Description:
This simple Digital-to-Analog-Converter uses an R2R resistor ladder to generate an 8-bit analog signal from 8 digital outputs from an Arduino.The signal is amplified for a small 8-ohm speaker using an LM386.nnDAC plans here:nhttp://blog.makezine.com/archive/2008/05/makeit_protodac_shield_fo.htmlnnLM386 amplifier:nhttp://www.reprise.com/host/circuits/lm386.asp
