Super cool building project to do with kids to teach soldering and programming
LIKES: good instructions, cool project to work with kids, product description is accurate (what you need to buy in addition to this product). DISLIKES: none to report. HOW USING: I am using this to teach soldering and programming to my nephew. RECOMMENDATION: Yes. This is a pretty cool project to do with an older child to help teach basic soldering and programming.

Would have been nice to know a micro controller was required
Now I’m stuck till I get oneð¢

Great for the self-learned solder-er
I’ve been trying to learn how to solder in order to apply that to another hobby (stained glass). This kit makes learning soldering interesting and fun, and also a goal to achieve. I love that it’s an all in one and that the guide teaches you along the way. I wish I had this when I was in grade school.

Awesome soldering starter kit
I’ve been wanting to get more into hands on electronics and tinkering with hardware, and soldering was something I had never done before. I just didn’t know where to start. Then I found this. It’s a great starter kit. It provides all the components for a little electronic gadget that need to be soldered together to work, among a few other tasks. They provide instructions that are easy to follow, and it doesn’t take too long to get the piece assembled and working. I really like this approach to learning and will be looking for kits like this until I get the skills and confidence to try this on my own projects without the guide of a starter kit.At the price it’s offered it’s a great value. This kit builds out a little musical device.

Not compatible with UNO R4
Uno R4 is not compatible with MIDI Library (yet) because its the first Uno that is 32bit, and all previous libraries were built around 8bit Uno like the R3.

Awesome Arduino piano kit! UPDATED REVIEW!
UPDATED REVIEW: I 3D printed the piano STL files that come as a digital download with this kit. I still haven’t soldered the kit, but I’m getting ready to, so I attached some pictures of the 3D printed piano. It took a full day to print all the piano parts (some need support). I’ve “loosely” assembled the parts, but haven’t fully clicked them into place yet without the circuit board inside, because once you snap them together, you won’t be able to easily get them apart again. The white keys are “pressable” so you can press the underlying buttons on the circuit board.Original unedited review, below:Full caveat, I havenât had a chance to build this yet, but Iâve built lots of Arduino kits, and also built a very similar project from scratch (my own design). Iâll say this kit is awesome. Itâs very well made, includes all the parts seen on the sellerâs page, and has very, very good documentation online (40 pages + schematics, etc.). The included one-page instructions are just the tip of the iceberg. On the vendors website youâll find downloadable sample code, very in-depth instructions of how to assemble and program, as well as STL files so you can 3D print your own piano case (with pressable keys and everything). You need to have your own Arduino UNO, but otherwise this kit has everything.If you are interested in this, I suggest going to the productâs support website and reading some of the instructions and documentation for yourself to help you decide. This is a pretty highly capable device, with onboard buzzer as well as 3.5mm audio jack and speaker terminals. It can act as a standard âpianoâ (e.g. press the key, make a sound), or as a sequencer, so you can play back saved tunes (e.g. more like a music box). It has a nice RGB programmable neopixel light strip for some nice ambient lighting. The only real limit here is the relatively small memory in the Arduino. This kit even includes some parts like a light-dependent resistor, so you can program some of your own effects with it (but their sample code doesnât use it).When I finally build it and print the parts, Iâll try to update this review with some pictures. So far, this is a very cool kit, and has a lot of nice features and functionality for the very low price, currently just under $25. Iâm very impressed. 5 Stars.

Arduino controlled tone generator. Tact switches meh. Decent other controls
== Kit build ==Clear instructions. Include both a simple component card in order, or the full image instruction sheet with ordered parts list.Comes in a simple box with sleeve. A bag for the PCB, resistors, and other components. Four screws are included, but they don’t seem to serve a purpose unless you build something to mount it to.It took about 45 minutes to assemble for an experienced solderer. Order matters a bit as some components are packed closely, and items need to be soldered from both sides. Everything is through-hole.You have to create an account to access the digital assets, annoying. There’s a password policy (5-40 chars), but they don’t tell you until you violate it. Could be a little more convenient, or just throw the stuff on github like everybody else.== Code examples ==I opened the MIDI_GRAND code. It needs the FastLED, MIDI libraries. I see the key LEDs light up, and the LED bar changes when I rotate 3 of the pots. However, it doesn’t seem to initialize as a MIDI device. From the manual it seems to rely on a special MIDI-Serial bridge. I guess this is reasonable as not all Arduinos have a USB device.The next example is the MG_Recordion. This is a basic Piano, and has a full explanation in the comments. It seems to just have an Octave knob, and Volume knob (affects the speaker, and audio jack output. buzzer is fixed). It seems to step through fixed octaves, and the uppermost octave has some ringing which might be undesirable. The RGB LED bar is super bright and needs a cover to reduce the glare.There are a couple sequencer sketches. I found the interface confusing, and unresponsive, but they at least give some code examples.== Conclusion ==None of the example code seemed to use the photoresistor. As little programmable noise maker it seems alright. You get 8 keys, 3 analog pots (plus volume), and the photoresistor to control things. You can use the addressable LED bar as a display for some basic output/status.Negatives are the clicky tact switches, and the overbright LEDs. It looks like they have a ‘mega kit’ to help address those a little bit. It keeps the LEDs inside a case, and provides some larger keys to press on.
