![]() ![]() It accomplishes this through circuit analysis and voltage division.Īrduino is an open-source hardware platform, where you can program a microcontroller board to read in inputs, light up an LED when you push a button, or even to run a motor for a robot! The microcontroller is part of the Arduino board, and to feed it a set of instructions you need to use the Arduino programming language and its Integrated Development Environment, or its Web Editor. This circuit converts high/low voltage outputs (binary weights - with 1 referring to 5V and 0 referring to 0V) to an analog voltage (such as 4.6777). We are going to be designing a Digital to Analog system by building a circuit called an R-2R ladder. If you want to know more about DACs and their applications, I've talked a bit more about that here. Because I've been pretty intrigued by DACs and how they really work, I wanted to go ahead a build a simple implementation of it! A DAC is a system which converts a digital signal to an analog signal.
