Practical PID – Arduino Experiment To demo PID theory in action, I picked up an Arduino Uno from my messy drawer along with a GL5528 photoresistor (LDR) and a super bright 5mm blue LED. The experiment ...

Input: an LDR detects when it gets dark. Process: a microcontroller processes the signal from the LDR. Output: the system turns on the street light LEDs.

There is no question that steering wheel mounted controls are super convenient. Reaching all the way over to the dashboard to change a radio station is so 1990’s. An ever-increasing percentag… ...

the systems approach breaks down electronic systems into input, process, and output stages for analysis input uses sensors (LDR, thermistor, microphone, thermostat) to detect changes the process ...
