LeetCode is the best platform to help people practice solving coding problems and prepare for technical interviews. The main users are software engineers. LeetCode has over 1,900 questions covering many different programming concepts.
Based on our record, LeetCode seems to be a lot more popular than Adafruit. While we know about 515 links to LeetCode, we've tracked only 47 mentions of Adafruit. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
Assuming you don't heed my warning and don't mind your friends beating you to pulp, I'll help I've seen usb widgets that can control electrical things. I think I was a power strip that can be so controlled at adafruit.com. Likewise, I built a robot whose sensors and motors were controlled via usb. This was before the Raspberry Pi's, so I used a ITX board (small form PC motherboard that was running Linux). Source: 7 months ago
If you want to get into embedded programming I'd start at adafruit.com. Source: 11 months ago
Professional eval systems can be quite good, but what I'd recommend is going over to adafruit.com. They have a massive amount of small embeddable boards, as well as i2c peripheral boards when you just need that extra function. They are very easy to prototype in CircuitPython but can also be programmed with Arduino. I know you want to avoid Arduino, so what you want for a more professional environment is...

Adafruit.com is an online store that sells all of this stuff though you can find everything much cheaper on alibaba, ebay and others. Adafruit is host to a whole library of projects and tutorials with comprehensive instructions, code and images. Source: 12 months ago
Many of the suggestions here fit those cases: the PI, the Arduino. I'd like to recommend that you look at the controllers from AdaFruit. I've seen that they do a substantial amount of work to ensure that their controller boards work well with the chips and displays that thye do. Source: about 1 year ago
For those who already know, this is just a reminder, but for those who don't, every week Leetcode has a special contest where a lot of developers try to solve 4 code challenges in a row at 1 hour 30 min. - Source: dev.to / 30 days ago
Firstly, solve some common data structure problems with it. Implement some data structures like arrays, linked lists, stacks, queues, etc. You can check common problems on LeetCode, Hackerank or some other resources. - Source: dev.to / about 1 month ago
I did some traveling around the western US in late 2022 to take stock of where my life was and where I was going. During that time I decided that I would go all-in with my coding education, and committed to learning the remaining material listed on those bootcamp syllabi that I had not yet studied – namely, connecting the pieces of the MERN stack; learning about automated testing and data structures & algorithms;... - Source: dev.to / about 1 month ago
Practice Regularly: Utilize coding challenge platforms such as LeetCode and HackerRank to practice coding regularly. Additionally, websites like Project Euler offer mathematical challenges that can sharpen your problem-solving skills. - Source: dev.to / about 1 month ago
As a self-taught dev, learning the ins-and-outs of Python usually happens as I am solving problems on leetcode or writing random programs in replit. This post is more for myself to remember what I've learned. If you're still interested in reading, then I hope this helps you! - Source: dev.to / 3 months ago
