Arduino boards are equipped with digital and analog input/output pins that allow users to interact with sensors, motors, lights, displays, and other electronic devices. This flexibility enables users to create interactive projects such as robots, home automation systems, wearable devices, and art ins...
LEDs are small, powerful lights that are used in many different applications. To start, we will work on blinking an LED, the Hello World of microcontrollers. It is as simple as turning a light on and off. Establishing this important baseline will give you a solid foundation as we work ...
This code first sets up the RGB-led pins via the variablesredPin,greenPin, andbluePin. Change these if you are using different pins than in the example circuit. Then, the code lights up the RGB LED with the colors red, green, blue, yellow, cyan, magenta, orange, purple, and white, ...
It’s now time to write some code to bring our lights to life. If you have programming experience, then you will find this code really basic. If you’re new to programming, then this is a great way to start learning all the basics. ...
Chapter 3 Controllable LightsRGD LED is actually just one category of LED lights. What makes it unique is that while common LED emits a single shade of white li...
Arduino UNO LED lights with half-brightness This is because the Arduino is fast. Very fast. Faster than the human eye. As a matter of fact, the LED actually blinks. It blinks so fast that you will neither see the LED on or off. You will see the average of this. Since the LED is...

In the previous project, we learned how to use buttons to control LED lights. Next, we will further apply the conditional statement structure to learn how to make simple timer lights. Task Navigation 1. What is a conditional statement structure?
8: Error - Lights up if something goes wrong (use red if that makes sense) 7: Programming - In communication with the target 这些引脚对应着这些内容。在将 LED 连接到引脚的时候,记得加上限流电阻! Pin 9,心跳指示灯:一个呼吸灯,不断的变亮和变暗。它代表着 ArduinoISP 中的程序正在正常运行。如...
if (condition) light_led1; else turn_off_led1; The "else" part is optional. "Condition" is boolean term using "true" or "false" A "true" condition lights LED1, a "false" condition turns LED1 OFF. The Arduino compiler defines "true" as the word "true", the number 1, or any ...
