understand in more detail ou must read this Arduino introduction article. as you read above the same instruction applicable for the rest of all. it means on which pin what will be the mode. here is a word pinMode which carr two words pin & Mode. the whole line meaning is pin number 1 will act as an output pin. ( according to this statement the LED_1 variable which is assigned above on pin 1 will work as an output. there we initiate the program data as given as below for example to set and output and input pins, setting up of baud rate, initiate another peripheral like Bluetooth, wifi, and much more.Īnd there are two curly braces open and close we have to write the statement of function inside in these braces. Void setup is the function to set the initial for the main functions. The second step is to make a void function as given below:. These functions don't exist yet, but don't worry, we'll get to them.In the above line, we are assigning and variable LED_1 to the 1 pins of Arduino, variable LED_2 to the 2 pins of Arduino. We will also call a couple of functions with a 5 second delay in between. In your setup function we will set our Arduino pins to output. You will also need to create a variable to control how fast the fading will happen. We will only be using the main brightness variable for turning the LEDs off, so set it to the maximum brightness value of 255 here. Create an overall brightness variable, along with a variable for each individual color's brightness. Make sure your MOSFETs are logic level and not standard.īegin by defining which pins will be used to control the MOSFETs. When using microcontrollers, it is important to use logic level components in order to ensure things work the way you want them to. By passing each of the LED strip's colors through the MOSFET, you can control the brightness of each individual color on the LED strip. By sending pulse width modulation ( PWM) signals to the gate leg, it's possible to control how much power passes between the drain and source legs. One of the simpler ways to do this is to use a MOSFET. Whenever you are controlling something which is higher voltage than your microcontroller, you need something in between to stop your board getting fried.
