Playing around with an 8266 (have a 32 on the way) and have the deep sleep part running. I simply have a uptime sensor and an ADC as a sensor. Interestingly (not what this post is about) it updates the uptime without fail every time it comes out of sleep but not every time does it update the ADC.
It wakes for 180 seconds before going back to sleep. Is there a way I can either send a pin high 5 seconds after it wakes then say send it low 5 seconds before it sleeps. The idea being I can turn on and off the circuit its using to test thus reduce the battery usage even more. Currently the testing circuit runs all the time.
