Day 2 of Mechatronics

Today was introduction to a multimeter (MM), probes (what attach to the MM), reading schematics and different sensors that control resistance. 

Multimeter:

We learned the uses and settings to a multimeter to measure voltage in both AC and DC, resistance across a current, range and continuity (seeing if a circuit is complete).

Sensors of Different Kinds:

We were introduced to some of the resistance controlling sensors of different kinds ranging from potentiometer (adjustable resistance), force sensitive, light sensitive, heat sensitive and others. We used the MM to measure their difference when put under the conditions they were designed for to see the change in resistance.

Basic Schematic:
We then had to use our new knowledge of reading a very very basic schematic to light up an LED on a bread board.
