More components

My wife surprised me recently with a few new additions to my electronics set. There have been a few components I was in the market to get and experiment with. These were the Ethernet shield, Wiichuck adapter and mechanical relay.

Ethernet Shield

.

The DFRduino Ethernet Board V2 (From http://www.DFRobot.com)

The shield I have is manufactured by DFRobotics called the “DFRduino Ethernet Shield V2” as an Ardunio Ethernet Shield clone. It has network capabilities and supports SD Card read/write. All official Arduino libraries work on this board.

Adding network capabilities to your existing Arduino comes at the expense of 4 digital pins (namely 10,11,12 and possibly 13) but is a small sacrifice if you can connect to the internet. This board also supports network connections up to 100Mb/s.

The shield stacks atop my Arduino Uno and feels like solid workmanship. The shield is compatible with the Uno, Dumlinove and Mega boards. Read more…

Arduino: Testing a Thermistor

Winter is upon us! And I thought to myself, its cold, but I do not know exactly just how cold it is. So I went online and found a

Tools for Thermistor test

Tools used for Thermistor Sketch

sketch (on the Arduino website) which experiments with a thermistor.

A thermistor  is a electronic component that registers a change in resistance in relation to the change in temperature. So the sketch requires:

.

  1. Arduino
  2. 10k resistor
  3. 10k Thermistor
  4. breadboard
  5. Jumper connectors. Read more…

Serial Communication: Turn On and Off Arduino LED

Wrote a script for the Arduino to listen for a byte of data and depending on that value turn the LED on the Arduino Board On and Off. Read more…

Send serial data (strings) from Arduino

March 12, 2011 Leave a comment

So I have some spare time, so I looked at the Serial Communication using the Arduino device. I was able to successfully send messages from the Arduino board to the Arduino Serial Monitor on my laptop. I was able to send simple  hard coded values as well as dynamically generated string messages.

Arduino Uno unpacked

I finally got my hands on a Arduino Uno. I was surprised at how small the unit was, as it’s slightly larger than a box of matches. After downloading the latest version to date of the Arduino Integrated Development Environment (v0.22), I managed to install the drivers on windows 7. Read more…
