Code blocks not respecting code

So, I got some feedback that my 'ible has some errors in it (which is somewhat expected :D )  I went to the instructable, to do some editing and noticed that the problems are likely coming from and tags that are in the code blocks. I tried to remove them, but they come back when I save.  I noticed this happens in *all* my code blocks.  Changing the format of text in code blocks makes Instructables unacceptable as a way to share code. Considering the amount of code for many projects on this site, this potentially breaks many of them, or at the very least makes it harder for others to copy the code for their projects.   Please make tags repect all formatting within!  Thanks, JR

Arduino code Answered

Hello, I have been trying to make code for my arduino. I would like code to tell my arduino to receive a servo signal from my rc receiver, then detect whether the signal is telling the esc to move forwards or backwards. If the signal is forwards, it simply relays that code to the ESC. If the signal tells the ESC to go backwards, then it sends a signal to go forwards at the speed it would have gone in reverse, while sending out a power source to power a relay. Chowmix12 came up with some code that may help and I put  "//" before all of the code that was not needed for his application to work. Also, this link may be helpful for multitasking.  #include Servo ThrottleServo; //int PWMpin = 2; // connect RC receiver here. //int ServoVal; //int RCinput; void setup() { //Serial.begin(9600); //ThrottleServo.attach(9); // attaches the servo on pin 9 to the servo object //ThrottleServo.write(97); // go to nuetral pinMode(13, OUTPUT); } void loop() { //RCinput = pulseIn(PWMpin, HIGH, 20000); //ServoVal = map(RCinput, 520, 2370, 0, 180); //if(RCinput== 0) { // Signal timed out! digitalWrite(13, HIGH); // ALERT! ThrottleServo.write(97); // Go to neutral throttle position } //else{ // digitalWrite(13, LOW); // everything's fine. // ThrottleServo.write(ServoVal); // Repeat the data to the truck's ESC // Serial.print(" PulseMicros "); // This part is used to debug the values for calibration // Serial.print(RCinput); //Serial.print(" ServoRead "); // Serial.println(ServoVal); // } //} My program so far is as follows. /* created 2005 by David A.

Learn Morse Code

I saw a number of instructables on how to build various kinds of telegraphs, and one including a mapping of characters to either left or right, according to the number of dot's and dashes required to represent it. however, i am missing an instructable about how to LEARN such code. so i've been thinking. it's what i do some times. and i came up with this idea. i am searching for a software that would present you a blank screen. then a letter should appear on the screen, and a sound of the corresponding morse code should be heard. a couple of times. then the same with another letter. next, random letters should show up. the newer they are to the viewer, the often they should be shown and played. after some time, words should appear letter by letter, while playing them. and so on. can anybody help me finding such a piece of software? can anybody make such software?

Arduino code help? Answered

I'm really new to the arduino and I'm struggling to get this code working. I'm trying to have a servo continuously go back and forth until I change its state, which result on the servo to stop at its current position. However, it gets stuck on that for loop and i can't change its state. I assume this is caused by the delay, but I am not sure how to make it so it works without delays, unless there is another way.My code is right here: {edited} const int Button = 2; //This is interrupt 0 int Pos; const int button2=14; volatile int sweep = HIGH; //Our state variable, initialise so we always sweep #include Servo servo1; int buttoncount=1; int lastbuttonstate=0; const int led_1=7; void setup() { servo1.attach(10); pinMode(Button, INPUT); pinMode(button2,INPUT); pinMode(led_1,OUTPUT); Serial.begin(9600); attachInterrupt(0, Isweep, CHANGE); } void loop() { Serial.println(buttoncount); switch(buttoncount){ case 1: servo1.write(0); digitalWrite(led_1, LOW); break; case 2:     Pos=0; while (Pos<180 & sweep==true) {servo1.write (Pos); Pos++; delay(10); } while (Pos>0 & sweep==true) {servo1.write(Pos); Pos--; delay(10); } break; case 3: digitalWrite(led_1,HIGH); break; default: Serial.println("error"); } //both these whiles will terminate and not do anything if sweep is true. } void Isweep() //Interrupt routine { int buttonstate=digitalRead(Button); if (buttonstate !=lastbuttonstate){    if (buttonstate==HIGH){      buttoncount++;    } } lastbuttonstate=buttonstate; if (buttoncount==4){    buttoncount=1;   } sweep = !sweep; while (digitalRead(Button)==true); //change state only once when button is pressed }

Arduino Code Help

Hello! for(int i=0; i<5; ++i) I know this little bit of code is probably very simple but for some reason I'm having a hard time understanding it. It seems like 'i' would be reset to 0 ever time it was done with the statement in brackets. How can you put multiple test statements inside of a if statement? When I try to add another one  like this for(int i=0; i<10; i>3; ++i), it doesn't work. Why can't I add another one? Why is it ++i? I thought it was supposed to be i++. Could someone please explain it? Thanks! for(int i=0; i<5; ++i)  {    repeat something in here    delay(100);  }

Arduino code help

To the Instructables members,       I'm trying to write a program that uses a pushbutton (momentary) to turn on and off LEDs.  I have two LEDs and one button.  Basically, I want to be able to push the button to switch LEDs.  One push - one LED turns on - another push - the second LED turns on - another push - the first LED turns on - and so on.  Anyone know how to do that?  I'm sure there's a simple solution that I've missed.  Any aid would be awesome.

