what resistor should I be using for these 12v 50mA momentary buttons for my Ar3

Hi,

what resistor should I be using for these 12v 50mA momentary buttons for my Arduino R3?

The 5 LED buttons will be outputting a High, Low value for Arduino R3 to recognize to control a Servo Motor.

Enviroment temperature:-25 to 85 degree
Relative humidity: 40 to 80 degree
Rating:DC12V, 50MA
Contact Resistance: less than 100ohms
Insulation resistance: more than 100ohms, DC250V/1MIN
Dielectric strength: AC250V 50HZ for 1 MIN
Electrically life:100,000 cycles
Mechanical life:100,000 cycles
Travel:0.25+or-0.1mm
Operating force:160+or-50GF
Dimensions: 12 x 12mm(L x W)
Color: Red, Green, Blue, White, Yellow
Mainly used in digital camera, industrial equipment, home appliances, etc.
Stable performance, safety and reliability

Package includes:

RED *1PCS new

White *1pcs new

Yellow *1pcs new

Green *1pcs new

Blue *1pcs new

This is an example Arduino code to use the read the button and execute the servo motor when button is pressed.

const int IButton = 10; //Idle speed button

pinMode(IButton, INPUT);

IBState = digitalRead(IButton); // read the state of the Idle pushbutton value

if (IBState == HIGH) { // run the Idle speed function
delay(250); // to debounce button
Idle(); // go to Idle function
}

My guess is I can use 10K ohm resistor as well as the Arduino R3 internal pull-up resistor too.

Rating:DC12V, 50MA This could imply there is already a resistor in the switch, BUT you will have to prove this.

Are you going to be using 12v?

Show us a good schematic of your proposed circuit. Show us a good image of your wiring.
