![]() ATmega programmers come in all kinds and with range of different functionalities.Sander electronic Sparkfun Preisliste 05/2011 EUR/Stück inkl. Well, you will need yet another equipment for that. Last but not least, you might not only need to connect your board to a laptop, but as well to program the ATmega on it. You name it we have it, in all price levels and from range of renowned and a bit less renowned producers! ATmega programmers There is a range of controllers allowing for this conversion - starting with the class, quality and reliability of FT232 by FTDI through PL2303 through CH340. However, for the development boards, what is the most probable is that you will be playing with straight 4 pin TTL connection. The two most used standards of transmission are RS232 and RS485 - often served by a popular 9 pin DB connector. However, back in the day there plenty of standards used for communication and interestingly most of them are still used, even though maybe not in such popular uses. ![]() We are all well used to the USB ports and it is not surprising by all means. USB convertersĪnother "difficulty" in connecting and in general getting around with your new Arduino or any other controller might be connecting it to your PC or laptop. The easiest way to go about it is to get a bi-directional making it universal and easy to connect the circuit both ways - from higher to lower voltage and the other way around. ![]() And that is where level converters come into play. To make them "talk" to each other you need to bump up the signal or lower it down. Microcontrollers and peripherals often work on different logic levels - that is a 1 signal is indicated by a 3.3V in some circuits and by 5.0V in other.
