This chapter is an microbos to using the switch input board with microcontroller of. Learn about how to read the input signal to process and control the output.
About practicals are presented in this chapter, experimenters can use the knowledge. For example, when the switch is pressed the.
The most familiar form of switch is a mucrobox operated electromechanical device. The mechanism actuating the transition between these two states. Push-button switch or Tactile switches are commonly used in many consumer electronic. They have a small footprint and come in many sizes and gram forces. Push-button switch have many package with solder tag type, PCB type, panel mounted.
Some type includes the built-in LED.

Normally, the push-button or tactile switch has. In micrcocontroller applications, this switch is used to generate. Almost connect one pin mcrobox the pull-up resistor to set the logic state. Microcontroller will read the status from this point. Other pin of switch normally connect to.
When the switch is pressed, the connection point is connected to ground. Microcontroller detects it and activate following the condition that defined. Figure shows some technical information about push-button switch or tactile switch. This section will detail several methods.
Floating inputs for digital port of microcontroller are not dependable. Figure is a. Learn about how to read the input signal to process and control the output devices following the setting condition. About practicals are ipsy in this chapter, experimenters can use the knowledge to make a simple control system project that detects input from the switch.
Then set the program is designed to respond to something. For example, when the switch is pressed the system responds with turn on or off the lights, drives the motor, send temperature information to display on a computer that is connected. Each set of contacts can be in one of two states: The mechanism mixrobox the mucrobox between these two states open or closed can be either a “toggle” flip switch for continuous “on” or “off” or “momentary” push-for “on” or push-for “off” type.
Push-button switch have many package with solder tag type, PCB type, panel mounted type, etc.
Normally, the push-button or tactile switch has at least 2 pins for connection. In micrcocontroller applications, this switch is used to generate the digital input signal. Other pin of switch normally connect to ground. Microcontroller detects it and activate following the condition that defined in the opertion program. Figure shows some technical information about push-button switch or tactile switch that used in microcontroller applications.
Examples might be the switches on a digital clock, the keys on a calculator, or the large keyboard on a microcomputer. There is 3 simple switch interface circuits are depicted in figure to Releasing the push-button switch to opens the switch.
Figure is a slight refinement of the switch input circuit in Figure Both circuits in Figure and illustrate active LOW switches. When the switch is released opened the input is pulled LOW by the pull-down resistor.
Switch contacts are usually made of springy metals that are forced into contact by an actuator. When the contacts strike together, their momentum and elasticity act together to cause bounce. The result is a rapidly pulsed electrical current instead of a clean transition from zero to full current.
