A 5% tolerance 10k resistor has the colors brown, black and orange, as shown in the image below. The letter k in 10k is short for kilo which means 1000. Get a 10k ResistorĪ 10k resistor has a value of 10,000 ohms. Find the same information for Arduino MEGA 2560 boards in the Ultimate Arduino MEGA 2560 Hardware Manual. Although a 10k resistor is specified, any resistor from around 4k7 to 20k works in the circuit.įor more information on pull-up resistors, pull-down resistors, and other Arduino input pin configurations, see the Ultimate Arduino Uno Hardware Manual for Arduino Uno boards. In fact a 10k resistor is used in the circuit. Pull-down describes the function of the resistor in the circuit, it is not a special type of resistor. In this tutorial, a pull-down resistor is used in conjunction with the push button switch. There is more than one way to connect a push button switch to an Arduino.

Momentary Push Button Switches How to Connect a Push Button Switch to an Arduino Connect the wire link to the breadboard circuit to simulate closing the switch, and disconnect the wire link to simulate opening the switch. Use a wire link instead if you do not have a push button switch. The image below shows examples of this type of switch. When the switch is released, the contacts open. Momentary means that the switch stays closed only while pushed. A push button switch called a momentary push button switch is used in this tutorial.
