An Arduino LED Control Tutorial

arduino rgb led tutorial

The “hello world” of microcontroller programming is blinking a LED. As an introduction to Arduino programming, we’ll code several simple Arduino LED sketches; we’ll be blinking a LED, make a LED respond to an input and fade a LED. I’ll also show you how to easily manipulate multiple LEDs and …

Connecting a Servo Motor to An Arduino

Arduino Servo MG996R

Building robots with Arduino starts with knowing how to move objects through motors. There are a lot of type of motors used in microcontroller-based systems: dc motors, stepper motors and servo motors.  In this Arduino servo motor article, I will discuss what is a servo motor and how to use …

How to Manipulate Arduino Pins Simultaneously

Arduino Pins Map

If you've code PICs before Arduinos one of the things you might have notice is the lack of function on the latter to manipulate multiple pins at once. Manipulating all the Arduino pins at once is needed, for example, when using a seven segment display or creating strobe lights. Is …

Arduino Library: How to Create Your Own

arduino library

One of the strengths of the Arduino platform is the extensive library included in its IDE. Libraries make life simplier for coders; imagine how hard it would be if there's no LiquidCrystal or Servo library ready for use. In my experience, projects were done in shorter time because of the …

How to Use Arduino as USB to Serial Converter

arduino usb serial converter

If you want to do serial debugging for your PIC, ESP8266, Bluetooth module and a TTL-to-USB converter (pictured below) is nowhere in sight, you can simply use an Arduino USB serial converter!   The Arduino UNO has its own FTDI chip whose function is to convert TTL signal levels to USB. …
