pxt-sonar

A PXT package to use sonar sensors (ping) such as the HC-SR04

Usage

This package contains a ping block that can return the distance to an obstacle detected by the sonar.

sonar.ping(DigitalPin.P1, DigitalPin.P2, PingUnit.Inches);

Charting the distance

Use the plot bar graph block to visualize the distance reported by your sensor.

basic.forever(() => {
    let p = sonar.ping(DigitalPin.P1, DigitalPin.P2, PingUnit.Inches);
    led.plotBarGraph(p, 0);
})
