ROBOTICS

• Resistors


  • Electronic components that limit the current with some value of resistance
  • Resistance blocks the flow of electricity
  • The bigger the value of resistance, the little flow of electricity and vice versa
  • Passive components that only consume power (and cannot generate it)
  • Commonly used to limit current, divide voltage, and pull-up I/O lines
• Resistors color code


  • Green
  • Brown
  • Red
  • White
  • Violet
  • Orange
• Lesson 1 Resistors

  1. How to calculate the value of resistors: Digit, Digit, Multiplier = Color, Color x 10 Color in Ohm’s (Ω)

  2. For example, a resistor has the following colored markings: 3 band resistor

  3. For example, a resistor has the following colored markings: 4 band resistor, Digit, Digit, Multiplier, Tolerance = Color, Color x 10 color in Ohm’s (Ω), % tolerance
• Breadboard


  Used to create circuits and connect different sensors and actuators to the Arduino board, also refers to a solderless breadboard
• Project: Basic Connection with LED and Resistor Lesson 2


  1. Build few simple LED Circuits

  2. Investing more in LEDs due to their energy efficiency in home lighting and offices
• Project: Basic Connection with LED and Resistor


  Building simple LED Circuits using Arduino and controlling LEDs
• People are investing more in LEDs due to their energy efficiency for home lighting, office lighting, automobile lighting, street lighting, etc.
• Students will learn how to use an Arduino and control LEDs in this project
• Using an LED without a series resistor can damage the LED
• An LED will survive the experience if there is a series resistor of at least 100 ohms next to it
• Always use a resistor when working with LEDs, a 1.0K ohm resistor is a good place to start
• Using an LED without a series resistor is a sure-fire way to damage it
• Not using a resistor with an LED may cause a bright flash and the LED may turn dark
• A 1.0K ohm resistor is recommended to be used with LEDs
• Parallel Circuit Connection


  electrical connection that has two or more paths for the current to flow in which the loads are parallel to each other
• Series Circuit Connection


  electrical connection that is connected along a single path where the current flows in the same direction
• Switch Circuit Connection


  electrical connection which is installed on one path that allows or disallows the flow of current to a device from the source
• Light Emitting Diode (LED)


  a semiconductor diode that converts electric energy into electromagnetic radiation at a visible and near infrared frequences when its pn junction is forward biased,
• LED

  1. Short pin to be connected to GND (ground)
  2. Longer pin to be connected to any of the digital pins (pins 2-13)
