Great way to learn

I've been doing the 30 days lost in space course on the website. I've reached the days involving the rotary encoder and I've noticed something peculiar. When I went to compile and upload the code for the 7-segment display counter controlled by the rotary encoder, I noticed that a clockwise turn decremented the number and a counter-clockwise turn incremented the number, instead of the other way around as the video explained. All of my circuitry was correct as was my code, since I had copy-pasted, but the discrepancy still existed. When I swiched the connections for the CLK and DT pins on the Arduino, the system worked as it should have. I did some testing on my own comparing the data sheet of the encoder and found that the encoder I was given in my kit has the CLK pin as signal B and DT as signal A, which is opposite from what is given in the data sheet and the lesson video. I'm not sure if anyone else has had this issue, but this means that either the data sheet and the video are wrong and need to be updated, or I my encoder was wired incorrectly, in which case inventor.io should verify with their manufacturers to make sure the components being sent allign with the data sheet. Besides this issue, inventor.io has proven to be a great resource for those interested in microcontrollers and embedded systems, and for that they deserve mine and others' praise.

I've thoroughly enjoyed using the "Lost in Space" robotics kit, and even as an adult have found myself learning a lot.

Had fun! 5 stars

There are other training modules out there but this one is the most fun because it is well documented and has a background story to make it fun.

Fast shipping, great training videos (30 days lost in space). Reasonable quality parts. Great kits for introduction to the hobby.

The tutorials are well written and work fine. the progression (so far) has worked well for me. I'm an adult entering this hobby, so the dry presentation is ok. however, were I a 12-year-old just thinking about electronics, the lack of a developed story line would drive me away. the story line is there but frankly you need an actor. you need a person who thru voice and visual content encourages the "astronaut" to fix their craft or they might die! build a little tension! so my recomendation is that the program is great BUT you need a script writer and an actor to perform the teacher role.

This is a great idea, super easy to get started and follow along with.
