What tells electronics what to do?

I know circuitry is made up of resistors, capacitors and all that other stuff, but what actually instructs the machine what to do?
what is the prgrammin written on?
 
In alot of circuits have logic chips (computer chips) that instruct an electronic circuit what to do.
each specific type of chip has its own special function and by wiring them together in a predetermined way produces specific outputs.

for example: if your house alarm is on and someone opens a door it will actiate / deactivate an input to the chip and this will change the output from the chip which will turn on your alarm.

another type of chip is the PICAXE which is a programmable version of a logic chip. the picaxe can perform a complex set instructions that would otherwise have to be performed by many logic chips.

hope this helps
 
circuits do what they do because of the values of the Rs, Cs, transistors, and how they are interconnected, and on what the input(s) are. They are not programmed to do what they do, they do it because of the various laws of electronics, like ohms law.

But some circuits are controlled by a controller of some sort, as doing the same job without the controller would involve a more complicated design. This controller, or microcontroller, or microcomputer, or microprocessor is programmed in any one of a number of languages, like C, perl, basic, or in machine language.

A transducer converts what you want to control (pressure, temperature, position, light, etc) to an electrical quantity so that the electronic circuit can control a motor, heater, etc to make adjustments as required.

A description (PDF file) of a box containing a good variety of transducers and signal conditioning circuits is found by the second link below.
 
well im guessing it will have to be the programming which most likely will be in either C or C++
but there are other programming languages out there.
