When you are using LCD in 4 bit mode you have to send data two times where in 8 bit mode you only have to write once, this ultimately keeps your microcontroller more busy with LCD. If you are doing only a few things with your microcontroller then its ok you.... -

This post is based on the work made previously by tomek in wiring LCD displays using 4 bits. The basic idea is to group the 7 pins that are needed to drive the LCD in only 3 using a shift register. This is a cheap alternative to serial LCDs. The schematic.... -
This is the first color, graphic LCD display I worked with. I made some assumptions when I first began working with it. From previously working with TTL logic in college, I assumed CS and RESET could just be tied high for simplicity. It wont work if you do.... -
LCD comes in various configurations and the most popular one is 16x2 matrix display. This article shows the interfacing of ATmega16 with LCD by displaying a simple character on the LCD. In this project LCD is working in 8-bit mode i. e. , the data.... -
This really a work that so cool if you like modif PC. So this is a USB interface for alphanumeric LCD display like 4 G— 20 which can be controlled with LCD Smartie program. USB interface is implemented by using PIC18F2550 microcontroller, Using USB LCD.... -
The 2 X16 Parallel LCD is an 8 bit or 4 bit parallel interfaced LCD. This unit allows the user to display text, numerical data and custom created characters. The LCD uses the HD44780 series LCD driver from Hitachi, or equivalent controller. The LCD is.... -
The LM35 of National Semiconductors that is used in this project is a precision centigrade temperature sensor, which has an analog output voltage. It has a range of -55 C to +150 C and an accuracy of ±0. 5 C. The output voltage is 10mV/ C. The output voltage.... -
How to connect a LCD display to an Arduino and test it. This tutorial shows beginners how to use a breadboard to connect an LCD display to an Arduno, step by step.... -
A temperature sensor (MCP9700 linear active thermistor IC) and LCD are connected to the Arduino in this tutorial. The Arduino reads the temperature from the MCP9700 on analog pin A0 and displays the temperature on the LCD.... -

The EN line is called `Enable`. This control line is used to tell the LCD that you are sending it data. To send the data to the LCD, your program should make sure this line is low (0) and then set the other two control lines and/or put data on the data bus..... -
INTRODUCTION It is very important to keep a track of the working of almost all the automated and semi-automated devices, be it a washing machine, an autonomous.... -
An LCD -liquid crystal display is an electronically-modulated optical device made up of any number of pixels filled with liquid crystals and arrayed in front of a light source (backlight) or reflector to produce images in color or monochrome. The block....

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.....
