Introduction to Arduino

Install the arduino IDE 1. https://www.arduino.cc/en/Main/Software/ 2. Select Linux 64 bit 3. Click Just Download Unzip the downloaded file as below: vbhadra@jupiter:~/Downloads$ tar -xf arduino-1.8.10-linux64.tar.xz Run the arduino IDE vbhadra@jupiter:~/Downloads$ cd arduino-1.8.10/ vbhadra@jupiter:~/Downloads/arduino-1.8.10$ ./arduino Configure 1. Tools -> Board -> Board -> Arduino/Genuino Uno Tools -> Port -> /dev/ttyACM0 Installing and uninstalling .zip user libraries in Arduino IDE Install Sketch -> Include Library -> Add .zip library Uninstall $ find ~/ -type d -iname Arduino ./Arduino $ ls -la Arduino/ drwx—— 4 vbhadra vbhadra 4096 Oct 1 11:31 libraries $ ls -la Arduino/libraries/ readme.txt xxxLPWA/ Vivek/ Remove the library folder you want to uninstall $ sudo rm -rf Arduino/libraries/xxxLPWA/ Then modify your library code, create a .zip file and install it again. Compile & verify the code Sketch -> Verify & Compile You should see “Done compiling” Upload the code Sketch -> Upload You should see “Done Uploading”. Troubleshooting 1. Issue 1: An error occurred while uploading the sketchavrdude: ser_open(): can’t open device “/dev/ttyACM0”: Permission denied -> Check if the port exist on the linux machine: ls -l /dev/ttyACM* -> Change the permission of the port as below: sudo chmod a+rw /dev/ttyACM0 2. Junk characters in serial port

void setup()
{
  Serial.begin(9600);
  Serial.write("Hello World");
}

3. Mounting the SD card into the /mnt mount -t vfat /dev/mmcsd0 /mnt
