In our previous two tutorials we discussed How to Get Started with PIC using MPLABX and XC8 compiler, we have also made our First LED Blinking Program with PIC and verified it by simulation. Now it’s time for us to get our hands on to the hardware. In this tutorial we will build a small […]

The graphene lightbulb has been the subject of a huge amount of speculation over the past few days. What is it? The truth is, nobody outside University of Manchester spin-out Graphene Lighting knows, so ignore anything you have heard or read. “As a scientist, I would love to say more, but for commercial reasons I […]

Dual DC Motor driver using two L293D IC. The L293D device is quadruple high-current half-H driver. The 293D is designed to provide bidirectional drive current up to 600mA a voltage from 5V to 36V. It provides 600mA +600mA on each channel suitable for mini hobby robots.  The board been designed mainly for small size robot, […]

In our previous tutorial, we learnt about Blinking a LED using PIC microcontroller and built the same circuit on Perf board. Then we used PICkit 3, ICSP and MPLAB IPE for dumping the program onto our Perf board. Now, in this tutorial we will advance our self to using more pins on the PIC microcontroller. […]

IP Cameras have become extremely cheap in the last couple of years. Mass production made the prices of decent quality image sensors, and very capable SoCs, drop significantly. Our victim in question is currently still available for about €43, but clones/copies/similar models are available from China for even cheaper. The cheap price is great if […]

This will be the fifth tutorial in our PIC Tutorial Series, which will help you to learn and use Timers in PIC16F877A. In our previous tutorials, we had started with Introduction to PIC and MPLABX IDE, then we wrote our first PIC program to blink the LED using PIC and then made a LED Blinking […]
