Dear Anthony,

Thanks for the info. Does the cable of the Adafruit solar panel need some adjustment (or additional jack), or one can plug it in directly?

With friendly greetings,

Arnoud

Dear all,

OK. I have correct distance readings right now of my sonar. Thanks for helping. Next step is to save the readings into the SD card. I tried the code of Rich abuve, but in my case it is not working. Steve, can I ´incorporate´ the sonar scetch into the´simple filé´ example posted on the forum? Any tips on how do that ? I was able to save analogue measurement values of temperatures with the mayfly earlier with the simple file code, but no clue on how and where to include the section of sonar.

Thanks in advance,

Many greetings from Asuncion, Paraguay

Thanks for the quick reply. Indeed, I was probably erroneously connecting the PWM output (2) instead of the serial (5) to the Mayfly. I will give it a try this week and keep you informed. Thanks for the help…

Dear all,

I have the same set-up of Maxbotix sonar with Mayfly as Steven. I did some trials first with my arduino and analog signal reading which was succesfull.

Now I trying the serial code available on the enviroDIY website, but readings are 0 mm. I hope following questions may help me to get succesfull measurements:
1) In the code the pin 5 is D5 of the mayfly?
2) The GND and 3.3V of the D pins is used?
3) To the pin 5 of the mayfly I connect the signal of output 2 (PulseWidth) of the maxbotix?

Any other checks I can make to resolve this issue? Thanks in advance.

Have a nice weekend.

Arnoud
