Of the day's crop — heavy on shorts, hashtag spam, and generic "5 project ideas" listicles — this one stands out as an actual buildable project with several distinct technical layers worth learning.

An analog clock face rendered on a 0.96" I2C OLED is a surprisingly good teaching vehicle. The display is only 128×64 pixels, so drawing smooth-sweeping hour, minute, and second hands forces you to think about trigonometry in embedded code (converting time to angles, then to x/y endpoints with sin/cos), partial screen redraws to avoid flicker on a slow I2C bus, and timekeeping accuracy — the Arduino's millis() drifts, so you'll either learn to live with it or graduate to an RTC module like the DS3231.

The rotary encoder input adds another useful concept: reading quadrature signals, debouncing, and building a small state machine for setting hours/minutes without buttons. Encoders show up everywhere in real hardware (3D printers, synths, industrial panels), so it's a transferable skill.

Code With TJ is a small channel (under 3k subs) doing focused, single-project Arduino tutorials — exactly the kind of creator worth supporting over the low-effort shorts flooding the rest of today's feed.
