage of the supply. However, diode intensity control by voltage variation can only be effective above the voltage level required for conduction in the device, typically 1.8–3 volts.

Graphical Data Recording,th x-y and x vs. time plotting systems are extensively employed in the manufacturing process industries, chemical analysis, and other sciences, the electro-mechanical plotting instruments, much like the typewriter, have been replaced by the PC.

https://doi.org/10.1007/978-1-61779-767-5e state of the system is determined visually, by whether or not the LED is illuminated. As the initial exercise in interfacing the SCADA software with the HMI and the breadboard electronics, the ability to control the application of power to simple electronic circuits from a display screen or keyboard is demonstrated.

Kane Greer,Sue Fletcher,Steve D. Wiltonto develop the use of binary numbering and digital electronics, utilizing the standard 0- and +5-volt signal levels as the representations of binary ones and zeros. In many surface mount technology (SMT) devices, the logic levels are 0 and 3.3 V, and the SMT integrated circuits are often damaged by inadvertent application of 5 V signals.

Merryl Rodrigues,Toshifumi Yokotart of SCADA systems. The DAQFactory software provides variable control icons such as rotating knobs or moveable sliders. The knob or slider page components can be coupled to an analog output channel whose value will be proportional to the rotating position of the control knob or the linear position of the slider index marker.
