DIY Amp / Watt Hour Volt Meter – Arduino

Major corrections and additions made 9/9/2014 For my off-grid Ham Radio and Solar projects, I needed a way to measure volts, amps, watts, amp hours and watt hours. There's a couple of commercial products that can do this, but not with the flexibility I wanted. I designed a Arduino micro-controller based solution that is very extensible. Right now it monitors the above values of attached gear, and I'm thinki ...

Control Arduino Wirelessly with MATLAB

Been seeing few DIYs on how to establish a communication between MATLAB application and Arduino that is hardwired to PC. However, I haven't encountered anything that control Arduino via MATLAB wirelessly using the ENC28J60 compatible Ethernet shield. In this ible', I'm going to show the simplest way to control Arduino using MATLAB wirelessly. WHAT YOU NEED? 1) Arduino - You need a controller. I used Arduino ...

Electronic Instrument

This electronic instrument allows you to sequence and loop audio and MIDI data.  Most of the time I use it to sequence drum samples so I can play around with different beats and rhythms.  The really great thing about this instrument is that it is very portable, it fits in your hands easily, runs off a single 9 volt battery, and has a headphone jack that you can plug into.  If you connect it to your computer ...

Arduino hardware hacking: Part 3

In our previous two tutorials (see here and here), we created a Simon-type game using the Arduino, a hardware platform for simple, and not so simple, electronics projects. We placed three buttons and three LEDs on to something called a breadboard, and wrote a small program that would send a random sequence to the LEDs, which the player would then need to replicate by pressing the buttons in the same order. ...

Arduino hardware hacking: Part 2

In part 1 of our Arduino tutorial seres we covered the basics of how the Arduino works, and we're going to use that knowledge in a hands-on project and see how this open-source hardware programming environment works when we're actually trying to get something done with it. After this, you'll have more than enough information to be able to tackle your own projects with confidence - we're going to build on th ...

Arduino hardware hacking: Part 1

Arduino is cool. It's cool because it's a tiny device - about three inches by two inches - that comes with a USB port and a programmable chip. It's cool because you can program it using a very simple programming language known as Wiring. But most of all, it's cool because the entire reference design for the hardware is available under a Creative Commons licence, so you're free to build your own if you want ...

RC Rocket Launch System

This instructable will show you how to make an RC launch system for your Estes rocket, which can be operated with a TV remote. What it does is it allows you to press the center button on your TV remote, and it'll automatically launch your rocket. In this way it is basically a wireless version of the standard launch controller. But this is not all it does. You can use the up and down arrows on your remote to ...

Botanicalls Clone using an Arduino

During the past spring a good friend of mine bought me my first house plant, a Lady Palm, and I’ve found myself rather invested in keeping it alive. To that end I wanted to monitor the plant’s environment so I could ensure that its needs were being met. My first thought was another ITP project, Botanicalls, which is an open-source, Arduino-based networked soil moisture meter. In its original application, th ...
