Day 4- Programming Two LEDS

Programming Two LED'S

  For this challenge, we had to make the green LED and the red LED go on simultaneously after each other.   Then we had to make them go on for 2 seconds, by using the delay feature when we programmed the arduino. Following that we had to make the green light blink 3 times and the red one blink once. One problem we encountered was that originally we programmed the red one to blink 3 times and the green one blink once. SO it was opposite!

Day 3 continued- programming the external LED

Programming the external LED:

    Continuing from the last challenge where we had to make the LED on breadboard light up, for this challenge we had to make the LED blink.   One problem we encountered was when we had to change the code so that the LED would go on for a second then off for a second , then on /off for 5. 

Day 3- Keep a Light On for me

Keep a Light on for Me - Day 3 

 
Today we started using the breadboard to build
our first circuit.  We used one black and red jumper
 wire and a transistor to make the red LED light blink.
(video above of LED blinking)

Modify a Blink- Day 1 Continued

Modify a Blink - Day 2 

                                              

 Today we continued to modify the light 13 on the board of the arduino.  With the second challenge,  we had to modify the code so that it would keep the light on forever. To do this, we removed the last 3 lines of code on the loop function of challenge 1.  We then had to use the delay function (The delay(1000) command delays the computer for 1000 milliseconds) we then modified the code so that the light would stay on for 10 seconds and go off for one and loop.

Day 1 - Blink a Light

   Blink a Light - Day 1

      Today we have just received the Arduino and we proceeded to make the board near number 13 blink on and off.  The code we wrote for the arduino made the yellow light on board blink on and off for an endless loop.
