Hello,I would like to save power consumption when the object temperature is tested. However, I do not know how to set sleep mode for Feather M0 Bluefruit to save the power consumption. Dose any one achieve it before? Thanks in advance.Kind regards,Tang
What is your project?Do you have a wiring diagram of your project?More detail is required.
Hi Tang,It might be worth checking out the RTC (Real Time Clock) library: https://www.arduino.cc/en/Reference/RTC. It has a function called standbyMode() that puts the processor to sleep, although in the source code a comment says that it causes issues when the board is connected via the native USB port. The source code can be found here: https://github.com/arduino-libraries/RTCZero.There's also an example SleepRTCAlarm: https://www.arduino.cc/en/Tutorial/SleepRTCAlarm.
