SignGlove What is SignGlove ??? SignGlove is an innovative wearable glove designed to bridge the communication gap for paralyzed patients, enabling them to express their wants and needs through hand signals. It enables caretakers to understand and respond to the needs of individuals with limited mobility.  Over a Wi-Fi network, SignGlove allows users to transmit their hand signals directly to a caregiver's device. One of the key features of SignGlove is its configurability, which allows it to adapt to each user's unique abilities and hand gestures. By customizing the device to match the specific range of motions and signals that a user can comfortably make, SignGlove ensures a highly personalized and tailored communication experience.  With SignGlove, paralyzed patients no longer rely solely on non-verbal cues or guesswork to convey their needs. The SignGlove concept ...... The concept of SignGlove was inspired by the work of Navid Azodi and Thomas Pryor from...

I am using the AT89C51 to interface the 4x4 Matrix Keypad and display the Input on a 16x2 LCD Display. The tools I will be using are : Keil uVision 5 Proteus 8 Professional The LCD is operated in 8 bit mode to display the key that is pressed. The keypad is connected to  Port-1 and the LCD is connected to Port-2 [Data Pins : D0-D7].  Initially the keypad is connected such that Row pins are LOW [ 0 ] and Column pins are HIGH [ 1 ]. Whenever a key is pressed, it will short the circuit and gives the Column a LOW. Then a function is called to check which ROW that key belongs to. For this purpose, we use four user defined functions to determine the ROW number. NOTE : Here the key should be pressed down for 2 seconds to display the input on the screen. This can be debugged along the way. _______________________________________________________________________________ Code : Embedded C IDE : Keil uVision 5 Simulator : Proteus 8 Professional uController : AT89C51 /* Created  by mbe...

I am using the AT89C51 to interface the 16x2 LCD Display. It will be a minimal display message. The tools I will be using are : Keil uVision 5 Proteus 8 Professional The LCD is operated in 8 bit mode to display two lines of messages under 16 characters. When interfacing with an LCD screen only, it doesn't matter the communication mode. When incorporating other modules and shields, we require other port pins for various usage. There I will be demonstrating the 4-bit mode. In this article, I will be demonstrating two operations : Static 2 line message display Scrolling 2 line message display The circuit will be the same for all modes and there will be minor changes in the code. I will be adding the Scrolling Text mode in the LCD screen in the coming days. ___________________________________________________________________________________ STATIC MESSAGE DISPLAY ON 16x2 LCD SCREEN ___________________________________________________________________________________ Code : Embedded C IDE ...
