With a Arduino Mega, I want to send a "1" to digital output, say D4. The "D" will be static. But the port number needs to change. For example I will have a loop where I increase the integer value of PIN,and send 0 or 1 in a digital write. In the following statement, for a digital...

I am using the stock component. To play more than 1 tone, it seems that one has to add the component for each tone.
It would be nice if one could specify the pitch and duration when calling it.

Thank you. This interplay is what makes the Forum so great.

I am not seeing the MAP function in Version 11.

I have a 12.62 Volt Lithium battery (4S). The voltage goes thru a 5:1 voltage divider to AN0 on the UNO. It consistently uuder reports the voltage. (See photo) For the component, a potentiometer, I am wondering if settings for the pot need to be tweeked. From the photo, the UNO is saying the voltage...

In the attached program, for an UNO, I get the following message when I enable an interrupt "Interrupt for Incrementing minutes". The interrupt is highlighted with a comment. I am wondering if anyone has any comment as to why the compilation fails. C:\ProgramData\MatrixTSL\FlowcodeV11\FCD\...

I get this response: I was wondering if there is a guide as to error interpretation. I might add that if no UNO is plugged in, I only get the last code. I have selected, in Project options, the correct programming port. I am wondering if I have the incorrect version of the UNO. ""avrdude.e...

I would like to use any of these 3 sizes of LCD's, as shown in the photos. I can see a mC labeled SM245TS.
Thanks in advance.

Thanks again. I will try that.
Oddly enough, with the attached program, when I add 2 Buzzer components,
with different frequencies, and test it, I get the same frequency sound.