Arduino code help

Hey guys, So Im by no means good at coding. I can work with electronics, but the coding part of arduino is beyond me. I normally work with libraries that others have already created.  Im just wondering, is there anyway someone could help me write an arduino sketch for a personal project? Im using a arduino nano and a strip of 22 ws2812b led strips seen in my last instructable; I worked around the neopixal library until I got the rainbow cycle effect seen here (Not my video) Im just wondering if its possible to make the rainbow cycle code run between 3 different colors such as red green and yellow or red white and blue. here is my current code #include #ifdef __AVR__   #include #endif #define PIN 6 // Parameter 1 = number of pixels in strip // Parameter 2 = Arduino pin number (most are valid) // Parameter 3 = pixel type flags, add together as needed: //   NEO_KHZ800  800 KHz bitstream (most NeoPixel products w/WS2812 LEDs) //   NEO_KHZ400  400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers) //   NEO_GRB     Pixels are wired for GRB bitstream (most NeoPixel products) //   NEO_RGB     Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2) //   NEO_RGBW    Pixels are wired for RGBW bitstream (NeoPixel RGBW products) Adafruit_NeoPixel strip = Adafruit_NeoPixel(PUT THE NUMBER OF LED's HERE, PIN, NEO_GRB + NEO_KHZ800); // IMPORTANT: To reduce NeoPixel burnout risk, add 1000 uF capacitor across // pixel power leads, add 300 - 500 Ohm resistor on first pixel's data input // and minimize distance between Arduino and first pixel.  Avoid connecting // on a live circuit...if you must, connect GND first. void setup() {   strip.begin();; // Initialize all pixels to 'off'   // Some example procedures showing how to display to the pixels: } void loop() {   rainbowCycle(20); } // Slightly different, this makes the rainbow equally distributed throughout void rainbowCycle(uint8_t wait) {   uint16_t i, j;   for(j=0; j<256*5; j++) { // 5 cycles of all colors on wheel     for(i=0; i< strip.numPixels(); i++) {       strip.setPixelColor(i, Wheel(((i * 256 / strip.numPixels()) + j) & 255));     };     delay(wait);   } } // Input a value 0 to 255 to get a color value. // The colours are a transition r - g - b - back to r. uint32_t Wheel(byte WheelPos) {   WheelPos = 255 - WheelPos;   if(WheelPos < 85) {     return strip.Color(255 - WheelPos * 3, 0, WheelPos * 3);   }   if(WheelPos < 170) {     WheelPos -= 85;     return strip.Color(0, WheelPos * 3, 255 - WheelPos * 3);   }   WheelPos -= 170;   return strip.Color(WheelPos * 3, 255 - WheelPos * 3, 0); } Please let me know or if you can help ill take any advice Thanks!

Arduino dimmer code

I am creating a 6 channel light dimmer system using an arduino duemilanove. I want to control it using push buttons to  dim and brighten. I want to setup 6 buttons to corresponding to the 6 channels. Then I want an up, down, and on/off button. When you hold down a channel button, it activates to up and down button to control that channel. I want the on/off button to turn all channels to full brightness or completely off. I am basing the dimming part of the circuit off of this instructable: Anyway, I have ordered an arduino but want someone to check out my code before I build this.

if/else Arduino code

So I need a little help building some if/else statements. I went to the Arduino website but there wasn't a whole lot of information there. I need some help with reading analog input and reacting to them. I'm not totally sure how to use the == either, I know it means do something if one thing is equal to, but. . . Also, with the if/else, I need some help with using >= => (i think??) as well as true and false. I also think you can like use two different if statements and only one else. Could I get a little assistance from you guys!? Here's an example: if(analog_in (is less than) 5) {  do something here  } else {  do another thing here } Here's another example: if(analog_in (is equal to, I think ==) 5); {   analogWrite(LED, 100); } if(analog_in (is greater than) 5); { analogWrite(LED, 255); } if(analog_in (is less than 3, but greater than 1); {  analogWrite(LED, 50); } and if none of that is true, then do this else {  digitalWrite(LED, LOW); } So you can see I need some help!  Thanks!
