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.
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…
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
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:
- 10k resistor
- 10k Thermistor
- Jumper connectors. Read more…
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…
Took 30 mins out of my day to quickly code an app to send and receive serial data to my Arduino Uno. The app is simple in terms of just setting the Baud rate and the port name required to open a connection to the Port. Read more…
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.
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…
