I want to measure the total current consumption in my car, I want to add additional electrical items and worried I will have a flat battery. I also want to log the current, so thinking ardunio would be ideal to show the data with rtc to provide time stamp.
The question is how to measure the...
I am working on a mini project for a school who want to detect sound levels in the classroom and been going around in circles for a few weeks. They want to measure sound levels but ranging from very low sound i.e. chair moving, door opening to levels of talking within the classroom.
I...
I want to build a box which monitors certain levels in our office, I am having problems with getting the sound level monitoring. I have purchase a couple of Arduino microphone boards. but the sounds level voltage is quite low and looking at an LM386 amplifier. I have done a lot of searching on...
Thanks for the quick response, the 7805 will regulate the battery voltage down to 5v.
I have to think if it's possible to isolate the battery charger from the current load, to allow the battery to be charged which the data logger is running.
I have a small electronics data logger board which I want to run remotely and plan to use a RC car Lipo battery pack. There are loads of small package batteries and the ideal for by project.
I can buy a charger, but there might be a need to run the electronics and the batteries while on...
