After searching for a while I finally found an Arduino Bluetooth 4.0 shield from RedBear. My main aim was to able to control an Arduino from iPhone using Bluetooth 4.0. Today I used SainSmart 8 Channel DC 5V Relay to play … Continue reading
For the past two days I have literally lost my patience with Qik 2s9v1 dual serial motor controller. I have referred so many website and I could not make this controller work. After hours of searching I found this library … Continue reading
Today was a busy shopping day in Deira, Dubai. Finally found a location where I can buy electronic stuffs like resistors, capacitors, LED etc. The things I bought today was Regulated Power Supply Soldering Station Once I was home, I … Continue reading
The learning process with Arduino continues… Last week I had ordered bunch of goodies from Sparkfun, and today morning I received them. I tried to assemble few circuits, but I understood I need to get a decent soldering station to … Continue reading
This is a mini project using Arduino. This uses a temperature sensor and Arduino Uno.
