Recently I have been trying to get a arduino to control the brightness of an 12v rgb strip using the serial monitor. The project that I'm doing this needs the colors: violet, blue, green, yellow, orange, and red. I cant figure out the code so if any one can help …

I've been trying to have a button (Arduino) change the fill color of an ellipse in Processing 3. I thought an if statement like `if(button == 0){ if(fillValue == rgb){ fill(0,0,0);}`or something more or less. So if some one has the awnser please help.

Recently I have been assigned to create a serial. print code for a class. I have the code almost done but I do not know how to get my "X" and "Y" variables seperate(in colums like if; y=-2x+1). Also I was woundering how to insert a table(or code in a …

I'm using python to try and talk to my Arduino with pyserial. The code should wait for an input from COM5, (the arduino), and then sends a 1 and waits for the response. import serial connected = False ser = serial.serial("COM5", 9600) while not connected: serin = ser.read() connected = …

I am trying to send some strings on my android device using bluetooth to my arduino so I am wondering if my logic is correct for my code. The part I am stuck on how to implement if all arguements are OK then it should send String temp = "t"; …

Hey everyone! Hosftra comp sci grad here who got into IT for my career. I think I remember Dani from college! So happy to finally register for this awesome community! I'd like to get back into programming a tiny bit with arduino and the Raspberry Pi. See ya around the …

I know there are plenty of other places to get info or code snippets for **microcontroller programming** (especially **arduino**). Out of all the boards/sites I visit, I like the **DaniWeb** format the most. I was wondering if a **microcontroller** or **arduino** section could have a home here. Or would that …

I have got very weird problem with a int variable. There is a code: #include <EEPROM.h> #define dht_dpin 14 byte bGlobalErr; byte dht_dat[4]; int a; void setup(){ pinMode(13, OUTPUT); a = 0; InitDHT(); Serial.begin(9600); delay(300); Serial.println("Humidity and temperature\n\n"); delay(700); } //end "setup()" void loop() { digitalWrite(13, HIGH); delay(300); digitalWrite(13, LOW); …

im using this code to send strings to serial port but this is very slow,the other end of communciation arduino board is not able to get those strings at realtime,how can i fasten this communication? there is no problem in arduino board or arduino code,it works fine for its sample …

Hi, I've been trying to send a long integer from an Arduino to my C++ program via the serial port. There seems to be many examples of this when i search, but I've not had much luck except for one example. This example seems to work, but not when I …

Hello, I need to implement a simple project: create a basic web-site to read online stream from my web-camera using its IP address. BUT I´d like to use my Arduino microcontroller and WiFly shield without using a laptop. Could please someone give an advise - links to related tutorials or …

when creating electronics projects, do you prefer parallax or arduino? why?

Hey Guys, I am pretty new to C#. Below is some code that i am using to send data serially to an Arduino controller. It just has some push buttons which move the wheels/motors etc of an RC car i have. I have put some text boxes onto the form …
