DIY Miniature Multimeter
element14 Presents | MAYER MAKES VCP Profile | Project Videos
Breadboarding is often the start of great projects but measuring on Breadboards is often not so great. The standard multimeter leads don't fit into breadboard holes and alligator clips are needed to connect to the circuit. There must be a better way! Clem designs a tiny Multimeter dedicated to be used with a breadboard! Easy to connect, battery powered and it even has a WI-FI so you can view the readings on your phone!
