LCD Interfacing with AVR

Interfacing LCD Display in 8bit Mode I’ve already discussed about the LCD display in a note here in this website. You can read the Note on character LCD Display here. Now let us come to the interfacing side of LCD. Let us see the 8bit mode interfacing of the LCD display with an AVR micro controller first. I have added two circuits in this post 1) Interfacing LCD with Avr Atmega8 and 2) Interfacing with Atme ...

Interfacing LCD with ATmega32 Microcontroller

To establish a good communication between human world and machine world, display units play an important role. And so they are an important part of embedded systems. Display units - big or small, work on the same basic principle. Besides complex display units like graphic displays and 3D dispays, one must know working with simple displays like 16x1 and 16x2 units. The 16x1 display unit will have 16 characte ...

Interfacing 16X2 LCD to AVR Microcontroller

  Well this is not different from the way interfacing the LCD to 8051 or PIC microcontroller. The crystal oscillator will provide the clock to the microcontroller. The capacitors connected to the crystal will act as filters and help the crystal to resonate and oscillates to its parallel resonate mode.  The potentiometer which is connected to the pin 3 and pin2 of LCD will help to adjust the contrast of the ...

Ultrasonic Rangefinder HC-SR04 Interfacing with ATmega8

In this article I will describe how to interface a Ultrasonic Range Finder Module with a AVR ATmega8 microcontroller. I will provide a HEX file which you can burn into your ATmega8 directly to quickly test this whole setup. Ultrasonic range finder modules helps find the exact distance to an object. This can have vast application in robotics. These are more expensive than IR based obstacle detectors but the ...

Interfacing Serial Bluetooth Modem with Computer using ATmega16

This article would give you a general idea about how to setup and interface any Bluetooth modem with your computer. There are many types of Bluetooth modems available in market, which vary in quality, cost, range, etc. Some of the well known Serial Bluetooth modems are AUBTM, BLUESMIRF, RN-41, HC-05 and HC-04. I would be using the last one i.e. the cheap Chinese Bluetooth module. It has limited functions an ...

Interfacing GY 26 with atmega640

Hello friend once again with new instructable in this I will show you how to interface GY 26 with UART when I started working on this very less resource where availble over internet .Thus i thought to share my piece of work .GY 26 is a digital compass which gives angle with respect to earth north .it can be used for robot orientation and position aero model position and so on. GY26 uses UART or IIC for comm ...

Leonardo Arduino clone a single-sided PCB using ATmega32U4

DESCRIPTION This project is to make a clone of Arduino Leonardo in a simple way.That is why the distribution of the pin does not match the standard Arduino (have to make many jumpers on the motherboard or use both sides). However, most Arduino Leonardo characteristics are maintained. The circuit is protected by an automatic reset fuse (PTC) of 500 mA to prevent neglect we load up a USB port. The food select ...
