My first project with Arduino and coding was using LEDs in a creative way. I decided to use morse code as that was a way to communicate to a person with only blinking lights . I went basic and used 5 LED lights to spell out HELLO, in morse code. This project helped , understand the possibility that is possible with coding and engineering.
RGB LED
To advance more into manipulating a LED light, I was able to use an RGB LED light to make what ever color would like through the power of code.
Without the availability to a photo-resister I substituted a (WORD) for it. This senses the force applied to control an aspect of the LED that is set in code. I set mine to control the LED to blink and depending on how much force applied, the speed of the blink.
Digital Input/Analog Input
For this project I used a button and a dial. The button I set to control the speed the the LED light blinks. The more you press it the faster it gets until it is a solid light. Te dial comes into play here as it was set to control the brightness of the LED.
