I plugged an.0 into 5v line. the ground is uno ground.
i tried a nano and it to needed define AD_REF_SOURCE AD_REF_256
watch the an.0 connected to 5V drop value. strange? https://youtu.be/iaQez7iDqUc
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
1) Print the value of ADMUX to the GLCD. What is the returned value?
2) Do the same with AD_REF_SOURCE removed from your source code. What is the returned value?
3) Please do not hammer the ADC with reads. What is the delay between reads*

as for 3) delay is time between refreshing display. That's pretty fast visually.
sort 1 and 2 later. so easy to make a gauge and scale makes it universal https://youtu.be/INjJM4L19C8

The 5V nano pin measured not 5V
I thought the trig and graphics and my code would be delay enough..but not it seems. Is that good? sarcasm.
I put wait 5 ms in the loop as it has to send pulseout 2.25 ms now.
I set adread to slow also.
seems ok. sorry off thread but just testing scale. surprised how fast it works.

I measured the "5 volts" and my meter says 4.67 V. what can I expect for £1.70 :)
