Hey all,
Looking to mimic this project using the ESP8266 Arduino library: https://www.hackster.io/middleca/wi-fi- ... 8&offset=0
Before getting into the software bits, there is an upfront hardware difference between the two boards. The Photon provides DAC1 for analog output, while the ESP8266 has no such onboard support.
Given this difference, I'm wondering how to accommodate for the missing hardware. It is my understanding that the ESP8266 supports analogWrite through software. Would that be sufficient?
Or, should I be looking at external DAC chips such as: https://www.sparkfun.com/products/12918
Any guidance/support is greatly appreciated! I am very new to hardware hacking and have found this forum extremely informative thus far.
