HiLetgo 37 Sensor Assortment Kit for Arduino & Raspberry Pi - 37 in 1 Robot Project Starter Kit

This 37-in-1 kit is a fantastic value. Essentially, you get to buy these pieces at wholesale prices but you only get one of each piece instead of buying in bulk. This kit contains numerous sensors and other devices (such as tilt switches) that you can use with your electronics projects. The pieces arrived in a nice, segmented plastic carrying case, unlike some competitors' kits which do not have the separate compartments in their packaging. There is a handy photo guide to tell you which part is which so you can find your parts quickly. The parts arrived in excellent condition without any bent pins or missing components, and while I have not tested all of the parts, the ones I have tested work perfectly, as expected. I am a university professor and I purchased this kit to test for using in a class that I am teaching in the Fall, and this kit passes the test. It will become part of my course in the Fall.

Top scores all round - am still amazed at the variety and choices of components in this set. All are breadboard friendly and all are of good quality construction. It quickly brings a wonder of what could be combined with what, just by looking in the box. The box itself is no flimsy bit of plastic, it can go forward to store resistors, capacitors, wires etc after the parts have been used. Most sensors are literally plug and play, no libraries to install. They more than beat salvaging from old broken electronics for the ease of use and construction quality. Thoroughly impressive, from the 24hr delivery to the types of sensors included! The video shows the unboxing, initial thoughts and an example use of the tri-colour LED.

I have not yet started using these and plan to update reveiw once it do. However my first impression is rather negative. While they arrived in a sectioned plastic box with a paper 'guide' that should show what each component is, they were very mixed up in the box (not matching the pictures) and individual components don't appear to have part numbers on them (at least not in a clear way) so it is somewhat difficult to ID which is which just from little pictures. I searched the HILetgo site looking for documentation and didn't find it. I did find that the part numbers on the cardboard insert match google searchable part numbers for compatible components - I will have to use other manufacturers documentation to learn how to use each (pinouts etc). Documentation would go a long way toward helping make these useful for beginners.

It has a cheap assortment of basic modules, mostly basic sensors, and while not recommended for serious projects, it's a good entry-level item for exploration. The construction is sub-par at best so expect at least 1-2 of them to be DOA and will most likely be LED ones. You get what you pay and the price is right if you don't care too much about quality or possibility of a few of them being DOA. There are no instructions or schematics so you're not sure which are 5V tolerant and which won't function correctly UNLESS they get 5V. The good news is that you can find some basic information or tutorials for most of them and most of them are so simple it's a single analog or digital signal.

Quality is good, acceptable performance, and good price.

The sensors are great but the position of each sensor was located in the wrong position based on the layout chart. They were all in the wrong position which shows very sloppy quality control. It appears that this may be normal with your firm since you do not take pride in making your customers 100% satisfied. You could do much better if you activated quality control.

Very poorly packed with no labels on pieces and no guidance to the arrangement of pieces. The only sensor I tried started burning when inserted in the breadboard layout which was a startling discovery. That said, I can’t recommend using any of these sensors. Never had this experience before with my mass amount of Arduino parts.

Other reviewes showed subpar quality, but I did not have any issues. Bought this as a learner kit just so I can play arround and get comfortable. I have hooked up almost half of these so far while playing around and have not found a bad one yet.
