📄️ Conditional Statements and Loops
This lesson will introduce you to more programming structures which are essential to learn about.
📄️ The Serial Monitor
The serial monitor is a tool within the Arduino IDE which we can use to communicate to and from the Arduino board. The serial monitor is especially useful when debugging and testing out different components to ensure they are functioning as expected.
📄️ Understanding PWM
Until now, we have learnt how to turn an LED either fully on (by supplying 5V), or off (by supplying 0V). Pulse Width Modulation (PWM) is useful in many different applications, but for now, just remember it can be used to vary the brightness of an LED.
📄️ The RGB LED
An RGB (Red-Green-Blue) LED is is like 3 LEDs in one. We can use an RGB LED to produce a variety of colors by mixing different intensities of red, green and blue light. Search up RGB LED online to understand what one looks like.
📄️ Project: Mood Light
Projects are intended to consolidate the knowledge you have absorbed in previous lessons. This one will help you apply what you've learned about the RGB LED.
