Speed Sensor Documentation
Voltage: 3.3V ~ 5V
Usage: Dynamo speed detecting, pulse counting, etc.
Output:
Digital switch output (0 and 1)
Analog output for sensitivity
Functionality:
Operates using infrared light emitted from the LED and received by the photo-transitor.
As the wheel spins, the light beam is alternately blocked and unblocked:
Block → Unblock = Pulse
Connection to Arduino:
VCC → 5V pin on Arduino board
GND → GND
OUT → Digital input pin
Example: Calculating Speed
Measure the number of pulses over a fixed time period (e.g., 1 second).
Determine the distance covered per pulse (e.g., based on the wheel circumference).
Calculate speed using the formula:
Speed=Time (s)Pulses per second×Distance per pulse

Simple explanation with an extra link for setup. Good job
Description:
Study about the LM 393 speed sensor. What signal does it use? How do we connect it to the ARDUINO?Definition of done:
This issue is considered as done when the above questions are clearly answered
