Arduino Resistor Color Codes Explained: What Each Means

Leave a comment

As defined by Arduino to Go, every shade band on the resistor corresponds to a quantity however this could differ relying on the band’s placement. It’s not difficult, however the sheer variety of colours and the way their placement can have an effect on a resistor’s Ohm worth makes making an attempt to memorize every part considerably difficult. In essence (once more, relying on placement):

  1. Brown is one, or a multiplier of 10.
  2. Red is 2, or a multiplier of 100.
  3. Orange is three, or a 1,000 multiplier.
  4. Yellow is 4, or a multiplier of 10,000.
  5. Green is 5, or a multiplier of 100,000.
  6. Blue is six, or a 1,000,000 multiplier.
  7. Purple is seven, however has no multiplier.
  8. Grey is eight, additionally with no multiplier.
  9. White is 9, no multiplier.
  10. Black is a zero, or a multiplier of 1.

Silver and gold are the 2 exceptions to this sample in that they do not signify a quantity or multiplier. Instead, they point out a 10- to 5-percent (respectively) vary in accuracy — that means a gold band resistor may have a 5-percent greater or decrease Ohms worth attributable to attainable variance within the manufacturing course of.

6 Easy Arduino Projects For Beginner Coders

Probably one of many coolest Arduino projects out there’s a remote-controlled automotive, however they’re additionally one of the daunting initiatives for learners to undertake. However, you will be glad to know that there are RC automotive variations that do not require being a coding skilled.

This Bluetooth-controlled car could appear too formidable for a newbie mission at first look, however it’s really a straightforward construct. It’s run by an Arduino UNO board, and contains a number of key elements: 4 gear motors with wheels for transferring the automotive, 4 LEDs for signaling the lively standing of every motor, a motor driver for working all of the motors, a Bluetooth module for distant management, and a battery for powering the automotive. 

Upon powering up, the automotive routinely turns into seen to exterior Bluetooth gadgets like your telephone. You can then join it to your system utilizing the project developer’s Android app, and begin controlling the automotive with the joystick. Press one course, and the motors for that individual course shall be activated. The LEDs linked to these motors will even gentle as much as present which of them are in motion.

Unlike the opposite initiatives on this checklist, the code for this setup is a bit over 100 traces, however it’s a superb introduction to working with customized capabilities that may be known as inside different capabilities, just like the loop operate. You typically would not want to change something within the code, besides maybe to vary the pin configuration of the motors in the event that they occur to run reverse to your command.
