Put the three zeros after the first two digits and we get 10,000 or 10k. Orange has a value of 3, which means three zeros. This means that the resistor value starts with 10. 10k Resistor Colors and ValuesĪs the above image shows, the resistor brown band has a value of 1 and black a value of 0. 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.
