-Optionally, GPIO 17 can be used to drive an NPN-transistor (BC337-40) that pulls a p-channel MOSFET (IRF9520) to GND in order to switch off 5V-current. Transistor-circuit is described [here](https://dl6gl.de/schalten-mit-transistoren): Just have a look at Abb. 4. Values of the resistors I used: R1: 10k, R2: omitted(!), R4: 10k, R5: 4,7k

 ## Starting Tonuino-ESP32 first time
-After plugging in it takes a few seconds until neopixel indicates that Tonuino is ready (by four (slow) rotating LEDs). If uC was not able to connect to WiFi, an access-point (named Tonuino) is opened and after connecting this WiFi, a [configuration-Interface](http://192.168.4.1) is available. Enter WiFI-credentials, save them and restart the uC. Then reconnect to your "regular" WiFi. Place to favourite RFID-tag next to the RFID-reader and the music should start to play. While the playlist is generated, fast-rotating LEDs are shown.

 ## Interacting with Tonuino
 ### Playmodes
 It's not just simply playing music; different playmodes are supported:
 * single track
 * single track (loop)
-* audiobook (single file or playlist; last play-position is saved)
+* audiobook (single file or playlist; last play-position (file and playlist) is saved)
 * audiobook (loop)
 * folder/playlist (alph. sorted)
 * folder/playlist (random order)
