Running off of 1900mAHr AA batteries it should sleep, still doing 10Hz sampling to detect motion, for 6-7 years. With the 9V batteries in my prototype at 590mAHr it is just shy of two years.

AVRs and other microcontroller architectures have sleep modes for at least 10 years. the guys who made Arduino just decided to do a full-speed main loop; I guess they thought it was easier for non ...

The sleep routine is a separate function, called from the main loop. As usual with Arduino, the ‘pin numbers’ aren’t the actual chip pin numbers, unless by coincidence. The led pin was correct for me, ...

Arduino sleep-tracker DIY. John Biggs. 10:31 AM PDT · August 1, 2008. Anita Lillie at the MIT Media Lab created an Arduino-based sleep tracker to process where she keeps her arms while thrashing ...

The sleep monitor was developed using an Arduino Nano for their final ECE 4760 project and takes the form of a base station and glove which measures heart rate using an infrared sensor together ...

Going to sleep for my ATtiny involves calling Big Dan’s sleep function, which needs to be included in the programme. I used xnich1’s ‘buttonActive’ boolean flag as an indicator that the push-button ...
