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’ve already had a programmer for Atmel’s AVR microcontrollers, but I couldn’t use it in my lab, because my laptop doesn’t have a LPT port. So I decided to make a new programmer with USB connection. I’ve found an open source programmer AVR doper, and for the basis I took a modified version from the

I spent part of an afternoon developing a hardware RSS reader (most of my time was spent on the python side of things). It’s pretty simple and uses an AVR microcontroller connected to a computer via a serial cable Hardware I am using the Dragon Rider 500 as a development board. This provides all of

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

For this week I set out to make a board that will show realtime MBTA bus arrival times using the ESP8266 wifi module and a LCD. Seemed doable. People of the internet have been excited about the ESP8266 lately. Here is a snapshot of google trends for searches for esp8266 vs couple of other arduino

There was a thread on the Raspberry Pi forums about running a 16×2 HD44780 based display off the ATmega chip on the Gertboard. I normally use a shift register to run my display, so I wasn’t much help to them. I decided to try and get it setup without the shift register to help out

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
