L293D is a chip that enable us to control two motors together with only one Arduino board or other microcontrollers. However, I was having a project that required controlling four DC motors together. Recently i brought a L293D Arduino Shields , it covered all of my pins that i need to use them to connect […]
Why Launch A Weather Balloon? There are a lot of reasons to put together a weather balloon launch. Its a great project for a STEM /STEAM class, it requires planning, electronics and programming, and teamwork. It has a lot of great classroom applications, giving a tangible demo of aerodynamics, physics, meteorology, geology, and more. Additionally

We have written a tutorial for Rotary Encoders using a Microchip microcontroller but now would be a good time to make an Arduino UNO version. With a rotary encoder we have two square wave outputs (A and B) which are 90 degrees out of phase with each other. The number of pulses or steps generated
In this tutorial you will build a dice that is shaken by holding the button in and thrown by releasing the button. The shake, throw and number thrown are animated and displayed on a seven segment display. A 74HC595 IC is used to interface the 7-segment display to the Arduino, using only 3 Arduino digital

Use the Maxim MAX7219 LED display driver with Arduino in Chapter 56 of our Arduino Tutorials. The first chapter is here, the complete series is detailed here. Update – 4/1/15 – This article is pending a re-write, please refrain from comments and questions until the new version is published. Introduction Sooner or later Arduino enthusiasts and beginners alike will come

Step 1: Connections First let’s connect the Nokia 5110 display. Remember that the LCD runs on 3.3V and although some people have connected it to 5V, it has worked but gave some weird effects, so I suggest connecting to the 3.3V output of the arduino. Next, the LIGHT pin on the LCD. It is the
What’s simpler and dumber than a button, you ask… I say: behind a button, unexpected things can hide. And within a program that does various things, handling a button can be tricky. The nice thing is that interesting functions can be built with a simple dumb button. This tutorial will address these aspects: wiring and
This is something that almost every maker that is interested in easy electronics should know how to do. It is great for decorating or just experimenting for starters. I am doing this tutorial because I had bought an RGB display from the Maker Shed and it was hard to track down the instructions. First I

The Arduino Cellular Shield allows you to make cellular telephone calls, and send text messages. The brains of this shield is the SM5100B which is a robust cellular module capable of performing many of the tasks of most standard cell phones. This shield requires use of a SIM card to connect to a cellular network.
