UHR Version 2.2.0 Pegelanpassung Der ESP arbeitet intern mit einer Betriebsspannung von 3,3V. Die WS2812(B) Streifen arbeiten dagegen mit 5V. Dies erfordert eine Pegelanpassung, damit die digitalen Signale fehlerfrei zu den Stripes übertragen warden können. Ohne Anpassung kann es auch funktionieren, muss
