About a month ago I joined the amazing community of Thingiverse and started uploading my first designs made on Blender.

One of the first projects is to control automatically the curtain blinds to ensure we don’t have to get up to turn them manually. Actually it’s just a great excuse to learn more about arduino and stepper motor controlling.

This is the basic schema to control light detection:

Then I just connected some leds to the digital output:


int ledPinMin = 2;
void setup() {
Serial.begin(9600);
pinMode(ledPinMin, OUTPUT); // declare the ledPin as an OUTPUT
pinMode(ledPinMin+1, OUTPUT);
pinMode(ledPinMin+2, OUTPUT);
pinMode(ledPinMin+3, OUTPUT);
pinMode(ledPinMin+4, OUTPUT);
pinMode(ledPinMin+5, OUTPUT);
}
void loop() {
int sensorValue = analogRead(A5);
int ledPin = sensorValue/50 +2;
digitalWrite(ledPin, 1);
delay(sensorValue);
digitalWrite(ledPin, LOW);
delay(100);
}


I really like the projects like arduino and the power that brings 3D printing to the table. It’s a great combination. Anything can be done you just need to have an idea and be creative enough to make it happen.
