The reason to make these relatively complex time-lapse systems is to control three things – the camera shutter, the grow lights for the plants, and the photo light for the exposure. To grow plants over long periods of time requires a grow light that stays on for 12 to 18 hours...
I can get the first part to work (wakeup from deep sleep) if I mark the boot counter was RTC_DATA_ATTR but that won't survive a reset. So according to the docs (https://docs.espressif.com/projects/esp ... types.html) there is an __NOINIT_ATTR option and there's also the RTC...
measure pulse from 2-3us to 3 minutes but the first one uses an assembler routine to make the measurement while the second one uses the Timer0 interrupt to calculate the result.The first one: pulseIn, can be used if interrupts are turned off (and if they are off will return a more ...
Hi, I'm developing some code where I want to track the number of times the system was booted, both when woken up from deep sleep as well as when the user presses the reset button. I can get the first part to work (wakeup from deep sleep) if I mark the boot counter was RTC_DATA...
How to Program a Schmitt Trigger on the Arduino The sketch below reads the signal from the Schmitt trigger and increases a counter by one digit with every press of the button. The count is printed to the serial monitor. Once the Schmitt trigger is connected, upload this code to the Arduino...
Keypads can be added to a myriad of Arduino projects, for learning, or for real world projects. In addition to controlling access to things, these keypads can also be used as simple input devices to control other things. Bob at I Like To Make Stuff even used his Arduino Keypads to ...
