but no obvious place to look for error. Is there guide for switching to this new version?
In the Arduino IDE, use Ctrl T or CMD T to format your code then copy the complete sketch.
Use the </> icon from the ‘reply menu’ to attach the copied sketch.
ok, tomorrow.
Don't you get something like below in the output pane? In this case I forced an error by removing the closing } of setup().
C:\Users\sterretje\AppData\Local\Temp\.arduinoIDE-unsaved2022017-5952-infumk.qqia\sketch_jan17a\sketch_jan17a.ino: In function 'void setup()':

Are you a robot ? ![]()

you're right
fatal error: ThingSpeak.h: No such file or directory
I do my best.
Yes, it was not finding an include file. easy fix. But with this new version can I make the serial monitor print larger?
Yes. Do this:
- Select File > Preferences... from the Arduino IDE menus.
- Check the box next to "Interface scale; ☐ Automatic".
You can now chose your scaling factor from the % field. However, you might find the alternative scaling adjustment method described below more convenient, since you don't get immediate feedback from your adjustments in the "Preferences" dialog. - Click the OK button.
You can now use Edit > Increase Font Size to adjust the scaling of the IDE interface to your preferences.
yep, thanks
You are welcome. I'm glad if I was able to be of assistance.
