CAN is a message based protocol, designed specifically for automotive applications but now also used in other areas such as industrial automation and medical equipment. text/html 2020-07-20T12:00:00+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.robolabor.ee/homelab/en/examples/communication?rev=1595235600&do=diff Communication [Data interfaces] With microcontrollers it is possible to control actuators, read the values of sensors and many other stuff, but always stays the need for connecting all kind of devices, which does not allow to communicate by sending simple digital signals. The reason may be: there are too many control signals needed to control the device or there is too much data to be sent.

Input/output pins are microcontroller contacts. They are so called “legs”. A digital signal is received and transmitted through them. If a pin is configured as input, the status of switches or simple sensors connected to the pin can be received. When a pin is configured as output, it can be used to light LEDs or control electrical equipment. text/html 2020-07-20T12:00:00+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.robolabor.ee/homelab/en/examples/display?rev=1595235600&do=diff Indicators and displays [Displays] One of the easiest methods for being convinced that the microcontroller is functioning is adding a code to the program which blinks a LED or LEDs during certain activities. Quite often it is not enough, because it is necessary to forward more information than it is possible by using LED and some applications require user interface where text or numbers are displayed.

Koodrid on seadmed mida kasutatakse liikuvate või pöörlevate objektide positsiooni või asendi mõõtmiseks. Objekt võib olla mootori võll, roboti ratas, seadme nupp, jms. Ka kuuliga arvutihiirtes kasutatakse koodreid mis registreerivad kuuli pöörlemise. Koodrid on tegelikult üks andurite alaliik, kuid robootikas on nad nii laialt levinud, et väärivad eraldi tähelepanu. Koodreid jagatakse funktsioonilt lineaar- ja pöördkoodriteks.
