Hello, I am very new to Arduino. I am wanting to build a small system that will monitor the temperature and turn on a heater when the temperature drops below a specific reading, then turn it off when it the environment gets to another temperature. I want to use the mega 2560 microcontroller. I'm not sure what other components that I will need. Please reply with specifics. Or reply with good websites that I could visit to learn more about this type of project.
I am not looking for someone to do it for me. I am looking for help identifying the parts that I need, like a BOM.
These are the parts that I know I will need.
*Black Cased MEGA 2560 R3 Board ATmega2560-16AU CH340G
*DHT11 Temperature and Relative Humidity Sensor
*Yellow Serial IIC/I2C/TWI 2004 204 20X4 Character LCD Module Display
*Iot Relay - Enclosed High-power Power Relay for Arduino
I think I need this also:
Sensor Shield Digital Analog Module Servo Motor for Arduino UNO R3 MEGA V5 SV2
Also, other than ebay and amazon, what are some good sources in the US for these parts?
Any help would be appreciated.
