<p style="color: rgb(0, 0, 0); font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; letter-spacing: normal;">This is your tried and true white solderless breadboard. It has 2 power buses, 10 columns, and 60 rows - a total of 800 tie in points.</p><p style="color: rgb(0, 0, 0); font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; letter-spacing: normal;">All pins are spaced by a standard 0.1". The two sets of five columns are separated by about 0.3", perfect for straddling a DIP package over. The board accepts wire sizes in the range of 29-20AWG.</p><p style="color: rgb(0, 0, 0); font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; letter-spacing: normal;">This board also has a self-adhesive on the back. The boards also have interlocking parts, so you can hook as many together as you’d like.</p>

A 16x2 LCD display is very basic module and is very commonly used in various devices and circuits. These modules are preferred over seven segments and other multi segment LEDs. The reasons being: LCDs are economical; easily programmable; have no limitation of displaying special &amp; even custom characters (unlike in seven segments), animations and so on.</p><p style="color: rgb(0, 0, 0); font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; letter-spacing: normal;">A 16x2 LCD means it can display 16 characters per line and there are 2 such lines. In this LCD each character is displayed in 5x7 pixel matrix. This LCD has two registers, namely, Command and Data.</p><p style="color: rgb(0, 0, 0); font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; letter-spacing: normal;">The command register stores the command instructions given to the LCD. A command is an instruction given to LCD to do a predefined task like initializing it, clearing its screen, setting the cursor position, controlling display etc. The data register stores the data to be displayed on the LCD. The data is the ASCII value of the character to be displayed on the LCD.
