There is no OS, you just write a loop of code, flash it, and it runs. Arduino micros are really handy and you can get a 10 pack for like 15 bucks. Also if you are doing anything with pulse width modulation they can't be beat for the price.
Really?!? Wow! I had no idea! What kind of code we talking? Programming or just like shell script level stuff?
Here ya go. (arduino.cc) You can build a board from scratch or buy one. Open source hardware design so there are a lot of chingChong manufacturers and that drives the price down.
I hate to say it but for many electronics, Chingchong is 100% the way to go. They make decent products for a very low price. If you need 100% reliability, not the best choice, but at often 4x the cost of ChingChong version, you can literally buy 2 and have a spare on hand. Plus most shit is outdated in 1-3 years anyways, so spending 4x makes no sense. Hate this disposable world, but hey, don't hate the player, hate the game - AMIRIGHT?
I have to admit that I didn't really know about pulse width modulation so did some reading. Another mind blowing thing. So THAT'S how voltage regulators work! Cool shit man! Thanks for sharing this!
I actually do a lot with modulation, but more in the RF realm and some fiber optic. Not sure yet how / if this could apply or fit in.
Pwm is a important thing to learn about, I would recommend reading up and the lm555 timer as you can do PWM analog and at 25 cents per timer it is a deal.
This (pcsilencioso.com) is a good basic design for light dimming or motor control you can do on the cheap.
