My Motivation This winter my girlfriend had a lot of trouble waking up in the morning and seemed to be suffering from SAD (Seasonal Affective Disorder). I even notice how much harder it is to wake up in the winter since the sun hasn’t come up yet. Symptoms of severe SAD can include irritability, oversleeping […]

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 […]

Close Encounters of the Curiously Minty Kind. This Instructable will show you how to build an Altoids version of the ‘Close Encounters’ mothership, and how to interact with it. This may be vital training for that day when the Bright White Beam comes to suck you up into the unknown. It will also introduce you […]

Environmental energy harvesting is a possible source of power for Internet of Things (IoT) sensor nodes but needs careful management. Unless harvesters based on solar or thermal technology, for example, are designed to be compatible with conventional circuits, DC/DC converters need to be optimized for low-voltage inputs. Sensor nodes for the Internet of Things often […]

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. […]

Micrel’s family of low-profile step-down power modules integrates a synchronous buck regulator with an inductor into a 2.5×3×1.1-mm QFN package for the 1-A MIC33163/33164 and a 2.5×3×1.9-mm QFN package for the 2-A MIC33263/33264. The modules offer 100% duty cycle operation and accommodate an input voltage range of 2.7 V to 5.5 V. Incorporating Micrel’s FleaFET […]

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 […]
