Things you can do with a TechDuino




Wondering what that is? I did the same when I first saw. It’s actually the local version (clone) of the most popular and fairly easy to program microcontroller – Arduino. But If you are not even sure what a microcontroller is, then let me explain.

Microcontroller is a single integrated circuit board that can be programmed to do lot of things. Basically you can make it read information from sensors and use that data to control devices or store/display data.

Here’s a few idea’s which you can do with TechDuino, let’s say you want to monitor your girlfriend’s Facebook status, so you can run to your PC, to have a chat, as soon as she’s online. You can do this by adding an ethernet shield to TechDuino, which lets you connect to internet. And write a small programme that tells the TechDuino aka microcontroller to light up bright when she’s online, dim the light when idle and to off when offline.

You can even use the TechDuino to develop commercial application, for example where garden lights can be auto switched on and off based on the brightness level by adding a photoresistor to the baseboard.

Like Imesh Liyanage mentioned in his post, the applications for this microcontroller is virtually limited only by your imagination. To know about why TechKatha came up with this not-for-profit project and it’s benefits, you can read the following: TechDuino hits stores!



Did I say it’s easy to program a microcontroller?

Yes, you will notice from the above screenshot that it’s structured programming, or in other words, human-readable high level language. And since Arduino is an open source project, you will find plenty of sample projects out there on the net, which you can download and mod it to suit your needs and load it onto the microcontroller. You can also follow the Youtube channel: “Techකතා Microcontroller Programing with Arduino” to learn Arduino programming from square one.

Basically you will be needing a computer running either Windows (XP, 7), Mac OS X or Linux for which the TechDuino USB Module Drives and the Arduino IDE can be downloaded from here and ofcourse a TechDuino™, the locally manufactured microcontroller, which is a affordable clone of the Arduino, which you can be buy at

Once you have written the programme you can load it into the ATmega chip embedded at the heart of the TeckDuino microcontroller using a USB to Serial converter. Interesting isn’t it? let us know what you are planning to build using TechDuino!




  1. Has anyone done this "example where garden lights can be auto switched on and off based on the brightness level by adding a photoresistor to the baseboard"? Where Can I get the parts?
