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 […]

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

What is a tilt sensor? Tilt sensors allow you to detect orientation or inclination. They are small, inexpensive, low-power and easy-to-use. If used properly, they will not wear out. Their simplicity makes them popular for toys, gadgets and appliances. Sometimes they are referred to as “mercury switches”, “tilt switches” or “rolling ball sensors” for obvious

If you ever wanted to integrate RFID functionality into your project, this small tutorial might help you accomplish that. I used the RDM630 module from seeedstudio in its UART version. It comes on a small board with presoldered connectors which fits perfectly on a breadboard. You only need to connect the antenna to the two pin socket.

Seeing so many persistence of vision ideas on the web was too tempting not to try one. After considering several different motors to drive a display, a ceiling fan seemed to run at just the right speed, is out of the way, and very quiet compared with alternatives. With a micro controller based on the
