# Alarm_Clock_ESP
This is an Alarm Clock (Radio) based on the ESP8266 in combination with a MAX7219 LED-Matrix, Relay-Board and DS3231 RTC.
Note: This Project is in heavy development at the moment.
This is an Alarm Clock (Radio) based on the ESP8266 in combination with a MAX7219 LED-Matrix, Relay-Board and DS3231 RTC.
Note: This Project is in heavy development at the moment.
## Wiring
Image how to wire the project will follow.
LED-Matrix:
| LED-Matrix | ESP8266 |
| -------- | -------- |
| VCC | Vin/5V+ |
| GND | GND |
| DIN | GPIO13 (HSPID) |
| CS | GPIO 10 |
| CLK | GPIO14 (HSPICLK) |
RTC DS3231:
| DS3231 | ESP8266 |
| -------- | -------- |
| 3,3V | 3,3V |
| GND | GND |
| SCL | GPIO5 |
| SDA | GPIO4 |
Relay-Module:
| Relay-Module | ESP8266 | Type |
| -------- | -------- | |
| VCC | Vin/5V+ | |
| 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-Button Control
* Power-Button: turn on/off Power Relay
* Power-Button (long-press): Set clock (Day, Month, Jear, Hour, Minute, Second) with Sleep-Button
* Input-Button: Swtich 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 auto-power-off (90 Mn -> 60 -> 30 -> 15 -> Off)
## Issues
* Alarm 2 is not working like expected. It will be triggered every hour.
* Network connection is not used to update time over NTP.
* Long-Press blocks display until release.
