Keyboard Board Arabic Alphabet
The reason is the battery charger on board for Adafruit module I read the whole data sheet but i am confused about the pins i can use without any conflict. On the DOIT i had, first a membrane keypad. 4 Outputs for horizontal lines with the following GPIO: KH1-26 KH2-19 KH3-18 KH4-23 3 Inputs for vertical line. Each line is pulled up by 1K. To use the numeric keypad to enter numbers, press Num Lock. Most keyboards have a light that indicates whether Num Lock is on or off. When Num Lock is off, the numeric keypad functions as a second set of navigation keys (these functions are printed on the keys next to the numerals or symbols). The Best on the Internet! Type, Translate, Search, Send emails, tweet, and share with your friends in facebook with this online onscreen virtual keyboard emulator, in all languages.
