SmartMirror
Description
SmartMirror is a DIY project. Basically it is an LED-Matrix of 64x16 placed behind a translucent mirror. It is powered by a NodeMCU chip, so it has WiFi capabilities. It can show the time in some special decimal form (where the day has 10 hours, a hour 100 minutes and a minute 100 seconds) but a normal 24-hour format is also possible. A DHT11 temperature and humidity sensor provides ambient values. Through implementation of a simple HTTP server, the mirror can react to GET requests. It gathers the current time via NTP (thus it needs to be connected to the Internet).
You can find the code on my Github repository "smartmirror".
Required libraries:
- Ultrathin_LED_Matrix by Seeed-Studio
- DHTNEW by RobTillaart
- Time by PaulStoffregen
- Timezone by JChristensen
GET request modes
| /clock10 | Shows the clock in decimal mode. |
| /clock24 | Shows the clock in 24-hour format. |
| /temperature | Returns the temperature. |
| /humidity | Returns the humidity. |
| /disable | Shuts off the display (but continues to respond to requests). |
| /enable | Turns the display on. |
| /text? | Shows text on the screen. style=[ marquee | rightbound | leftbound | center ], default is marquee In case of marquee: direction=[ right | left ], default is left; speed=THE HIGHER, THE SLOWER |
