PING meter (ping mérő)

Ez a videós tartalom 2024 márciusában jelenik meg a YouTube csatornámon. Ez a kód majd az akkor megjelenő tartalmat támogatja.

Az előbbi képe pedig a 240x240 pixeles kiejlzőt használja a ping jelzésére. A kód 1:1 ben működik kijelző nélkül és a D3 portra mutatós műszert kötve (kb. 3.2Volt felel meg 60ms ping értének)
