Temperature and relative humidity logger

Temperature and relative humidity logger | Arduino progz | Scoop.it

This project is about building a PC-based temperature and relative humidity logger using the chipKIT Uno32 board and the DHT11 sensor. The project setup requires no additional wires (other than the USB cable) and components; the DHT11 sensor is directly plugged into four I/O pins of the Uno32 board and the project is ready to go. This could be a handy and an easiest way to setup an ambient room monitoring system for a server room. The Uno32 reads the temperature and relative humidity from the DHT11 sensor at preset interval and sends the data to PC through the USB-UART interface. A PC application is developed using the open-source Processing programming platform to log data onto an ASCII file. The PC application also displays the real-time temperature and relative humidity on computer screen.

Mug Music: Turn Water Into an Instrument with Arduino and ChucK | Arduino progz | Scoop.it

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).

Getting your Nokia 5110 LCD up and running on an Arduino | The hack shed

Getting your Nokia 5110 LCD up and running on an Arduino | The hack shed | Arduino progz | Scoop.it

We purchased one of these very cheap, very cool 84×84 LCD backlit screens off of eBay a couple of weeks ago.

It’s a very nice product for adding visual elements to your projects at a very low price. We paid £3.89 for the screen and it was delivered a few days later.

Take a look below for connection instructions and example code from Adafruit on how to get this up and running with your Arduino.

Arduboy

Arduboy | Arduino progz | Scoop.it

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.

Stupid Pet Trick

Stupid Pet Trick | Arduino progz | Scoop.it

I tried to wire the LEDs couple of times and in different ways, but it didn’t look like a emoticon smile face at all. So after unsuccessful attempts, I decided to simplify the project and turn it into a mood lamp, playing along with RBG LEDs (that I bought in Radioshack) to change colors.

During my search for a cool design for my lamp, I found this plastic ball that looks like one of those future tellers crystal balls, and I decided to used it in a mystical way. Since my idea became a mood ball, I thought it would be fun to have the mysterious ambient surrounding the future teller’s world, in this case, not future, but present.

chlonos - An open source talking multimedia clock gadget

chlonos - An open source talking multimedia clock gadget | Arduino progz | Scoop.it

Chlonos is an electronic gadget with a brain, a display, some sensors and a voice.

It's something interesting to put on your wall. It can measure temperature and light, it keeps track of the time and will tell you about it all.

The processor is based on the Arduino Uno platform, the display is a LoL Shield and the speech engine is the SpeakJet chip. Various analog sensors and audio circuits have been cobbled together. The firmware has been developed in C using the AVR gcc compiler.

All hardware schematics and source code have been released as Open Source under the GNU GPL v3 licence.

A Robotic Elevator using Lego & Arduino – Part1 | NooTriX | Arduino progz | Scoop.it

Recently, we scavenged an old Lego Mindstorms 1.5 set. It’s fully functional, but the RCX 1.5 Lego software is obsolete and does not run on recent Operating Systems. Besides, the brick has only few in/out ports: 3 inputs and 3 outputs. So, we decided to forget it and reuse Lego parts with an Arduino board.

A Digital Thermometer Hygrometer With Analog Displays

A Digital Thermometer Hygrometer With Analog Displays | Arduino progz | Scoop.it

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.

Driving Big Stepper Motors with Arduino

Driving Big Stepper Motors with Arduino | Arduino progz | Scoop.it

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.

Edible Email Notifier: reward system for reading emails

Edible Email Notifier: reward system for reading emails | Arduino progz | Scoop.it
Axel's insight:

The Edible Email Notifier (EEN) is a reward system for reading your emails. It indicates new emails by dropping M&Ms into a glass. Then, once the emails have been read, an LED lights up to indicate that you may eat the M&Ms. It was featured in Time Out New York's What You'll See at Maker Faire 2013 article, and in their print magazine. If this project continues further, the next steps would add additional functionality so the user may choose which reaction is rewarded. This way a user may unlock the M&M only after a response is sent or inbox zero is accomplished.

A polar plotter is a plotter with a rotating, extendable arm. Its characteristics differ greatly from those of a traditional plotter, which in most areas have a superior design. You could say the polar plotter is more portable or something, but mainly I made this one because it was more of a challenge.

LED Cube 8x8x8

LED Cube 8x8x8 | Arduino progz | Scoop.it

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.
