Wenn das für dich ok ist. Ich will dir nicht in die parade fahren!

[NyFAZ]

Aber sicher ist das okay

Ich würde die sachen halt gern zusammen verkaufen. Sind dann ausreichend teile für zwei basteleien + fehlversuche. ^^

Klingt gut für mich [emoji16]

@Nickel
Ich würde dir die Teile gerne abnehmen.

Hallo, Freunde des elektronischen Motorsports.
Ich habe daran gedacht und den Code mal rausgekramt.
Pinbelegung ist für ATTiny85. Verbesserungsoptionen könnt ihr hier gerne diskutieren, ich halte mich jedoch raus.
Bin kein begnadeter Programmierer und es reicht mir so, wie es ist

Code: Alles auswählen

/*
   ATTiny PB3=Eingang RFID
   ATTiny PB1=Ausgang Relais
   ATTiny PB0=Ausgang LED

   ProgrammMode = LED AN
   Slave1 programmiert 1xBlinken  (Freq 1Sek)
   Slave2 programmiert 2xBlinken  (Freq 1Sek)
   Slave3 programmiert 3xBlinken  (Freq 1Sek)
   Speicher voll: 3xBlinken       (Freq 300ms)
   Zwei Ausgänge sind über, eventuell OLED als Anzeige
   Aktueller Stromverbrauch gemessen mit Multimeter Metex M3900: 0,040 A
   Ohne Sleepfunktion

Danke fürs einstellen des Codes.

aber... was ist das für ne LIB?

#include "ReceiveOnlySoftwareSerial.h"

die kenn ich nicht. muss ich mal im www nach schnöfen wo ich die finde.

Hallo Galo,

wenn die nicht findest, schrei einfach.
Ich schicke sie dir.

[GalosGarage]

komm ich bei zeiten gern drauf zurück.

Wenn ich mal wieder im Büro bin werde ich hoffentlich an Dich denken
