As we all know LCD (Liquid Crystal Display) is an electronic display which is commonly used nowadays in applications such as calculators, laptops, tablets, mobile phones etc. 16×2 character LCD module is a very basic module which is commonly used by electronic hobbyists and is used in many electronic devices and project. It can display 2 lines […]

Some time ago I’ve build a prototyping board with graphical LCD. It have served for various small projects and prototypes. Had a spare temperature sensor DS18B20 and decided to put simple temperature display project. GLCD board is equipped with Atmega32 microcontroller running at 16MHz. DS18B20 sensor is connected to port D pin 6. LED connected

In this project, we will learn How to design an Accelerometer and Relay based Hand Gesture Controlled Wireless Home Automation System with AVR ATmega32 microcontroller using 433MHz RF. Here, we will use different hand gestures as input signal to control the appliances i.e 2 bulbs and 2 fans. Also, we will display the status of
lcdmenu1 is a simple and small lcd menu builder for AVR Atmega. It works with only 4 buttons (up, down, right, left), additional buttons can be added. It can also store values to eeprom User can use button up and down to list menu categories, right and left to browse child and parent. If an item

I considered subtitling this article, “adventures in breadboard noise”, since that’s what I spent most of my time dealing with. In any case, let’s recap where we were. Veronica’s video generator was generating a stable VGA signal. In addition, a test pattern was being displayed by altering pixel colors on the fly during the scanning
This is the seventh part of an ongoing series about building a low cost, open source streaming internet radio. If you haven’t already, check out the previous parts (see the links at the end of this article) for some background about the project. In part six, we used OpenWrt’s UNIX-style shell commands to interface with
