Actually, this also comes with temperature control (fan and led/light bulb as output).
I guess, or whatever it called.
| Block | Component |
|---|---|
| Activator | +6V adaptor |
| Input | RTC DS3231, Ultrasonic, DHT11, and Blynk. |
| Process | Microcontroller and Relay |
| Output | Servo, LED, Fan, Buzzer, and Blynk. |
- Microcontroller is any arduino-like such as NodeMCU ESP8266 (the one used on this project), Wemos, or anything that could use arduino IDE and ESP8266 as Wi-FI module.
- Relay is optional and needed if LED is replace with light bulb and bigger fan.
- Im using +6V adaptor in this project, + connected to Vin and - Connected to GND on microcontroller.

To adjust RTC time according to your local (PC) time, uncomment this code: rtc.adjust(DateTime(F(__DATE__),F(__TIME__))); and upload it to your microcontroller.
Since the code is in setup() function, it will executed everytime the microcontroller switched on and the time will be reset back to when it first adjusted.
To overcome this, you need to upload your code twice, first with rtc.adjust(DateTime(F(__DATE__),F(__TIME__)));, and second without it. The time will not be adjusted nor stopped when you upload the second code as long the RTC has it's battery.
PS: im not using PCB board, i use jumper cable. Please double check the line.
