The Carbohydrate Fermentation test uses Phenol Red Broth to test for the fermentation of different sugars. It is one of the fermentation tests, others include the Methyl Red test and the Voges-Proskauer test.
The main reason why we use hexadecimal numbers is because it is much easier to express binary number representations in hex than it is in any other base number system. Computers do not actually work in hex (donât laugh, beginning students do ask that question). Lets look at an example, using a byte.
Jan 12, 2013, 02:56 am. hi. hello. i have a question here. how i'm gonna send hexadecimal value to serial devices. i'm done a little bit study. the hex value can be send by using serial write like example below.he Arduino can not do two things at once. based on the rfid user manual that i read, in order to turn off the led of the reader, i need to send this command code via serial communication. AA BB 06 00 00 00 07 01 0 05. Packet Format (Hexadecimal): AA BB 06 00 00 00 07 01 LED XOR. AA BB = Header, 2 bytes.
