09. Exercise from (08_Temp_Motion)

The connections for our ESP on breadboard:

ESP GPIO	Port	What
13	1	LED (leg with resistor)
12	6	Temperature sensor Data pin
14	7	Motion sensor Out pin
4	4	IN1 from 2-Relay Module
5	5	IN2 from 2-Relay Module

We added 2 new classes:

• DHT22FeatureController
• MotionFeatureController

Upon program start:
