Here, an output value of 0 is zero and an output value of 4,095 is full-scale, where the full-scale value is determined by the reference voltage supplied to the VCC pin. Here’s a simple sketch for the ...

Of course, you could get rid of the nice-sounding DAC chip and output 5-bit PWM directly from the ESP8266, but aside from being a nice quick demo, it’s going to sound like crap.

Despite a wealth of tutorials for setting up and writing code for the ESP8266 WiFi module, there has not been much of anything on programming this cheap wireless module with the Arduino IDE. Finall… ...

The Extended DAC Shield is a high-speed, high-precision, eight channel, -10V to +10V analog output shield for the Arduino. The design will be open source with schematic, layout, and source code ...

Hard-drive based media players aren't anything new, but hifi equipment actually built from old drives are somewhat rarer. At Hifiduino they're using an Arduino microprocessor to construct a DIY ...
