I'm just getting started with electronics (arduinos and friends) and I would like to get a multimeter. As far as I can tell arduinos and any other logic chips and circuits I'm gonna be using are using DC power in the 3-12V range. Multimeters with "true RMS" seem to be quite more expensive than those without and well... do I need this feature at all? Is there any other feature I should look for?

  • Will you be working with AC or only stay in the 3.3-12V world?

  • No, you don't need true RMS for getting started (but pay more than 15€). And it's worth reading what peak-values, mean and RMS is and why the readings might differ if the signal isn't a sinus

  • Also consider buying a logic analyzer (5 euro from China), these work in the range of about 0-5V (maybe more).

For experimenting with microcontrollers, you don't need a multimeter with true RMS. Get a cheap V, mA, and Ω meter, and save the money for a scope. You will soon be lost without at least some way of looking at voltages as a function of time.

            Confectionery

This Kransekake is a traditional Scandinavian baker's confection. Confectionery is the art of making confections , which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections. [2] Bakers' confectionery, also called flour confections , includes principally sweet pastries, cakes, and similar baked goods. Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of ...
