If your Arduino is plugged into a USB port two Other times you want only a little because you are driving a small LED. Sometimes you want a lot of current because you are driving a motor. Sometimes you want a little water toįlow to air, as in a water fountain. Sometimes you want a lot of water toįlow to air, as in a fire hose. Pipe somewhere this will slow the water and less water will flow out of You have a high pressure source and a wide pipe then a lot of water To air, this is a bit like a circuit that is connected to ground. A common metaphor forĮlectrical current is water in pipes. If you haveĪ source with a lot of available power this results in heat which mayīurn you or melt and ruin electrical components. When you complete a circuit that has no resistance, current willįlow through it as fast as the power source can provide it. Resistors are designed specifically for that purpose. Resistors reduce the flow of electricity, or current, in a circuit.Īll electrical components resist to some degree, even wires, but Unlike the LED and some other electronics components, resistors canīe connected in any direction - they don't have positive and negative 2.2 ResistorsĪre one of the most common electronic components so let's explore how Learn a bit about resistors so we know why they are used, and can pick The resistor might be a bit trickierīecause resistors are labeled with stripes instead of numbers. LEDs are the lights in your kit, and a red one should be easy This circuit calls for two pieces of hardware in addition to the Arduino, a red LED and a 560Ω

If we want to use the Arduino to control the light, we can modify the above schematic diagram to the following: In your class, you have been discussing a basic circuit that has the following components (circled in pale red):

So you don't have to solder things together, you will temporarilyīuild your lab circuits on the breadboard provided with your ARDX kitĪnd change the code to modify how the device responds. We will then examine the code that makes the LED blink.Īt the end of this lab, you will make the LED blink Morse Code-all through the magic of code! The focus of this lab will be on building a basic circuit with an LED. It responds by changing the code (instead of changing the hardware). Of using the Arduino is that we can build a circuit and then modify how

The KY-011 should alternate color every one-second.CS207: Introduction to Mac and Arduino Lab 2: Blinking LightĪs mentioned earlier, Arduino consists of two major parts: the PinMode(9, OUTPUT) // module's green pinĭigitalWrite(9, HIGH) // switch on greenĭigitalWrite(9, LOW) // switch off greenĪpply power to your Arduino Uno board. Save the code as KY-011.ino and upload it to your Arduino board. I have added comments to explain important parts of the code. The KY-011 module pins are connected to the Arduino Uno board as follows: Component Pinīelow is the Arduino sketch for our project. The two 220-ohm resistors are needed between the Arduino and the Green and Red pins of the KY-011 to protect the LED from over-current. Project Componentsįor this project, we need the following components:įigure 2 shows the connection between the Arduino Uno and the KY-011 2 Colour LED Module. Our project will alternate the color (red/green) of the LED every one-second. Project: Arduino 2-colour BlinkerĪfter learning about the KY-011 module and the 2-colour LED, it is now time to build a project using the module. Component PinĪ 2-color LED is simply two different colored LED’s assembled in one package. Figure 1: KY-011 2 Colour LED Module Pin Out: Figure 1 shows the module as seen in fritzing. This module has a 2-color LED mounted on a breakout board.

The KY-011 Module will be our main component for this tutorial. In this tutorial, we will learn about the KY-011 module, what is a 2-color LED and we will build a simple 2-color blinker using an Arduino and the KY-011 module.
