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.

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 }

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!

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!

Windows COA code Answered

Hello. My desktop computer`s hard drive corrupted a while ago due to a power surge and rendered it unusable. After consulting a computer savy friend he said I would need a new hard drive. I have finally began to repair it, I have bought a new hardrive and was wondering can I use my original COA code from windows XP to clean install Windows 7? The reason I ask is that windows 7 is very expensive from new, however you can get the offical disks with supposedly working COA codes for half the price on ebay. They say they are from de-activated computers however I am worried I will buy one and the code will already be in use or invalid. So as a backup would my original code work or would it say it is still in use? (P.s I am not interested in getting windows 8 or 8.1, I cannot afford it) Thankyou :)

Interference of codes problem

I want to ask for some help from you regarding of my final year project. I'm doing a simple SMART HOME project by using Arduino wemos. While compiling the function of the smart home, i've encountered some problem to compile it. Actually this is my first time using arduino and i don't really understand about the arduino ide syntax. Actually, there is no error in my coding. Basically, there are 5 functions that I want to put in that smart home. First, to control the lights,curtains and fans using ON/OFF Button, and security system only by using TSOP and IR, and lastly controlling the roof for the clothesline. So, I've problem with controlling the roof for the clothesline. The roof for the clothesline works when the rain sensor detects water/rain and it actually functioning when I do it separately. But, when I compile the code with the other functions, the roof is actually functioned, but it works only if I switch ON/OFF the lights/fans/curtains. So, here I attached the source code of my project with four functions, which are for the lights, fans, curtains and roof.

Help with Arduino Coding

Hello. I have recently been interested in coding Arduino and the USAF lets me to launchpads to setup remote cameras that are sound activated for a rocket launch. I was working on designing an Arduino connected to one of the cheap sound detector modules on eBay. The camera would be triggered by a short circuit on the digital end, with the sound module on the analog end. The camera is activated by a short circuit on the shutter release, so I though I would have + going into the camera when sound is activated with the other cables on ground. I just needed someone to check over my coding, as I am debating whether or not to buy an Arduino. No errors appeared on the computer, so I don't know if it will work fine or not                                                                                                                                                                                                                void setup() {}   //Just there as placeholder: void loop()    //To repeat a function of detecting sound: {const int SoundDetectorPin = A2;  //Sound Detector Module located at Analog pin 2:   const int CameraTriggerOutput = 3;  //Dual Trigger Output is located at Digital pin 3: //Following is If functions: if (analogRead(SoundDetectorPin) == LOW) //When power is read, if it is LOW, the trigger detected sound:      digitalWrite(CameraTriggerOutput, HIGH); //Pin 3 is given positive voltage: else {  //If opposite happens:     digitalWrite(CameraTriggerOutput, LOW); //When power is read, if it is HIGH, the trigger is detected nothing and no command is excecuted:    } }

Arduino code help

Hey guys first post.  I need some help with some code Im working on. What I want to do is have a pot controlled timer that moves a servo after a time dictated by the pot. The scale of delays I want is 0-3 minutes.  I eventually want to program an Attiny85 chip to do this. For now Im substituting a led in for the servo. Im a newbie with Arduino so any help with this simple project would be greatly appreciated. This is my code:  int sensorPin = 0;    // select the input pin for the potentiometer int ledPin = 13;      // select the pin for the LED int sensorValue = 0;  // variable to store the value coming from the sensor void setup() {     pinMode(ledPin, OUTPUT);    int val = analogRead(0);     val = map(val, 0, 1023, 0, 30000);       digitalWrite(ledPin, HIGH);       delay(val); delay(val); delay(val); delay(val); delay(val); delay(val);           digitalWrite(ledPin, LOW);                         } void loop() {                   }
