I am trying to get the ultrasonic ranger to work with a custom project. It first worked fine but then the transistor got quite hot and the readings are complete randomness. From a distance of 10cm it reads :
I didn’t really use it at all before this. It was working fine for a bit then I booted up the Rpi again and it started giving me these weird signals before being moved. The reading was being done at different speeds to give the sensors time to read the signals. Am I gonna have to buy a new one:
He’s not talking about two ultrasonic sensors, he’s talking about using the ultrasonic sensor with a different sensor attached to the Grove board.
My bad. He was talking about two ultrasonic sensors.
He appears to be suggesting that you get a spare as Seeed Studios’ stuff sometimes doesn’t work well. (We have seen quality issues with Seeed Studios’ products in the past.)
Please order from a reputable dealer with a good guarantee policy and not some idiot on eBay.
Please understand that neither of us uses a Grove board with our robots. We’re trying to help based on our knowledge of the sensors and what information we’ve heard and read about the Grove board itself.
@cyclicalobsessive asked about different sensors being used together because sometimes there are conflicts between the sensors.
What version of the Raspberry Pi O/S are you using and which version of the Pi are you using it with?
