Learning Resources TechFactors Copyright 2020 Resistors RESISTORS are 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. They are passive components, meaning they only consume power (and cannot generate it). Commonly resistors are used to limit current, divide voltage, and pull-up I/O lines.​ TechFactors Copyright 2020 Resistors TechFactors Copyright 2020 Resistors TechFactors Copyright 2020 Resistors Significant figure Tolerance Multiplier Green None Brown Brown Red Green White Violet Orange Violet TechFactors Copyright 2020 Resistors How to calculate the value of resistors?

You need to design a system where one switch can turn on multiple lights! An example might be a string of holiday lights. Now, construct both a series circuit and a parallel circuit using the batteries, wires, and bulbs provided to you. Your series circuit will look something like the drawing below: TechFactors Copyright 2020 Circuits TechFactors Copyright 2020 Circuits TechFactors Copyright 2020 Circuits TechFactors Copyright 2020 LED TechFactors Copyright 2020 Project: Basic Connection with LED and Resistor Project: Basic Connection with LED and Resistor In this lesson, we will build few simple LED Circuits. Nowadays, people are investing more in LEDs due to their energy efficiency. Home lighting, office lighting, Automobile lighting, Street lighting etc. are all being implemented using LED. In this lesson, students will know how to use an Arduino and to control LEDs. This is a pretty simple project, but you will learn how to do it early on because lots of other sensors and modules are programmed the exact same way.​ TechFactors Copyright 2020 Project: Basic Connection with LED and Resistor Target Outcomes: At the end of the discussion, the students should be able to: ❑ Build and key in the code based on the circuit diagram.

While LEDs will not work when placed backwards, you don't have to worry about whether it will be damaged: as long as there is a series resistor of at least 100 ohms next to it, the LED will survive the experience! However, using an LED without a series resistor is a sure- fire way to kill it! (You'll see a bright flash and it may turn dark) Always use a resistor! A 1.0K ohm is a good place to start. We'll cover how to figure out the best resistor value later on. TechFactors Copyright 2020 Project: Basic Connection with LED and Resistor TechFactors Copyright 2020 THANK YOU!
