  • So I’m looking at potentially using this to monitor vibration on something being machined but I’m concerned about the output. The max frequency I expect to see on my part is 1500 Hz and the ADXL can go up to 3200 Hz so I’m covered on Nyquist Rate there but I’m concerned about the Arduino. Given that the processor is 16 MHz and it takes a good number of instructions to poll all the registers and write them to an SD-Card or something, I’m thinking the controller won’t be fast any.

    Without going through the math of operations/cycle, does anyone think this is a reasonable frequency to use this application at?

No public wish lists :(
