I received my developers kit yesterday and have been working with the hardware and software and things have been progressing quite well.
I tried connecting the ultrasonic sensor with the included inline voltage regulator and was getting a reading of 255 on the display. I checked the voltage from the regulator with a digital multi-meter and got a floating reading around the 1 volt range. I then connected a LM 7805 5 volt regulator and confirmed a solid 5 volt reading. i used this set up along with the ultrasonic sensor and everything functioned correctly.
Could I have gotten a bad voltage regulator with my kit? I'd like to use the provided regulator since it is a little more compact and streamlined than the 7805.
(Assuming use of port D0 and D1)
1) Ground = Black wire to D0 black pin (regulator)
2) Power = Red wire to D0 red pin (regulator)
3) Trigger = white wire to D0 White pin
4) Echo = green wire to D1 White pin
it should be reading 5v. Does the red LED light up when connected? I would say try using different digital ports to see if you get a different or the same reading, but as you have tried a 7805 reg which read correctly I don't think it's going to make a difference, but you could try.
If this is the case, you can submit a warrenty claim by using the Contact us link and copy and paste the URL link of this tread in you in to your message, and if it is indeed faulty EZ-Robot will send a replacement
Sorry I can't be much more help than that.
I was told that I need to post the problem on the forum in order to make a warranty claim. I can usually find a solution to my technical problems by searching various forums so I don't end up posting on them much.
That clears things up on how to make a warranty claim.
If the regulator is hooked up in with the Vin and Vout in reverse order the LED will still come on but the voltage output will be wrong, likely a volt or 2 off. It sounds like this could be the case.
Thanks!
