At the heart of the circuit is the OS25B10 transmissive optical sensor with phototransistor output (OC1). Next is the venerable LM393 dual comparator chip (IC1) configured as a simple Schmitt trigger ...

A compact analogue reflectance sensor such as the CNY70 was not used in the Arduino Uno experiments described. Instead, a homemade sensor was assembled using a single infrared LED (IR333C) and a ...

A phototransistor uses light to modulate how much current passes through it. In this part, a voltage divider is implemented using a phototransistor that can sense infrared light. By placing a ...

In this tutorial we will make a prototype of a Digital Taxi Fare Meter using Arduino LM-393 Speed Sensor. This project calculates speed and distance travelled by the taxi’s wheel and continuously ...
