![]() In my world that would be a Digital Analog Converter, but I'm sure that not what you mean. (still looking for a rich sponsor who wants to pay me to do this website as a day time job hahah )įirst off, since it confuses me. Sorry for the late response - thing have been a little crazy here the past few days. I attached two files, one has setup and loop and the other have the functions called. I'm stuck with only my eyes, fingers and what's left of my neurones and it doesn't seems to be enough Although I'm a beginner with Arduino sketches so I might miss something quite easy. I wanted to debug using the serial console connection but since I actually don't use an Arduino but rather an Adafruit Pro Trinket and it doesn't have the serial-to-USB chip. Then when I connect the 'RaspberryPi Connected' wire it breaks my switch/case and each case seems to be running at the same time. Phase 1 &2 works perfectly fine, no glitch whatsoever. ![]() From there I want to animate another time with the sine waveform fade in/out again except this time it wont go down to 0% but instead a 'brightness' value.Ĥth phase: Here I used a fade in/out without the loop to keep the same brightness all the time.Īll seemed goos to me but I have a weird behaviour if I run the program. For those who wonders how, here is my source and the reason why I used radians.Ģnd phase: I used twinkle effect to indicate that the RaspberryPi is starting and then connects to my NAS serverģrd phase: Once connection is established, the RaspberryPi update an output to inform the Arduino that the connection is OK. I replaced the ramp with a sine waveform. I want to cycle through phases:ġst phase: I used fade in/out effect to light up from 0% to 100% (I actually don't use 100% because it's making too much light) and then back to 0%. Bookmarked! I believe this helps a lot of people getting started with these and the time and patience you took to right it makes it all very educational! Unfortunately for me I suck a lot at VHDL and during my struggle with it I came across your website and more precisely FastLEDs effects article. In the first place I wanted to use basic LEDs with PWM to modify their brightness in VHDL. I am currently working on DAC design since last year. So I answered my post and probably trigger an anti-bot detection which got rid of all the explanations I had written. The program continuously runs this pattern, with a 1-second delay between each row.I posted on the effects article saying I would create a topic but there was something wrong, I couldn't. The pattern is printed on the serial monitor, with each row containing an increasing number of * characters. This code uses mixed nested loops to generate a right-angled triangle star pattern with five rows. In Arduino, the loop function runs continuously after the setup function, but since there is no code inside the loop function, it remains idle and does nothing. Void loop() : The loop function is empty and does not contain any code. Serial.println() : After printing the * characters for a row and adding the delay, Serial.println() is used to move the cursor to the following line on the serial monitor, ensuring that each row is printed on a new line. This delay lets you observe the pattern more clearly on the serial monitor. This nested while loop ensures that the number of * characters printed in each row correspond to the value of currentRow, resulting in a right-angled triangle pattern.ĭelay: After printing each row, a delay(1000) is added, creating a 1-second pause before printing the next row. In each iteration of the while loop, it prints a * character using Serial.print("*") and decrements the numStars variable by one using numStars. It runs from currentRow = 1 to currentRow 0. The outer for loop is used to control the number of rows in the pattern. Nested loop: The code utilizes a mixed nested loop structure to create the star pattern. ![]() Int currentRow = 1 : This variable currentRow is initialized to 1, representing the current row of the star pattern being processed. Int numRows = 5 : This variable numRows is set to 5, indicating that we want to create a star pattern with five rows. Variable initialization: Inside the setup function, two integer variables are declared and initialized: It initializes the serial communication at a baud rate of 9600 bps (bits per second) using Serial.begin(9600). Void setup() : This is the setup function, which runs once when the Arduino starts. This Arduino code uses mixed nested loops to create a star pattern and print it on the serial monitor.
