I learned about making circuits, using resistors in those circuits, and the basics of writing/ fixing code for making an LED blink every second.

 

When making the circuits themselves, I learned how to make sure that the circuit is fully connected from both positive and negative leads along with a ground. I also learned to use a resistor in the middle of a circuit in order to make sure the LED it is connected to doesn’t burn out. Finally we used code to program an arduino to make an LED blink every other second. Part of the code wasn’t working perfectly, so we had to modify it to work for our purposes. Here is the code:

//Sets Red to digital pin 8 and Green to digital pin 7

#define Red 8

#define Green 7

 

void setup()

{

//Initializes pin 8 and 7 as outputs

 pinMode(Red,OUTPUT);

 pinMode(Green,OUTPUT);

}

 

void loop()

{

//Blinking

 digitalWrite(Red,HIGH); //Red on

 digitalWrite(Green,LOW); //Green off

 delay(500); //Wait half a second

 digitalWrite(Red,LOW); //Red off

 digitalWrite(Green,HIGH); //Green on

 delay(500); //Wait half a second

}
