Having difficulties adjusting volume via PWM
I think some of you are assuming the OP is doing this the way you'd do it, i.e. with a table of sine values being output via PWM. As I understand it he/she is simple outputting a...

ESP8266-01 with python for mqtt
I was talking about the community forum, and, if the OP was to look at running the entire project on the ESP, then the serial questions probably evaporate.

Not quite sure why you want to install Python on your ESP. or why you want to use another Arduino to talk to th ESP, considering it can run the Arduino "system" anyway. I have, in...

ATmega32 trying to use a speaker, but volume is way too low?
  "(tried microsecond too)" Even if the speaker can cope with 1MHz (or 500kHz, depending on what you actually mean), I doubt that your ears can(unless, of course you're a...

No. More likely to be somewhere in the 10 to 20 pF range.

Just the mention of tag strips make me go weak at the knees with nostalgia. I'd completely forgotten about their existence.

Photo diode response time varies drastically with LED.
I think we need to see your circuit. I find it hard to imagine the diode itself would have such a delayed response.
