PIC Pin Diagram: A printable copy for quick reference

PIC 18 Pin Diagram

Today when I was hooking up my PIC micro on to a breadboard for a quick demonstration to a friend of mine, I realized how often I needed the Pin Diagram from the datasheet. All this while I have been opening the datasheet and scrolling through to page 4. I don’t know about you, but, I bet there are a couple of people out there who did the same thing I did over and over again. You may have made a …

Standalone BreadBoard Breakout for PIC Microcontrollers

DSC09678

I wanted to make a breadboard breakout for PIC microcontrollers after seeing this arduino breadboard breakout from adafruit. This product is fully standalone and yet has very small footprint so that it can be conveniently plugged into the breadboard. The most amazing part was that it still had 2 rows on each side of the breadboard for the user to jump wires. First I thought of making a breakout board for the 40 Pin DIP package that I usually use. Then I realized …

Hack a Toy Car to Make a Cheap Wireless Robot

DSC09479

Hack a toy car to make a cheap wireless robot? Yes, cheap toy remote cars form china can be scavenged to get their remotes to work with our robots. All of us have seen and played with toy cars some time in the past. Some -like me- might have bought them to get the magnets inside those DC motors. I don’t know why those C shaped magnets caught my attention more than the car. I have to admit even after growing …

Interface – LCD in 4 bit Mode: Part 3

LCD in 4 bit mode pin connection

Embedded applications are always developed on controllers whose resources are almost fully used in order to cut the cost of the product. This is done especially in applications that do not need any future expansions or a firmware updates. They are Make-it and Forget-it kind of applications. Most of the time, either the memory or the available pins are in demand. In some cases both memory and pin count are less. The Character LCD in 8 bit mode uses 8 …

Interfacing LCD Module with Microcontroller: Part -1

lcd interface

The LCD module interface with a microcontroller is simple and it is a primitive means of adding a visual appeal to your embedded application. There are two basic types of LCD modules in the market they are, Character LCD and Graphics LCD. Character LCD’s are the some of the cheapest means LCD displays available today. This post is first of a series of four posts that walks through entire process of interfacing an LCD module with a (any) microcontroller with …
