Hey, sorry everyone, I know it’s been a while. But I hope this post will make up for that! Anyone who has done embedded programming knows that an easy way for microcontrollers (like arduino) to connect to a PC is through a serial connection.
Unfortunately, not many computers have a serial port these days, and while are a lot of chips that will act like a usb-serial converter, they tend to be somewhere in the $3-5 range. However, I found one chip, the CH340G, that only costs 40 cents!
