# Blynk controllable relay
|
||
|
|
This usermod allows controlling a relay state from the user variables. It also allows the user variables to be set over Blynk.
|
||
|
|
|
||
|
|
Optionally, the servo can have a reset timer to go back to it's default state after an interval. This interval is set through userVar1.
|
||
|
|
|
||
|
|
## Instalation
|
||
|
|
|
||
|
|
Replace the WLED06_usermod.ino file in Aircoookies WLED folder with the one here.
|
||
|
|
|
||
|
|
## Customizations
|
||
|
|
|
||
|
|
Update the following parameters in WLED06_usermod.ino to configure the mod's behavior:
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
//Which pin is the relay connected to
|
||
|
|
#define RELAY_PIN 5
|
||
|
|
//Which pin state should the relay default to
|
||
|
|
#define RELAY_PIN_DEFAULT LOW
|
||
|
|
//If >0 The controller returns to RELAY_PIN_DEFAULT after this time in milliseconds
|
||
|
|
#define RELAY_PIN_TIMER_DEFAULT 3000
|
||
|
|
|
||
|
|
//Blynk virtual pin for controlling relay
|
||
|
|
#define BLYNK_USER_VAR0_PIN V9
|
||
|
|
//Blynk virtual pin for controlling relay timer
|
||
|
|
#define BLYNK_USER_VAR1_PIN V10
|
||
|
|
//Number of milliseconds between updating blynk
|
||
|
|
#define BLYNK_RELAY_UPDATE_INTERVAL 5000
|
||
|
|
```
