Board: Arduino UNO

Aim: do something by alarm scheduler

Current version features: a. show temperature b. electric ball Valve control (manual and alarm) c. turn on Relay (manual and alarm) Remember settings in EEPROM

Quick start

1. install platformio
2. change COM port in platformio.ini file here
3. run init.sh to download external libraries
4. download NewLiquidCrystal library manual to ./library folder
5. run run.sh to compile and upload sketch to arduino
6. if #define LOGGING, you can see debug info reading COM port. run serial.sh

Electric ball Valve control

Valve has 3 pins(GND, open, close) by default 12V. But the power of Arduino is 5V. I invert power by solder and got PWR, open, close. Now I can use Transistor to move it. Arduino pins open Transistors and got GND on open or close pin.

Algorith:

1. open pin turn on for 5 seconds (motor works).
2. open pin turn off. Valve is open.
3. enjoy
4. closing pin turn on for 5 seconds (motor works).
5. closing pin turn off. Valse is close.

Additional libraries

Hardware

1. NewliquidCrystal - LCD 16x2 i2c display driver
2. OneWire - 1-wire device support
3. Arduino-Temperature-Control-Library - Dallas DS18B20 temperature sensor driver
4. DS1307RTC - real time clock driver

• read/write EEPROM

Software

1. ArduinoMultiDesktop - easy 2 buttons change screen library
2. ArduinoMenu - great library for print menu settings
3. TimeAlarms - alarm library
4. Time - needs to alarm library for time functions
