Controlling arduino using serial openwrt

Controlling arduino using serial openwrt

1. Create sketch

// include the library code:
#include

// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(7, 6, 5, 4, 3, 2);

void setup() {
  // set up the LCD's number of columns and rows:
  lcd.begin(16, 2);
  // initialize the serial communications:
  Serial.begin(9600);
}

void loop() {
  // when characters arrive over the serial port...
  if (Serial.available()) {
    // wait a bit for the entire message to arrive
    delay(100);
    // clear the screen
    lcd.clear();
    // read all the available characters
    while (Serial.available() > 0) {
      // display each character to the LCD
      lcd.write(Serial.read());
    }
  }
}

2. Upload the sketch
3. For testing the arduino ,open serial monitor, and type something.

Exroot OpenWRT on TPLink MR3020

Langkah langkah exroot

1. siapkan usb flashdisk, buat 2 partisi, partisi 1 buat swap file besarnya 500M saja,
   partisi 2 jenisnya ext4 besarnya sisa dari partisi yg ada.
2. siapkan MR3020 dengan firmware barrier breaker dan sudah tersetting konek ke internet.
3. masuk ssh ke ip router
4. ketik perintah update
opkg update
5. install driver usb storage
opkg install block-mount kmod-usb-storage kmod-fs-ext4

kalau ada error
kmod: failed to insert /lib/modules/3.10.49/ext4.ko
biarin aja

6. reboot
7. cek apakah usbnya sudah terdeteksi

8. install paket untuk exroot
opkg install block-mount kmod-fs-ext4 kmod-usb-storage kmod-usb-ohci

9. cek partisi yg ada di flash disk
block info

yg sda1 --> swap  yg sda2 --> ext4

10. copy file system ke sda2

langkah langkahnya

mkdir -p /mnt/sda2
mount /dev/sda2 /mnt/sda2
mkdir -p /tmp/cproot

Blocking Porn on Network using Squid

Here the step blocking porn site using squid


I assumed that the squid proxy run well,

the step :
Open the squid.conf

add the script :





and add the script :

http_access deny porn on the top of  http_access allow manager localhost

 create the file and name it wordblock.txt in /etc/squid folder



after that pres Ctrl+X than save


change the owner of that file

#chown proxy:proxy /etc/squid/wordblock.txt

make permittion to allow to execute that file

#chmod +x /etc/squid/wordblock.txt

after that restrat your squid
