Basically the fun with playing gadgets such as Arduino, Gadgeteer and others comes from sensors. Because they are how your system interacts with the real world. And writing code that acts upon some readings from the real world is fascinating!

So let’s get started with using the motion sensor. I have a very generic sensor from Parallax and fortunate enough to find an article that explains exactly what I needed: Using motion sensor with Arduino. Check out the resources section down below to access the original article. Unlike the LCD, it’s quite simple to connect the motion sensor to Arduino. The sample code lights the onboard LED when the motion sensor detects a motion. Check out the video for a short demo. When the sensor “senses” motion, it goes red and the LED starts blinking.

I think the next step would be to connect both LCD and motion sensor to display the alarms on the display. Hope I can make that project happen without too much delay.

I’ve been looking for a good tutorial to connect the LCD screen to Arduino. There are a lot of tutorials everywhere but Interestingly most of them just show the final version with all the cables jumbled up. After a lot of looking around I finally found a simple, step-by-step tutorial with clear illustrations: http://www.codingcolor.com/microcontrollers/connecting-a-lcd-to-arduino/

This is a great tutorial and I recommend it to anyone who wants how to connect LCD to an Arduino.

The most popular development boards is without a doubt Arduino. It is open-source and it’s been around since 2005. There are lots of different models and libraries. My goal for now is just get started and see it in action. To achieve this, first stop is the official site where you can download the drivers and IDE. After download simply unzip the contents to a folder.

A great place to start playing with it is Adafruit. You can find the link for Arduino tutorials in the resources section below. I simply started with Lesson 1 and changed the speed of the onboard LED.


So it takes minutes to get started with it and comes loaded with a bunch of examples so they made it very easy for beginners.


Error: stk500_getsync() not in sync resp=0x00 This error means that Arduino couldn’t be found in the COM port. To resolve the issue:

  • Use Device Manager and make sure Arduino is connected. It should be listed under Ports node. Note the COM port number
  • Then from Tools –> Serial Port make sure the correct port is selected.
