Arduino Basics

Introduction Nextion is a programmable human machine interface (HMI) that can be customized and designed to simplify the interaction between you and your project. This Nextion Enhanced module (NX4827K043) with a resistive touch screen display, has some additional features not seen in previous traditional versions of the Nextion series. A built in real time clock (RTC) Accessible flash memory (32MB) GPIO functionality Faster clock speed Before you connect the Nextion Enhanced module to your project, you need to design your interface with the free Nextion Editor. The editor can be downloaded here. In this project, I will be designing a simple dynamic interface, which will allow me to interact with a stepper motor in two different ways. The first interface will let me control the direction and speed of the stepper motor through the use of a simple GUI. I will have left and right arrows for the direction, and up and down arrows for the speed. I will also map the Expansion board...

  Description This is a fun project that will surely impress anyone you make this for. If you are having a "Disco" themed party, you cannot have a boring old cake. Let me tell you, this is probably the only Arduino project that my wife has ever been willing to be a part of. She did the hard work of putting the cake together, and I, well.... I was in charge of lighting. My biggest fear was that one of the wires would come loose and ruin the event at the most critical moment... While a wire did come loose, I managed to fix it in time before the guests arrived. Ok enough of my monologue, let me show you how to make one of these things.   Parts Required: Arduino UNO (or compatible board) 4 x WS2812-B Programmable Colorful LED Board 330 ohm resistor 4700 uF 16V Electrolytic Capacitor Breadboar...

Description Have you ever wanted to transmit Arduino data over the internet? In this tutorial, we will design a web page that will retrieve Analog readings from the Arduino's Analog Pins and display them on a bar chart within the web page. The web page will use jQuery and AJAX to request the data from the Arduino Web Server, allowing us to update the bar chart dynamically, without having to refresh the entire web page. The Arduino Web Server will send the Analog readings to the web page in JSON format where it will be processed and displayed accordingly. In this tutorial, I will not have anything connected to the Arduino's Analog pins, which means the data retrieved will be that of randomly floating analog pins. Feel free to connect a potentiometer, temperature sensor or any other analog sensor to these pins if you want to create a more "useful" project....
