Dear Arduino experts,
As an absolute beginner with little to no experience, I am currently working on a project that I would like to incorporate an Arduino as a counter.
My project is to try to use Arduino to take pulse signal (ranging from a specified voltage to eliminate lower level noise all the way up to 5 V) from a detector with a counting rate to be expected around 300 counts per minute, convert this pulse signal into counts per minute (with timestamp) then store the information on an SD card. The platform I am using now is Arduino Uno R3. I have yet to find good information on what I am trying to achieve so I have no idea how should I do this thing. It involves a lot of functions so I will try to organize them a little bit.
- Employ a effective and sufficient ADC to convert the signal;
- Set up an adjustable lower level discriminator to throw out noise;
- Bundle up the information into counts per minute with timestamp;
- Write the information above into a SD card.
Few extra questions I have after some reading.
- Do I need to use a faster ADC other than the built-in one judging from my count rate?
- Since I do not care about the amplitude of the pulses as long as they are over a certain threshold, maybe there is an easier way to do what I want? Some sort of gate thing?
Feel free to throw in anything related that you think would be helpful (equipment, things to read, etc.), I am trying to learn the stuff.
Thanks in advance.
