# Alarm_Clock
|
|
|
|
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 | GPIO8 | Power |
|
|
| In2 | GPIO7 | Input |
|
|
| In3 | GPIO7 | Input |
|
|
| In4 | GPIO7 | Input |
|
|
|
|
|
|
###### Switch:
|
|
|
|
The switch should connect the GPIO to ground if it is pressed down:
|
|
|
|
* power_sw: GPIO2
|
|
* input_sw: GPIO5
|
|
* alarm_sw: GPIO4
|
|
* sleep_sw: GPIO3
|
|
|
|
|
|
You can also change this at the beginning of the code:
|
|
```
|
|
//Pin Taster
|
|
const int pinTime = 2; //Pin fuer Toggle_Power und Einstellen der Uhrzeit (Lang)
|
|
const int pinSet = 3; //Pin fuer Sleep und Zeit_Einstellung im Alarm/Time Set Mode
|
|
const int pinAlarm = 4; //Pin fuer Alarm An/Aus und setzen der Alarmzeiten (Lang)
|
|
const int pinInput = 5; //Pin für die Eingangswahl
|
|
const int pinSleep = 6; //Pin Unbenutzt
|
|
//Pin Relay
|
|
const int outInput = 7;
|
|
const int outPower = 8;
|
|
|
|
```
|
|
|
|
## 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
|
|
|
|
* Long-Press blocks display until release.
