Introduction Our project consists of making a reflow soldering device using a normal toaster oven with a graphical LCD display for control and GUI. Soldering is an important and difficult task for custom printed circuit board design especially for integrated circuits that come as chip packages that are impossible to solder by hand. This is […]

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.

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 mpd, the music
