 This is an Alarm Clock (Radio) based on the Arduino Uno in combination with a MAX7219 LED-Matrix, Relay-Board, DS3231 RTC and a standalone Radio/Audio Module.
 
 Note: This Project is under heavy development at the moment.
+
+## Wiring
+
+Image how to wire the project will follow.
+
+###### LED-Matrix:
+
+| LED-Matrix | Arduino |
+| -------- | -------- |
+| VCC     | Vin/5V+   |
+| GND     | GND    |
+| DIN     | GPIO13 (HSPID)   |
+| CS    | GPIO 10  |
+| CLK     | GPIO14 (HSPICLK)  |
+
+
+###### RTC DS3231:
+
+| DS3231 | Arduino |
+| -------- | -------- |
+| 3,3V | 3,3V |
+| GND | GND |
+| SCL | GPIO5 |
+| SDA | GPIO4 |
+
+
+###### Relay-Module:
+
+| Relay-Module | Arduino | Type |
+| -------- | -------- | -------- |
+| VCC     | Vin/5V+   | Power |
+| GND     | GND    | GND |
+| In1     | GPIO16    | Power |
+| In2     | GPIO12    | Input |
+| In3     | GPIO12    | Input |
+| In4     | GPIO12    | Input |
+
+
+###### Switch:
+
+The switch should connect the GPIO to ground if it is pressed down:
+
+* power_sw: GPIO3
+* input_sw: GPIO1
+* alarm_sw: GPIO2
+* sleep_sw: GPIO0
+
+
+You can also change this at the beginning of the code:
+```
+//Pin Taster
+const int pinTime = 3; //Pin fuer Toggle_Power und Einstellen der Uhrzeit (Lang)
+const int pinSet = 0; //Pin fuer Sleep und Zeit_Einstellung im Alarm/Time Set Mode
+const int pinAlarm = 2; //Pin fuer Alarm An/Aus und setzen der Alarmzeiten (Lang)
+const int pinInput = 1; //Pin für die Eingangswahl
+
+const int pinSleep = 9; //Pin Unbenutzt
+
+
+
+//Pin Relay
+const int outInput = 12;
+const int outPower = 16;
+```
+
+## How does it work
+
+The Clock can control 2 relays:
+
+* Power Relay: is used to turn on/off a AMP, Radio or any other device.
+* Input Relay: is to switch between two Inputs like Radio for Alarm and CD/MP3 or Aux for normal Music.
+* If an alarm is triggerd both relays are switched on.
+
+The Clock is controlled with 4 Buttons
+
+* Power-Button: turn power relay on/off 
+* Power-Button (long-press): Set clock (Day, Month, Year, Hour, Minute, Second) with Sleep-Button
+* Input-Button: turn input relay on/off
+* Alarm-Button: toggle active alarm (Alarm 1 -> Alarm 2 -> Alarm 1 and Alarm 2 -> Alarm off)
+* Alarm-Button (long-press): set alarm time (Alarm 1 Hour, Alarm 1 Minute, Alarm 2 Hour, Alarm 2 Minute) with Sleep-Button
+* Sleep-Button : set time to turn power relay off (90 Min -> 60 -> 30 -> 15 -> Off)
+
+## Issues
+
+* Alarm 2 is not working like expected. It will be triggered every hour. (Alarm 1 is ok, once a day)
+* Networkconnection is not used to update time over NTP. (not implemented yet)
+* Long-Press blocks display until release.
+
