# How can I measure the current, in a precise way, using an arduino? [closed]

I designed a low noise current source for a project in my university and I would like to know if it is possible to measure the provided current using an arduino and a LCD.

• Use something like an ACS712 in addition. Jan 24, 2018 at 9:46
• I would like to know if it is possible ... . Yes, it's possible. Jan 24, 2018 at 9:48
• @H.Puc thanks, I didn't think about sth like that. Won't it add some noise at the output of my current source? Jan 24, 2018 at 9:54
• There are many ways to do this. However, ready-made devices are available for this purpose. Why not just use one of those like a current meter. What is your advantage of making a current meter yourself if not for education purposes that is. Jan 24, 2018 at 9:55
• @JavierGarcia if you are going to ask questions about noise you need to give more technical details of the current source and its noise levels. Jan 24, 2018 at 9:56
