LED driver is an electrical device. It is used to regulate power to a single LED or group of LEDs. In other words, it controls the amount of current and voltage supplied to LED light. It includes pulse width modulation circuits for the purpose of dimming.
For better brightness and long life, a LED driver is recommended to be used in conjunction
The LED driver is an electrical device that regulates power to a string of LEDs. The electrical properties change with temperature and regulation of power is necessary to get an constant output power. LEDs have the risk of failure as it can become too hot and unstable if not properly driven.1 watt LEDs has the advantage of small size and point brig
This module can be used as line sensing, light or fire sensor. It can also be used for line following purpose and obstacle detection. IR LED in the circuit emits IR rays. When an object or white surface comes in front of the module, some rays are reflected back and are collected by the photodiode. A NPN Bipolar transistor is used as a switch t
