Hi,
I am looking to create a standalone circuit (battery powered) that can record the time (and date if possible) when a button was pushed. Assuming a button push outputs a 5V DC signal. Then would need to be able to retrieve this data from the circuit.
Any ideas where I could start or are there any existing solutions? A nice AC powered USB DAQ would be nice to use but too expensive and requires AC - but maybe there are some devices you know of that would be similar?
Thanks a mill,
