Timer interrupt method for event-driven sketches. Arduino Playground is read-only starting December 31st, Keep in mind this example is. Option to interface with all but the SRF06 sensor using only one Arduino pin. For more info please look at this Forum Post. My guess is that your goal is to have both sensors ping as close to the same time as each other, then print the results, and do that once per second.

Rob Tillaart Nederlandse sectie – http: Anyway, I have a bit of a problem with your sketch. Option to interface with all but the SRF06 sensor using only one Arduino pin. Features Jewping.h with many different ultrasonic sensor models: Jujo Full Member Posts: Your example is for Arduino IDE 1. However, standard ping methods are all supported.
Really, you should try to avoid using a delay at all cost, and lirary sketch is built to not need to use it. Maybe that ends up with the endifs wrong??
Ping sensors consistently and reliably at up to 30 times per second. I will can’t wait to try it out! Allows setting of a maximum distance where pings beyond that distance are read as no ping “clear”. Two sensor example [Select]. Doesn’t use pulseIn, which is slow and gives incorrect results with some ultrasonic sensor models. So ms are lost waiting for new sensor reading to avoid the echo.
SOLVED! Newping.h Library
newpin.gh It appears you want to only do a ping once a second, so set pingSpeed to and remove the delay. The NewPing library totally fixes these problems, adds many new features, and breathes new life into these very affordable distance sensors. Allows setting of a maximum distance where pings beyond that distance are read as no ping “clear”.
Here is the modified sketch that I tested with my 2 sensors.
AWOL on May 17, I just got 4 of those sensors, and I have one hooked up at home. I have almost 30 ms for Arduino to do other things and after restart next reading. If you don’t print in the serial monitor the time is always under 10 ms. I tried your sample sketch on IDE 23 and 1. Hi Tim, Great work!
Next, I modified the sketch to print the output from the sensors and also added a delay to slow the data to a readable level. But in my experience a normal algo in Arduino, without too much serial monitor librarh, take ms. I’m not sure if at this point development for old versions is really required.
Timer interrupt method for event-driven sketches. The playground is a publicly-editable wiki about Arduino. Sources for Electronic Parts. I start reading the first sensor, the second, the third and the forth. Added support for non-AVR microcontrollers. New in version 1. Background When I first received an ultrasonic sensor I was not happy with how poorly it performed. Great Lakes Brewing Co.
