Physical computing is the act of making machines react to people
Ohm’s Law
Voltage(V)= Current(I) * Resistance(R)

Types of resistors
Resistors “resist” how many electrons flow through a current
-Carbon composite resistors
-Carbon film resistors(Most common)
-Metal film resistors
Variable resistors
-PhotoCell- Not polarized (Can go either way)
-Rheostat
-Force sensitive
-Thermostor Resistor
-Slide Potentiometer

Series circuits- In this circuit there are no branches and thus we have the same current everywhere
Parallel Circuit- there are branches so currents are divided
LEDS-Light emitting diode
Diodes : A diode is a two-terminal electronic component that conducts current primarily in one direction (asymmetric conductance). It has low (ideally zero) resistance in one direction and high (ideally infinite) resistance in the other.
Anode=+, Cathode=-
Breadboards
ATTENTION!!! Avoid removing or changing components o na breadboard whenever the board is powered you risk shocking or dying D:
Transistor
These are used to amplify or switch electronic signals (Digital switch)
