Any multimeter would be good enough, but surelly not obligatory to have one.Would be more interesting to own a oscilloscope, but I'm not sure how much they cost in the US, they are quite expensive in BR.But yeah, if you want to move forward it would be nice to start with any dirt cheap multimeter. For example: if you want to measure current in a circuit which has an LED and a battery, you connect the negatives of the battery and LED, then multimeter's negative probe to LED's positive pin and multimeter's positive probe to positive of battery. A multimeter is really a basic diagnostic tool employed by those utilized in the electronic or electrical industry. Input impedance is particularly important when it comes to sensitive control circuits and electronics, and a DMM containing good input impedance will have very little influence on the performance of the sensitive circuits. One of the best things about being a maker is the ability to make your own tools. This section helps with covering basics, but you might be thinking about determining much more about breadboards, electricity, circuits, etc. I've read that some USB scopes are pretty much toys, but the Pico Technology units are of professional quality.
