Hello, I'm trying to make a current limiter which i can adjust from 10 mA up to 3A. I found this document:
http://fritzing.org/media/fritzing-...r_files/external current limiting circuit.pdf
The last circuit on that page (Current Limiting up to 8.4A) works fine except that i can't make the current go lower than around 300 mA, i can adjust R1 to change the max current but i don't know how to make it go lower. Tips? Thanks!
