![]() While(Serial.available()=0)//WHILE serial. Serial.println(msg1) //Ask for input from user/sensor While(Serial.available())//start a loop to print in "question" string THIS PRINTS THE "msg1" String 1 time each loop then breaks Serial.println(msg1) //print out initial "string" aka msg1 Serial.begin(9600) //intialize serial com at 9600 baud Int number //assign "number" for variable value later Referencing post #7 ^^^^ if i rewrite the same code as this then it prints perfectly with no double printing: again i'm just trying to understand why his codes are not working on my unit when i'm plain as day copying his code letter for letter It enters in 1 count command and then offers no more input commandsĪs per the serial.available syntax page and now it just infinitely loops the question without waiting for an input. While(Serial.available())//WHILE serial.avail do nothing and wait I'm not a master programmer or anything but i've played with c++ for a few years before compilers could be downloaded onto phones and MSDOS and shell systems were "the up and coming thing". Why is it printing : Serial.println(question) at the beginning twice? I'm making sure i don't have a bug in my atmel328 pic. WHY? IT has nothing to do with my serial.available if my Rewritten code functioned using it. The ground wire is typically black or brown and should be connected to a ground pin on the board. The power wire is typically red, and should be connected to the 5V pin on the Arduino board. When i use his exact code letter for letter i have a double print. Circuit Servo motors have three wires: power, ground, and signal. Introduction Arduino Tutorial 17: Understanding Arduino While Loops Paul McWhorter 320K subscribers Subscribe 7.2K 145K views 3 years ago Arduino You guys can help me out over at Patreon. THEN SHOWS SAID CODE FUNCTIONING IN THE SAME VIDEO IN VIDEO.Īrduino Tutorial 18: Reading Numbers from the Serial Monitor | Technology Tutorials () THERE ARE NO ERRORS IN HIS CODE IF IT'S WORKING IN HIS VIDEO! I'VE COPIED IT LETTER FOR LETTER IN THE VIDEO! HE LITTERALLY ZOOMS IN ON THE CODE FOR YOU TO COPY IT ALONG WITH HIM. HIS EXACT CODE ON MY SYSTEM PRODUCES A DOUBLE PRINT! HIS VIDEO SHOWS HIS CODE WORKING PERFECTLY! If you’re adept with programming the Arduino and just want to learn how to use an LCD display, you can just jump right in with me on this video. have you even seen paul mcwhorter vids? he shows his published codes functioning on camera while zoomed in on the code showing letter for letter each line so you can follow along. Paul McWhorter arduino lesson 18 adrotate banner7 If you’re new to the Arduino, you probably need to go back and catch up on those lessons. Number=Serial.parseInt() //now "number" is equal to the serial INPUT lineĭigitalWrite(Rled,HIGH) //turn on the ledĭigitalWrite(Rled,LOW) //turn off the led While(Serial.available()=0)//WHILE serial.avail do nothing and wait 8 9 The sensor readings during the while loop define the minimum and maximum of 10 11 expected values from the photoresistor. 6 7 While the pushbutton is pressed, the sketch runs the calibration routine. Serial.println(question) //Ask for input from user/sensor 1 2 3 Conditionals - while statement 4 5 This example demonstrates the use of while () statements. Void loop() //Ask first, wait, then read to get data from serial com LESSON 1: Simple Introduction to the Arduino LESSON 2: Simple Arduino Breadboard Tutorial LESSON 3 - Arduino For Loops and LED Circuit LESSON 4: Printing. PinMode(Rled,OUTPUT) //assing "Rled" D6 pin as an OUTPUT Serial.begin(115200) //intialize serial com at 115200baud Int number //assign "random1" for variable value later Cycling is a great way to spend time outdoors while simultaneously getting exercise and even as a mode of efficient transportation. ![]() rewriting it as this solved all my issues, BUT WHY DID I HAVE TO WRITE IT DIFFERENT THAN WHAT I WAS SHOWN ON THE LESSON? Shouldn't his code of worked no issues on my unit? Celebrate World Bicycle Day with these Arduino-powered bike projects. 00001%ĪGAIN THE ISSUE IS WHY FOLLOWING HIS EXACT CODE DID NOT REPRODUCE THE SAME RESULTS HE SHOWED? since my first post wasn't clear enough i'm guessing. In the second one, there is a long loop (which could last even longer) in the loop() function.That still doesn't answer why my unit isn't doing what his is so it doesn't solve my issue by even. Here, I make sure not to "lock" the loop() function Using a loop to set integer values for each colour of the RGB LED. I’ve played with this setup for a while and it worked out really well, of course I wasn’t pushing for 16×106 colors but it is fun. In the following one, I make sure not to "lock" the loop() function : const int PIN_LED = 2 Books You Should Read: Basic Electronics Hackaday. Here are two ways to do it with the Arduino. To illustrate my question, let's say I want to make a LED blink a thousand times. ![]() I'm wondering if there are any reasons not to loop inside the loop() function.
