# What is a limit switch Arduino?

## What is a limit switch Arduino?

A Limit Switch is connected in series with a 10K ohm resistor. This is a Pull-Up resistor. In the same way, you can connect multiple limit switches. When the switch is closed it will connect ground with the digital pin 2 of the Arduino or Mega, or in simple words you can it will give 0 as the signal.

## When would you use a limit switch?

In electrical engineering a limit switch is a switch operated by the motion of a machine part or presence of an object. They are used for controlling machinery as part of a control system, as a safety interlocks, or to count objects passing a point.

## What do you need to know when selecting a limit switch?

When selecting a limit switch, consider the application and actuation method first, as often they are the clearer determining factors.” Being non-contact, and usually configured with a solid-state output, these devices work well for high-speed automation, but limit switches can also work well in similar applications.

## How many types of limit switches are there?

– There are 4 general types of limit switches: whisker, roller, lever, and plunger. – Limit switches are electromechanical devices operated by a physical force applied to it by an object.

## How is the limit switch connected to the Arduino?

This is a Pull-Up resistor. In the normal condition, 5 Volt is connected with the Arduino, but when the limit switch is pressed the ground is connected with the Arduino’s pin number 2. In the same way, you can connect multiple limit switches.

## What kind of resistor does the Arduino Uno use?

As you can see in the circuit diagram the limit switch wiring with the Arduino Uno or Mega is really simple. A Limit Switch is connected in series with a 10K ohm resistor. This is a Pull-Up resistor.

## Can a limit switch be used with a Raspberry Pi?

This limit switch can also be used with Mega, tinny, 8051 microcontrollers, pic microcontroller, plc, raspberry pi, etc. for the limit switch interfacing watch this Video Tutorial “ Click Here ” As you can see in the circuit diagram the limit switch wiring with the Arduino Uno or Mega is really simple.
