hi do you think you could do a smaller water filter with a bottle and stones and stuff I'm doing a project and would love the help! Thanks!

This time i will try with PS/2 Keyboard Smart interface.

Hello sir, Am having one doubt in " DIY Arduino PIR motion sensor Lighting & security".

How to connect two PIR sensor in the above project??

Hi sspence! i recently read your instructable Interfacing a Digital Micrometer to a Arduino & VGA Monitor and i liked, nice work by the way !!, but i have a couple questions, i was wondering if do you need to push the button (mitutoyo cable) every time you want a data, or you can read the data in real time??? i have a digital indicator mitutoyo and i want to measure a part like circle form and take the max value of the curve (slide the part like a sweep) and save it in a variable to work with it, you think it's possible?

It's real time. You should have no problem.
Thanks for the reply, i was worried about the footswitch and the button on the top of cable but now im going to buy the cable, thanks a lot sspence!!

those buttons are used for changing a menu and taking samples, not measurements.
well, by measurement i mean take the lecture from the indicator to the arduino (samples), like a said before i wanna read all the "samples" when i make my part slide into the indicator , and for all these samples take the max (max point in arc) and save it. for that reason i was worried if i need to push the button to obtain the sample,and if i need to do that (push the button) i can´t apply this method, sorry if i don´t explain well in the begining, thanks for answer !!

You don't need to press a button. the data is streaming all the time. you can log the data or make decisions on it in real time.

I have a question, not sure if you can help me with it. I am thinking of building a solar power cellphone charger for a school project, i was wondering would it be possible to use Watt Hour meter to monitor the solar cell? So i can the charge level? Any help would be appreciated.
sspence (author)  arsh23111 months ago
as is, the project can easily monitor the solar cell. controlling the charge is a different matter. It's possible, but outside the scope of this project. That project is on my to do list.

Thank you very much for the reply. How would i physically hook the solar cell to monitor the watt per hour?

connect the watt meter in series with the + of the solar panel.

Thank you, so I can create your diy watt meter and apply it to my project?
