Keep the pulse down to microseconds and don't use a transducer frequency UNDER 40khz. 1 year ago Maybe try restarting Arduino. Unfortunately, vibrator motors REALLY chew up the battery life!! You should look into marketing this idea commercially. Yours would work for them if it vibrated or something like that. Copied and pasted the code (retried several times) as listed on this post, but still get the same error when Verifying: C:\Users\Paul\Documents\Arduino\sketch_dec30b\sketch_dec30b.ino:1:23: fatal error: i2cmaster.h: No such file or directory Sonar Collar for Blind Dogs features a collar intended for use with visually impaired canines.

The thing they has in common was very short battery life. Start by soldering the male header pins in a way that the PCB can easily clip onto the Arduino.

Take your time soldering in the connections making sure that you don't create any short circuits.
