8 Unique Sensors for Arduino Microcontroller Boards - MSNArduino pulse sensors have a small infrared LED that is placed on a finger to reliably read the pulse of a human, providing an analog output that is easy to work with and read.
I made this Arduino project that allows to turn ON and OFF LEDs using a cheap IR remote control as a preparation for the next big step: disassemble my girlfriend’s chinese LED lamp and replace its ...
The music controller consists of 64 LEDs positioned underneath the display to provides visual feedback s the user touches the screen and work independently from the sensor array allowing you to ...
Unlike many similar interactive LED matrix displays that are digital in nature (because it’s a lot easier), this design is pure analog, using many, many op-amps.
By using an array of red and near-infrared LEDs, a research team developed an optically based, non-invasive system for 2D mapping of the blood oxygen saturation across a patient ...
