How data encrypt and decrypt from PC to PC using micro controller?
Measuring strain using micro-controller is simple and easy. When measuring using micro-controller you use points and condensers.
how temperature is measured using 8051 micro-controler?
yes
The Enigma machine was used during World War II to encrypt and decrypt secret messages by using a series of rotors to scramble the letters of the message. The machine had a different setting each day, known only to the sender and receiver, making it difficult for enemies to decipher the messages.
yes
because in atmel .............it is easy to program and troubleshooting
We'll use a simple method of encryption: xor encryption // same function used to both encrypt and decrypt void crypt(char *str) { const int key = 0x86; // crypt each individual character of str int i; const int length = strlen(str); for(i = 0; i < strlen(str); ++i) { str[i] = str[i] ^ key; } }
You can encrypt pictures using the Encrypt4all program.
By using buffer along with micro-controller, it is possible to reduce the effect of 'back EMF' or 'Spiking Effect'. The capacity of any micro-controller is to sink or source current up to 25mA and its ports gets damaged if it is more. So buffer protects ports of micro-controller getting damaged. And it is possible to get appropriate data trans-receiving by using buffer in micro-controller.Sachin Joshi
Yes.
Microcontroller have inbuilt memory, interrupts, etc. Which you will need to connect externally in microprocessor. Thus, Microcontroller is better than microprocessors
Google doesn't give this feature directly but there are apps such as Innovode Armor that can password protect files and documents. Alternatively to password protect a google spreadsheet you can use google scripts. Using scripting there are two options - encrypt and decrypt. You need to set a password first. Once you encrypt, all the text will be obfuscated and unreadable. To read it, you need to decrypt it again with the same password.
