A simple Digital to Analog converter using a resistor ladder. Resistors can be any two values, where the second value is twice the first one. Example: 4k and 8k. Since this DAC uses 4 pins, its resolution is 4 bits, leading to a step size of 0.3125 volts per bit. So the values which can be obtained come in increments of 0.3125 volts. Example: 0.3125v 0.63v etc.
