Ping))) Ultrasonic Distance Sensor with Graphical Debug Demo
Description The Ping))) object provides the distance from the sensor connected to an I/O pin through a 3.3k to 4.7k resistor. The object returns the distance in microseconds, or a 0 value if missing or bad sensor. The example uses smart pins and can be replicated for as many Ping))) sensors as needed. The values […]
Using Smart Pins to Measure Frequency Output of TSL235R Light-to-Frequency Sensor
Description Through the use Propeller P2 smart pins it is easy to measure the frequency, periods and duty cycle of input signals. This Quick Byte shows how to monitor the output of a TSL235R Light-to-Frequency Sensor. The output of the TSL235R Light-to-Frequency Sensor is a square wave that varies from 0 Hz (total darkness) to […]
