Introduction An excerpt from OmniGlot.com about the origin of Morse Code: Morse Code was invented by Samuel F. B. Morse (1791-1872), a painter and founder of the National Academy of Design. He conceived the basic idea of an electromagnetic telegraph in 1832, and produced the first working telegraph set in 1836. This made transmission possible […]

I have created this wiring diagram for the connections between the motor controller, motors, and sensor shield. I’ll update it later to include other components. And here is an update that includes the servo motor and the range sensor. And here are the detailed pin assignments for all modules: PIN ASSIGNMENT Arduino Pin Description Motor […]

All about power today.. For a while now, I’ve been looking around for a mains (220-240VAC) power monitoring circuit that I might be able to interface with an Arduino.  There is of course the OpenEnergyMonitor solution, but they seem to use a transformer to isolate and measure the mains voltage.  The transformer doesn’t exactly couple to the […]

Introduction This tutorial will walk you through downloading, installing, and testing the Arduino software (also known as the Arduino IDE – short for Integrated Development Environment). Before you jump to the page for your operating system, make sure you’ve got all the right equipment. What you will need: A computer (Windows, Mac, or Linux) An […]

There are a lot of LED cubes on Instructables, so why do another? Most are for small cubes consisting of 27 or 64 LEDs, rarely larger since they are limited to the number of outputs available on the microcontroller. This cube will be 512 LEDs, and will only need 11 output wires from the Arduino. […]

Introduction This project explores a couple of ways of simulating and using a bar graph with the Arduino. Bar graph components like the following one can be used, This type of bar graph is basically just 10 LEDs in a row with anodes on one side of the component and cathodes on the other. The […]

Here’s a fun system designed to take care of some of the headaches involved in breadboarding a circuit. It is is a simple set of template files drawn to scale with real world electronic components. Using a vector drawing program you simply move the components onto the breadboard template, draw a few wires and print […]

Over ten years ago, I put up a web page with detailed instructions on building a simple electric motor based on one from the Beakman’s World TV show. I called it the “Beakman’s Electric Motor” page and over the years it has had hundreds of thousands, if not millions, of hits. Realizing that just building a motor, […]

UPDATE 22-12-2014 Instructables user mattpbooth has updated the code and is hosting it on github: https://github.com/mattpbooth/ArduinoNESController… Thanks Matt! UPDATE 03-12-2011 Replaced a println with print (derp). UPDATE 01-12-2011 Remade all code from scratch. Remade ‘ible code section; Now includes a ‘Processing COM port config for dummies’ Ladies and gentlemen, I proudly present 8bit pleasure.. yours […]

In this project, we will demonstrate how to build temperature sensor circuit using a LM35 sensor. As a temperature sensor, the circuit will read the temperature of the surrounding environment and relay thi temperature to us back in degrees celsius. The IC we will use to measure the temperature is the LM35 IC. We will […]
