I need help. (Rookie turning Pro ..... :))
I am busy building a project where I use the Analog Pin (Mega2560) to read a voltage from a sort like voltage divider to use as information to convert it to a weight (strain gauges).
The datasheets show 1023 represent 5 Volt. If I use the Mega on my computer this is true. However when I connect my Mega to my project, 1023 represent 3.56 Volt.
How can I solve this?
I have tried: 1. Stabilizing my power sources with caps, this did not help. I am using a standard Arduino 5v Power supply that provide 5,3 Volt. 2. Measuring total current delivered, but it is still below the limits.
