Electronics devices are devices that use electrical circuits and components to perform various functions, such as processing information, controlling systems, or transmitting data. These devices can be found in many different applications, from smartphones and computers to cars and home appliances.
It can be used for:
Home appliances - devices such as refrigerators, air conditioners, and washing machines that use electronic circuits to control their functions.
Wearable devices - devices that can be worn on the body, such as smartwatches and fitness trackers, that use sensors and electronics to monitor various health and fitness parameters.
Overall, electronics devices have revolutionized the way we live and work, and have become an essential part of our daily lives. They have enabled us to perform tasks more efficiently, communicate with others more easily, and access information and entertainment from anywhere at any time.
A very good designed circuit of a stable adjustable DC regulator using IC LM317T. LM317T is a very famous IC and supporting input voltage is from 3 volt to 40 volt DC and delivers a stable output between 1.25 volt to 36 volt DC.
This controller is designed to control small 12VDC electric doors - chicken, garage, gate ets. Have build in 2 timers, for open and close the door, with reversing the polarity. Each timer is adjustable from 0 to 25 sec With build in LIGHT SENSOR with adjustable sensitivity for automatic open and close the door on sunrise and sunset. Have led indication for working timer yellow - in one direction, red - in other direction, green - for active light sensor
