Blinky on Arduino Zero

Run a powerful open source Operating System on Arduino Zero to blink an LED on the board and open up a whole world of control capabilities! Story Version: Version: 0.9.0 (latest) We decided to write an open-source, hardware-agnostic OS for commercial IoT devices that provided low level configuration options to deal with power, memory, and performance constraints across various types of micro-controllers and ...

Control an Arduino Zero using Node.js

I had to delve deep into the code, but I finally got nodebots working on an Arduino Zero Story I recently received an Arduino Zero, arduino.cc’s latest offering. I’d been experimenting with nodebots, so I decided my first Arduino Zero project would be a nodebot. Anna Gerber has an excellent tutorial for doing nodebots using Arduino at http://node-ardx.org/ Not only is it well written and suitable for beginn ...

A Simple Arduino LED Example in Proteus

Hello friends, I hope all are fine and having fun with your projects. Today, I am going to share a very Simple Arduino LED Example in Proteus ISIS. I have designed a very basic example in Proteus in which I am going to blink single LED first using Arduino and then I am going to blink multiple LEDs in Proteus. When you start working on Arduino then Arduino LED example is the first example which you must try ...

L293D Motor Controller Tutorial

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 with other breakout board to combine with the motor controller (of course you can buy a L298N motor cont ...

A Tutorial For Launching Your First Balloon

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 its a great way to get amateur radio into the classroom and g ...

Arduino UNO Tutorial 6 – Rotary Encoder

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 per complete turn varies. The Sparkfun Rotary Encoder has 12 steps but others may have more or less. The diagram ...

Tutorial 19: Arduino Dice

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 pins. Prerequisites Know how to use a DIP IC, e.g. from tutorial 17 – Electronic Dice. Read about seven ...

Tutorial – Using DS1307 and DS3231 Real-time Clock Modules with Arduino

We keep getting requests on how to use DS1307 and DS3231 real-time clock modules with Arduino from various sources – so this is the first of a two part tutorial on how to use them. For this Arduino tutorial we have  two real-time clock modules to use, one based on the Maxim DS1307: and another based on the DS3231: There are two main differences between the ICs on the real-time clock modules, which is the ac ...

Nokia 5110 graphics tutorial

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 one pin which is controlling whether backlight is on or off. It will be on if the pin is connected through ground and ...

Arduino Button Tutorial

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 configuring pins, using pull-up/pull-down resistor, deglitching, detecting states versus ...
