Testing RF Transmitter and Receiver Circuit

After publishing the article Make a simple RC car I have received a lot of comments and e-mails from readers who have faced some difficulties while trying to make the circuit by themselves. I have complied a small list of testing methods for various components that will help your narrow...

Circuit Debugging - Tips Tricks & Techniques

Here we are with a TTT (Tips, Tricks and Techniques) post again after a long time! Firstly I have to apologize for the recent inactivity in the blog. I’ve been a little busy over the last few months. But guess what! I have some good news! I think I’ll soon...

PIC Pin Diagram, A printable copy for quick reference

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...

Reading datasheet, what to look for and how to find them

Did you know that experienced engineers spend up to an hour on every major component that they are going to be using for upcoming projects? Project as in, real commercial work involving a lot of money and man hour.. not just some hobby project. When a component is being purchased...

Graphic LCD Command Sheet HTML Version

Yet again I was looking for the GLCD command sheet in the internet and failed to find any good resolution images that I can use for post references. Even the data sheet looks really bad. So here I am with a HTML Version of the GLCD command sheet just like...

How To Breadboard Power Supply

Most of the time your breadboard will just need a 5 volt supply to power all the components. Very rarely you might need a 12 volt (if you are driving loads like motors) or 3.3 volt (devices rated at 3v3). In this post we will see the making of a...

Getting Started with PIC Microcontrollers

Having worked with any one Microcontroller, moving from one of its family to another is just a matter of knowing the right tools and understanding how things have to be done in terms of software (compiler specific addressing like that of the SRFs) and hardware (circuitry, design practices, etc., )...

PIC Timer Calculator

Timers are one of the mostly used modules in microcontroller. Almost every system that has to reliably produce time interval or delays will have to use timers modules. The PIC timer calculator is a cool tool that will make life much simpler. If you haven’t worked with timers, I suggest...

Cool C Programming Tricks For Embedded Software Developers

Proficiency in C is an essential skill set for embedded software developers. In this post we will see some really cool C programming tricks that you should have already known. If you didn’t, it’s time to take a pen and paper. Be warned this is just a small collection of...

Interrupt On Change (IOC) in PIC Microcontrollers

The interrupt on change is a cool feature on microcontrollers. Like you guessed, the interrupt occurs when there is a state change in any of the port pin associated with this feature. In PIC microcontrollers, PORT B has the Interrupt on Change feature. The controller jumps into the interrupt vector...
