For the moving branch, it was set a system with an HC-SR04 Ultrasonic Distance Sensor controlling a 15 kg Digital Servo Motor, through an Arduino Nano and a connective board. | For the moving branch, it was set a system with an HC-SR04 Ultrasonic Distance Sensor controlling a 15 kg Digital Servo Motor, through an Arduino Nano and a connective board. | ||

When the spectator approaches 65 cm of the branches, the servo motor starts to turn from 0 to 18 degrees, making the branches, attached to it, start to move. If the spectator approaches at a closer distance (50 cm), the servo motor turns from 0 to 40 degrees, making the branches move a little bit more. | When the spectator approaches 65 cm of the branches, the servo motor starts to turn from 0 to 18 degrees, making the branches, attached to it, start to move.

<u>2nd System:</u> | |||
The terrarium had a humidifier system inside. It was made with a Capacitive Soil Moisture Sensor connected to an Arduino Nano and a connective board. When the soil got drier (over value 400 read by that sensor, whose values are approximately this: wet is < 400, dry is > 400), a 5V Relay Module also connected to the board, activated a 5V Humidifier made with a piezoelectric. When the soil got humid again (under value 400) the humidifier stopped until the soil got dry again. The relay and humidifier received an extra supply of energy from an MB-102 3.3V/5V Power Module plugged into electricity.
