Project Euler

Project Euler is a website that contains math questions which can solve with programming. All of these problems answers can find in one minute or less. There are many programmers all around the world that try to solve problems. I lost my interest on the website but nowadays, again, I try to solve problems.

Here is the link of website : https://projecteuler.net

And it’s my profile.

 

Have a nice day.

Raspberry Pi Starting With Script

Say that we have a folder name ~/Proj

Before all else we should be root.

sudo su

nano etc/rc.local

After that we should go to folder that script in. Let’s say

cd /home/anthony/proj

sudo python script.py

Do not forget add that between last if and “exit 0”. Other situation it won’t work.

What’s I2C?

I2C(Inter-Integrated Circuit) is the one of the protocol of serial communication. I2C requires two more connection for communication. These are SDA (Serial Data Line) and SCL (Serial Clock). For there is many connection I2C not for use far communications. I2C, usually used by developers for low data transfer and close communications.

At I2C there are master and slave part. Master control communication. For communication come true there should be at least one slave device. Master decide to transfer and control which slave should communicate with master. Because of this communication between more than 2 devices provided with only two connections.
