Hi folks, I bought this sensor: https://shop.pimoroni.com/products/ultrasonic-distance-sensor-breakout [USDBkt_IMG_1462] and want to add it to a Raspberry Pi 3 robot buggy. The info says it uses pin 4. I have the small I2C Breakout Garden [Breakout_Garden_pHAT_1_of_5_400x400] but I really want…

If your not using any other Breakout Garden boards, then no you don’t need the Breakout Garden Mini. I was assuming (maybe incorrectly) you already had one and had some breakouts in it. That looks like it should work Ok. Near as I can tell from the photo’s anyway. I have a couple of two wheel rove…

If it’s i2c my best guess is as follows V is V+ likely 3.3v D is Data SDA C is Clock SCL S is I don’t know? INT maybe? G is Ground. There is this that plugs into the breakout garden [image] I2C Garden Extenders (pack of 3) – Pimoroni Store Use any I2C breakout with our Breakout Gar…

Thank you very much K @alphanumeric . That helps no end! I now have a soldering iron so I’ll use the method you’ve explained. Thanks again. Anne

If you use the female to female jumpers, you could remove the black plastic shell from one end. Then just solder the connector to the pads on the sensor. No having to cut and strip the ends. If you lift the little locking tab up with a pin or needle you can slid it off. Do it carefully and you can r…

Ops, somehow I missed this bit. This breakout is fully compatible with Pimoroni’s [breakout garden], so you can plug it into any of the I2C connectors and use it on GPIO pin 4. It is a single pin, 3.3V sensor breakout. So the Ping and the Echo are on the same pin. Code it using standard HC-SR04 c…

Thanks very much for your help K @alphanumeric . I am learning so much by doing this and hope to be able to show you a robot buggy that avoids walls with the USD sensor, on Twitter, in a while. Thanks again. Anne

I have an older version of that sensor that was for the RoboBit Mk2. I hooked it up long enough to make sure it was functional, then got sidetracked on another project. My plan was to use it with an Arduino and have it on a servo. Have it work kind of like a forward facing radar. [image] A…

Thank you K that’s interesting. I think one of these will do the job for me as the USD sensor is a breakout designed for the garden. https://shop.pimoroni.com/products/breakout-extender . [Breakout_Extenders_4_of_4_1024x1024] Thanks, Anne

The one I linked too above has both bits. One plugs into the breakout garden > Jumper > other end plugs onto sensor. The one you linked too will still work. You’d just solder your wires to that extra row of solder pads on the breakout garden. Or solder a header to the breakout garden and plug your…

[image] Aren’t these extenders just like the slots on the breakout garden - so with the sensor I’ve got (see image at top) I can do without the garden all together? I only need one slot. Then I would need a female to male jumper to go from the extender to the motor controller’s pin 4. See image of…

[image] Lilac jumper (on the left of the image) in pin 4 is ready to go into the connector/extender to the sensor.

Re: Build pics They are so interesting! Thanks for letting me in on them. I might need to refer back to them sometime to look at how you’ve done things. Anne
