Ok, I have not been diligent in producing some software. Most of the algorithms that I have seen to do this job are rather slow. I have defined a MAX_LETTERS as a constant of 10 which will give me generous room for my ID Code. Since I like to modular my code I will need to write a function void sendTone( char 'letter' ); BTW this device (Arduino) is a listener con the CAN bus.   MorseCode.h MorseCode.c // morseCode d==dot D==Dash //morseCode[value][string]   char morseCode[26][MAX_ ...

Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   Hi, these are terrible days, in Italy we have been locked in the house for days to avoid the spread of Coronavirus. What's better than designing and building something with Arduino? I thought of creating a small circuit that, based on the values of temperature, humidity and brightness, can set 8 so ...
I did this project back in 2012 as my minor project. This project was inspired by the need for a method to neutralize threats without the direct intervention of humans. That was the time, my country was hard hit by violence which motivated me to develop and simple robot vehicle that can be operated by any mobile phone. The robot is controlled via DTMF audio frequencies which enables it to have wider operational coverage even in 2G networks.   Let's inspect the basic structure of the robot. ...
...Three Projects have been submitted for this month's Project14: Acoustics ..hope you would like it!   BUILD(I): The Annoying 'CAPS' Lock Buzzer   The CAPS LOCK key is the most annoying key on the keyboard. Majority of the times, you have noticed, It’s always getting in the way. Ever enter a password with CAPS LOCK enabled? Huh...   Enough times to get locked out of your account?  Yeah, me too..(only sometimes).. I Agree' Even Google decided to drop it all togeth ...

I was tempted not to post this project because it didn't turn out how I wanted.  So what changed my mind?  I was reading some older posts and one of the community veterans had commented that projects don't always turn out right. Yup.  So I'll share what I learned along the way and maybe someone else will build the better mouse trap - or dog yap trap and I can sleep past 6am on a Saturday.   Like many a tinkerer, the 555 has a special place in my heart.  It's one of thos ...
Introduction  I have wanted to build an ultrasonic object detector ever since I saw a post on one. I have seen several projects on ultrasonic object detectors. However, all of the projects tethered the sensor to a PC. I wanted a more portable solution. So I designed an ultrasonic object detector that the user could place anywhere that had Wi-Fi connectivity. The ultrasonic object detector sends the sonar data to the PC via Wi-Fi. The PC then displays the data using a simulated sonar screen ...

Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   The 1DUltraBot is now finished, apart from the final 3D printed flat top piece. The circuit diagram is illustrated below and is very simple. One digital output (D2) from the Nano to control the servo motor and two (D6 and D7) to control the ultrasonic rangefinder module. The servo motor is connected ...

Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   After moving and lighting stuff for months, I moved to some, hopefully nice, acoustic/audio project. In this context, the project I am presenting, as well as the next projects I have in mind, are more acoustic projects than pure audio builds. This project has been published for the first time on ...

Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   I have been pottering on with the 1DUltraBot for the Acoustics Project14 activity and now having a working chassis. I decided that rather than try to make my own chassis to follow the 5 foot ruler that I would adapt an existing child's small toy car. I was originally just going to use the axles and ...
