Arduino project for temperature control.
This is my Plant Bot! I'm very proud of it. It keeps accurate time with a RTC module, measures temperature and humidity with a DHT11. It has a 4 relay board that can handle up to 30v DC 120v AC and 10A. The screen is a 1602 LCD module, and the Arduino is an UNO R3. It's pretty easy to get into making little Arduino projects, there are so many examples and resources online. 90% of the code that actually runs the sensors I found and adapted to my needs. The hardest part was just making a unit that can be controlled as a standalone project. Here is the source code and libraries I used.
