I have a question related to applications.
I have an (several in fact) Arduino Uno and have played with it (them) since years.
I enjoy doing this. I started with the « blink » application.
I have learned many things, including low level programming with registers.
I worked mainly on two projects :
A clock displaying the time, day and year + temperature + humidity on a 16 x 2 LCD screen. The hardware is inside a « vintage » box.
Well it was fun. I have bought recently a TFT 3.2 inch screen which is much bigger than the LCD display.
I have played a lot with the timers (low level, using the Atmega 328p datasheet) and a 12 bit Digital to Analog Converter (DAC) for musical apps. I have tabulated sinusoids (on the equally-tempered scale) and played midi-like pieces through the DAC and an amplifier.
I have also used a micro SD card. Using the Serial Peripheral Interface, the program read the audio file (wav) on the card and play it using the DAC at a given sampling frequency (timer interrupt). It was also fun, and difficult though.
Now it happens that I do not have any new project!
The thing is that I am interested in the technical part and I find the Arduino really « genial ». I have spent a lot of time learning technical stuff, really. But if I don’t have any goal, it becomes pointless.
I have this feeling that the mainstream fields are educational applications, robot related applications and home automation ones.
I am not interested to these applications!
I don’t say that they are not interesting.
I am not aim criticizing all the projects that are proposed on the web.
Trust me I have googled « arduino application fun ». I have been in several FabLabs. But still haven’t found what I’m looking for…
Could anyone help me?
