Arduino progz

Garlow is a mini GPS Watch that is based on the Arduino Nano board. It’s not really that “mini” compared to other commercial GPS watch like the Garmin, but I really made a great effort to bring the size down. In fact it looks more like a GPS clock. The first version Arduino GPS logger I built was based on the Arduino UNO, and it was larger than 2 packs of poker cards stacked together. It works just as well as a Garmin GPS watch.

in this project i want to show and explain you a range sensor with ultrasonic and a 20x04 lcd screen. I wrote the code for this project myself and added lots of comments, so that everybody can understand it and use it for other projects (maybe a light range sensor?!). It is easy to build and much more easier to program, it just requires a few cheap parts and can run on battery, for a portable rangefinder.

When I was a kid, I loved playing with Estes Rockets, so I decided to get back into the hobby but using all of my maker skizzls. So here's a really cool Arduino Rocket Launcher launching 3D Printed rockets from my MakerBot Rep2! Enjoy! Fully Open Source for anyone to make!

How to work with the NRF24L01+ module: http://www.ebay.com/sch/i.html?_trksid=p2050601.m570.l1313.TR11.TRC1.A0.H0.XNRF24L01%2B&_nkw=NRF24L01%2B&_sacat=0&_fro...

What if you could turn any conductive surface into an instrument? Like, say...a mug of water? Best of all, it's cheap; you'll only need $1 worth of extra electrical components (not including the Arduino).

This gives an overview of how to create a fully functional laser paper cutter using CDROM stepper motors and an Arduino.

The primary trick of this design is having milled cutouts made for surface mount components to be press fit into, using the circuit board as a kind of frame. Components selected have a thickness near that of the circuit board (1.6mm). Furthermore, to minimize the board thickness, the Atmega328P is inverted so that the bulk of its height below the surface. The result of equal thickness and recessed installation provides a flush appearance. The primary benefit beyond the aesthetic quality is the device is easily slid from a wallet. The high quality boards and the excellent service from oshpark also makes this build possible.

This instructable will show you how to build a portable Touch Screen Oscilloscope for less than 40 U$! The oscilloscope is one of the most powerful  ...

Use a ATTiny85 (can be ATTiny45, ATTiny44) to make an Arduino just for US3.00 and name it as Tiny Arduino.

Tiny Arduino have only eight pins as shown in figure above, Pin4 is ground (Gnd), Pin8 is 5V (Vcc), Pin1 is Reset, Pin2 and Pin3 originally used to connecting the Crystal. In order to utilize all the IO, the internal oscillator (RC Oscillator) is used to replace the external clock which require a crystal. Therefore the Tiny Arduino is now come with five IO. Below shows the Arduino IO functions.

1. There are five IO, each IO can be Input or Output
2. Among the five IO, two of the IO can perform as PWM
3. Among the five IO, three of the IO can perform as Analog Input

I2C may require to extend the features of Tiny Arduino.

It seems that you can’t visit to a microcontroller website without seeing a digital thermometer/hygrometer build of some kind. After all, it is pretty easy to build and at the same time quite useful as well. In this post, I will show you yet another thermometer/hygrometer build. But instead of using an LCD or 7 segment display for the output, I decided to go retro, using two “needles” to display the temperature and humidity readings instead.

Thoughts about MOSFET configurations for my new Arduino PWM Solar Charge Controller project. I've settled on an N-channel, high-side MOSFET configuration which is the same as the Arduino MPPT controller configuration - some nice synergy there!

Any stepper motor is great, but the big ones are amazingly impressive. There are numerous stepper drivers dedicated for use with Arduino, but they are generally limited to Nema 17 and Nema 23. Luckily, using larger steppers (Nema 34 in this instance) with Arduino is still easy. Large steppers give you an amazing combination of precision, control and torque that can be useful for anything from home automation to DIY CNC machines. In these two videos, we walk through the setup of the motor, driver, and Arduino.

Create your own 8x8x8 LED Cube 3-dimensional display!

We believe this Instructable is the most comprehensive step-by-step guide to build an 8x8x8 LED Cube ever published on the intertubes. It will teach you everything from theory of operation, how to build the cube, to the inner workings of the software. We will take you through the software step by step, both the low level drivers/routines and how to create awesome animations. The software aspect of LED cubes is often overlooked, but a LED cube is only as awesome as the software it runs.

About halfway through the Instructable, you will actually have a fully functional LED cube. The remaining steps will show you how to create the software.
