I recall that older OC71, Circa 1965, had a clear gel and if you scraped the black paint off the glass it worked great as an opto sensor. Later they replaced the clear gel with an opaque white ...

IR Sensor Pinout. The IR sensor has a 3-pin connector that interfaces it to the outside world. The connections are as follows: VCC is the power supply pin for the IR sensor which we connect to the 5V ...

The flame sensor module has only very few components, which include an IR photodiode, an LM393 comparator IC, and some complimentary passive components. The power LED will light up when the module is ...

A night lamp project with a relay module, a photodiodes, a lamp, a RGB led and an Arduino. A night lamp and a led only turn on when it's dark. And a LED changes color continuously ...

Mixes RGB LED colors by adjusting PWM signals on the red, green, and blue pins. Controlling the brightness of LED using Attiny85: Demonstrates LED brightness control using an ATtiny85 microcontroller.

Recently applying an intelligent self-curing system to get a feedback from the LED light in order to control its intensity with driving current has attracted so much attention. This study presents a ...

The project demonstrates the basic interfacing of TCS3200 sensor, Arduino Uno and common-cathode RGB LED. Fig. 1: ... Pins S2 and S3 of TCS3200 are used to select the group of photodiodes (red, green, ...

If you know the red, green, and blue components of the light that correspond to maximum reflectance, then you know the color of the object. Their sensor uses a four-lead RGB LED, but we suppose a ...
