Hello,
I am looking to record or store certain events with time using an Arduino system. To be precise, can you help me develop a simple system that will have an IMU and a clock with storage where I can save events with time when it gets triggered, i.e. save the timing of a trip/fall/balance loss when the IMU detects deviation.
Thanks
What does IMU measure and what is it? To me it means an International Measurementsm it could be Inertial Measurement Unit! Regardless you monitor its output, and when you get that you can create a timestamp and save it in memory. There is internal EEPROM memory in the arduino but you can also add a SD card reader/writer module and of course a RTC (Real Time Clock) module. If you want it self contained you can add a LCD display, Bluetooth, Wi-Fi module etc. Here are some choices for IMU!

Good Luck & Have Fun!

Use a Real Time Clock (RTC) module.
Think about adding an SD card to store the data.
Look at buying a "datalogger shield" which has both of these components. You may even find one with the IMU chip on it too.
To make a time stamp with the Arduino, simply store the current value of milliseconds as follows:
unsigned long event_time_stamp = millis();
This will save the number of milliseconds since program startup. The built in clock is not very accurate and will gain or lose several minutes every day.
If you need an accurate time stamp, or date information, you will need an external RTC (Real Time Clock) or some other source of time information.
