Strommessung mit AVR
So was gibt es fertig: MAX472, Shunt, Vorzeichenflag sind bereits "on board". Alternativ für hohe Ströme MAX471.
Spannung per Spannungsteiler an die Plus-Leitung hochsetzen. Danke auch an Reiner für den Tip zum MAX472, werde ich mir mal anschauen. Und überhaupt, Klasse wie schnell das ging ;-) Viele Grüße Stefan

led's ohne Vorwiderstand
LED von 3,2V waeren es 15 LED's. 2. Variante Eine andere Moeglichkeit waere mittels LM2579 und MAX471 eine Konstantstromquelle aufzubauen und dimmbar über ein Mikrocontroller waere es auch noch. Der LM2579 ist für maximal 3A ausgelegt, somit müsstest du zwei getrennte Netzteile aufbauen. Die
Der MAX7219 kostet ja auch nur 7 Euro.
