using only total of 7 pins from your microcontrollers GPIO. So LCD module will cost only single port out of fours. >> The EN line is called "Enable. " This control line indicates to the LCD that we are sending it data. To send data to the LCD, the EN should.... -
The RW line is the "Read/Write" control line. When RW is low (0), the information on the data bus is being written to the LCD. When RW is high (1), the program is effectively querying (or reading) the LCD. Only one instruction ("Get LCD status") is a read.... -
An LCD basically consists of two glass plates with some liquid crystal material between them. The LCD has an electrically controlled light polarising liqui.... -
LCD (Liquid Crystal Display) is an electronic display which is commonly usednowadaysin applications such as calculators, laptops, tablets, mobile phones etc. 16G—2 character LCD module is a very basic module which is commonly used by electronic hobbyists and.... -
16G—2 character lcd display is very basic module which is commonly used in electronics devices and projects. It can display 2 lines of 16 characters. Each character is displayed using 5G—7 or 5G—10 pixel matrix. Interfacing 16G—2 LCD with 8051 using Keil C.... -

In the circuit shown below i have configured the LCD module Command Register at address 00H and Data Register at 01H, so when ever we will write the data at address 00H, it will be considered as command for LCD, and when ever at 01H, it will be considered as.... -
Alphanumeric LCD displays have become very popular for microcontroller applications because they can add a lot to a project in a variety of different ways. A text message giving the user instructions as well as feedback can make the application seem much.... -
Here is an example which implements a clock in just 36 lines of perl code. It displays time and date and the upper right corner shows a little icon called "heartbeat". The "heartbeat" is added by the LCDd server. This "heartbeat" icon blinks once in a while.... -
The Intersil ICL7106 and ICL7107 are high performance, low power, 31/2 digit A/D converters. Included are seven segment decoders, display drivers, a reference, and a clock. The ICL7106 is designed to interface with a liquid crystal display (LCD) and includes.... -
The LCD module has built-in fonts and can be used to display text by sending appropriate commands to the display controller, which is called HD44780. Detailed information for using the display is available in its datasheet. A schematic diagram of the LCD.... -
This LCD terminal provide two modes of operation by selecting jumper J1. When J1 is open the terminal operate as a normal ascii display terminal, when J1 is closed the terminal displays the input serial data in hexadecimal format. This mode is useful for.... -
The enable signal for USB chip and GLCD controller were made by PLD decoder from the address lines. As we have seen the memory map for i/o of 8051SBC board, the available space is from 0x0300-0x07FF. The address range of 0x0300-0x03FF was used for USB chip.... -
To do this, first, we must make the appropriate physical connections from the arduino board to the LCD. Then after, we must write the code so that whatever text we want displayed comes up on the LCD. LCDs are pretty much the standard now in order to display.... -
With the 10KG potentiometer, you can vary the contrast from dark to bright. When the potentiometer is near 0G , the screen will be very dark. As you turn the potentiometer up to 10KG , the screen will become brighter. .. -
The adjustment control for the contrast of an LC-Display is typically a 10-k potentiometer. This works fine, provided that the power supply voltage is constant. If this is not the case (for example, with a battery power supply) then the potentiometer has to.... -
Library routines for 3-wire LCD interface based on 74HC595 shift register. More details are provided in the attached ReadMe document or posted at Do you want to unsubscribe in order to stop receiving notifications regarding "MikroC Pro for PIC driver routine.... -
This article is the result of the very positive feedback on the hardware articles that I have written so far. You LinuxFocus readers are really a great audience! Some of you wanted to know how to interface the USB bus. So here is a nice solution. We use the.... -
This article continues the AT90S4433 Microcontroller series. I suggest you to read the previous articles on Atmel Microcontroller programming with regards to: This time we design a frequency counter which can measure frequencies from 1Hz to 100MHz..... -
The following are detailed schematics for the QScreen Controller. The QScreen Controller combines an embedded computer based on the 68HC11 microcontroller with a touch panel and LCD (liquid crystal display) graphic user interface ( GUI ) that is ideal for.... -

This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is.... -
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to.... -
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This.... -
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the.... -
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
