Dashboard dei sensori in tempo reale

A dashboard shows fresh sensor data that keeps updating. The trick is refreshing the value smoothly without distracting flicker. 📊

Print fixed labels like Temp and Hum once in setup. They never change, so there is no reason to redraw them every loop.

In the loop, move the cursor to just the value area and reprint only the number. The labels stay put.

Calling lcd.clear() every loop blanks the whole screen, causing a visible blink. Avoid it for fast updates.

Instead of clearing, reprint the number at the same spot and pad with spaces to erase any leftover digits.

Humans cannot read a value that changes hundreds of times a second. Update the screen only every few hundred milliseconds.

Time the refresh with millis() so your board keeps reading sensors while it waits, instead of freezing on delay.

Print a small unit like C or % right after the number so anyone glancing at the screen knows what it means.

Show temperature on row 0 and humidity on row 1. Each gets its own cursor position and value update.

For the smoothest look, only reprint a value when it actually changed since the last update. That stops needless redraws.

Fixed labels, targeted updates, and a timed refresh combine into a clean, flicker-free dashboard on a tiny screen. 🎉

Your dashboard blinks annoyingly every loop. What is the best fix to stop the flicker?

You print labels once, overwrite only the changing value, and time refreshes with millis to build a smooth live dashboard. ✅
