SHILLEHTEK HC-SR04 with RGB Light Distance Obstacle Avoidance, Compatible with Raspberry Pi (Raspberry Pi Pico and Other Models), Arduino Ultrasonic Sensor

It's great that this works with the code from a regular HC-SR04 ultrasonic module but with the added 6 NeoPixels. I made a little project where the NeoPixels change color depending on the distance read by the sensor.

This item is neat but the pins are very short and will barely work with breadboard connectors. The second thing is no instructions what so ever you can go on you tube but there is very little information I was kinda disappointed.

Great product, LEDs are beautiful and ultrasonic works just as nicely as the HCSR04. Nice touch, would recommend this to anyone

I'm still learning the Arduino environment, so I picked this up to continue my education. The functionality is nice, but I am more interested in the details of how to interface, how to program, etc. My impressions:- There are no docs included, so I am struggling to figure out how to make this work. Several of the other reviewers suggested that there are lots of tutorials on-line, and they are correct. However, the tutorials all expect either some minimum level of knowledge, or else leave out critical or important information, like where to find the specific libraries used.- Once I struggled through the tutorials and found one that I could make work, the interfacing is straightforward, though not as 'plug and play' as I hoped. Wiring up the module to my Arduino involves wiring up the module to my Arduino, not connecting some female header to a male header and pressing hard... Ok, I'm capable, I can do this...- After the wiring is complete, getting the program running is pretty straightforward. LEDs flash and numbers are appropriately received for distance. It works!Learning the Arduino environment is fun but challenging, and this module doesn't make it any easier. However, it is functionally pretty cool and does what it is intended to do. Recommended!

Works as expected, really cool add on to the regular HCSR04

This is a fun little gadget, but it doesn't come with any instructions at all, only the device in a ESD bag and that's okay. Instructions aren't needed and I think they would actually make this less appealing based on other items of this type.All the information you need on it is online along with a variety of projects ready to go for just about any micro-controller card.It works by sending out ultrasonic waves and determining the distance to an object by the time before the echo is received, pretty much like sonar on a small scale.You could use it for a robot project that can sense walls, or if you calibrate it and adjust your code, you can make a fairly accurate measuring tool.I tested it out on an ESPP32 controller using a proximity detector I found online. It wasn't hard to wire up and I had a mini proximity detector that would sound an alarm on a little piezo buzzer when the distance got smaller. It was a little like playing "You're getting warmer" as the pitch went higher the closer you got to the sensor.It's a fun little tinkering gadget. It will mostly be something for anyone who likes to experiment with micro-controllers, but you could get several and design your own working robot that would avoid obstacles or map out a room. Lots of possibilities.Everything worked right out of the package after I set up the project and loaded the code.Overall, pretty cool for kids or adults who want to learn coding or general science. Five stars.

If you’re reading this, you probably already know what a HC-SR04 ultrasonic range sensor is, and how it works. This device adds 6 neopixel LEDs (3 in each cylinder) to the sensor, just for fun. I followed the code example that the seller provides in the video, and it worked perfectly. This is a super fun addition to a standard old sensor, and I would normally give this 5 stars, except for one big problem.The backs of most HC-SR04 modules just have exposed header pins that you can connect to using DuPont style connectors. However, this module comes with a JST female connector mounted on it instead of the standard header pins. But it does NOT come with the needed JST male connector. When I try to connect to this using DuPont cables, the JST pins are thinner than standard header pins, and my DuPont wires have a flakey connection. They just don’t stay firmly attached (I had to tape them on, and still flakey). So, if you happen to already have the correct JST connectors in your workshop, then great, but I don’t. Most devices with JST connectors just come with a little connectorized cable to solve this problem. Why isn’t the cable included in this set? I’m knocking off one star for this, because it really makes it difficult to use this if you don’t already have the correct JST connectors.Final Rating: 4 stars – needs to come with a male JST connector cable if it’s going to have a female JST connector socket on the board.
