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.

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.

Product comes with no documentation. This is OK, if you know about the KY-xxx system: alot of documentation online. Second, expect some modules to NOT work. 5 did not work and 2 others I am not sure. I still consider this a bargin; If you know how to test each module, you will too.

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.

Good for beginners yes!

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.

For the price, you'll not be dissatisfied. Even if you never try some of the modules, they are something like 50 cents each, so just donate them to a local Maker club. The plastic storage box is a nice touch. I suspect I'll find uses for some of these that I'm not yet imagining, and they're on hand, so I'm much more likely to want to "play". I like just looking at them, and appreciating the amazing ingenuity that has gone into developing and manufacturing them. Nerd "jewelry", anyone? ;-) The fast Amazon shipping sure beats waiting weeks for orders direct from China.

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.
