HDC1000 temperature and humidity sensor breakout, with Arduino library!

Some time ago I came across a new chip from TI, the HDC1000. It’s a temperature and humidity sensor with I2C interface and requires little to no additional components. It comes in an 8BGA package: we can all agree it’s pretty small. Some of the peculiar characteristics of this chip are that it has a DRDYn pin which goes low any time there is a new reading from the chip (so you can precisely time your reques ...

How to Display Text on an HD44780 LCD with an Arduino

In this article, we will go over how to connect an HD44780 LCD to an arduino in order to display any text that we want to show on the LCD. To do this, first, we must make the appropriate physical connections from the arduino board to the LCD. Then after, we must write the code so that whatever text we want displayed comes up on the LCD. LCDs are pretty much the standard now in order to display text to users ...

DIY Antique Phone Doorbell using Arduino

Bryan Zimmer emailed us this fantastic retro-themed DIY hack, a most timely submission as we just revisited the noir art deco-science fiction classic Dark City and we think this would have perfectly fit in the world (or in Adama's quarters on BSG). Bryan gives step-by-step instructions of how he converted a 1940's Swedish-made Ericsson bakelite original into a wireless doorbell... This project combines a ba ...

Controlling speed controllers with Arduino

Hey guys, I'm back with another instructable. This is about RC speed controllers. What this will do is allow you to test out your speed controller in the Arduino world using Serial, then you write the values down and can use them for your projects. Submitted by Newton Labs for the Instructables Sponsorship Program Step 1: Setup All you need to do is hook up your speed controller to your Arduino, red(s)-> ...

Arduino Touch Screen iTunes control (ATSIC) using arduino

What I'm going to show you is how to make an iTunes control device using an Arduino and a touch screen. The iTunes Control works by reading area's of the touch screen and send a letter to the computer via the serial port, which is monitored by an apple script which run a command based on the info it receive. This is my first Arduino project, until I made this project I had never used one before, I found the ...

DMX Ardweeny Node using Arduino

I've settled on the lighting industry standard of DMX as my overall control protocol as I explore the world of blinky lights.  This universal control method is electrically robust, radio transmissible, and flexible enough for my needs (not to mention the needs of major concert, theatrical, and entertainment venues.)  There are a variety of DMX sequence controllers from free to thousands of dollars. To that ...

Control a Relay with Arduino

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan. When the button is pressed the fan will turn ON and will remain in this state until the button is pressed again. Arduino Control Relay Schematic How does the circuit works When the button is pressed the Ardui ...
