Introduction to Physical Computing

Physical Computing is very similar to our body.

it is all about communication: sensing signals-> computing and sending commands -> and executing.

For example, we use our ear to listen and then sending signals to our brain to decode and computing what's the responses

and send the command to our vocal cord to output the responses.

the difference is that inside of the human body communication is done through the nervous system or biochemicals.

however, computer communication is done via electric signals. and of course, the human body is much more complex and can't be easily programmed.

if we duplicate what happened above in physical computing it would look like this:

I use the mic to detecting the overall sound volume it is too loud I will start beeping.

the sensors normally are components that can either covert signals into an electrical signal or add resistance

communicating via electrical signals.

sensors that can change electric signals.

pulses resistance or shapes.
