This project is pretty cool for a few reasons, and driving a huge LED matrix with a single 8-bit controller is just one of them. The idea was born when I bought 120 LEDs of the wrong type, and decided to do something with them. With that many LEDs, there are only a few things […]

This is our PIC Microcontroller tutorial series. We have already discussed basic beginners guide to PIC. Now let’s see how to simulate the PIC microcontroller?PIC simulation is the important step that you should do before practical implementation of any microcontroller projects. As Circuits Gallery covers topic of Microcontrollers especially with PIC (Peripheral Interface Controller), this

This article shows how to use the PIC16F84 microcontroller with PicBasic to design a quick & effective, serially controlled, I/O-Expander. Using PicBasic makes developing handy single-chip devices like this extremely simple. If you’re spending all your time programming in assembler, you’ll appreciate how simple PicBasic is to use, and how easily you can create single-chip

Have you ever thought that most of our perception about the robot is based on the Hollywood movie! The famous 3CPO and R2D2 from Star Wars until the little cute garbage compacting robot named WALL-E; all of these machines are example of our dreams or should I say our quest to what we all think
The AquaCont is an electronic system witch permits to manage and to monitor most of the parameters of all the electrics devices that can be found in a aquarium. The PIC18F4520 used to realize it, combines a real time clock and a temperature sensor in order to control 8 relays. The system main characteristics are:

What do you do when you have to read the internal ROM contents of a 8048 or 8049 processor and you don’t own a programmer for those devices? You simply build this 8049 spy of course! That is exactly what I did when I wanted to know how my Philips Frequency Counter PM 6668 worked.
A relay is an electromagnetic switch which is used to switch High Voltage/Current using Low power circuits. Relay isolates low power circuits from high power circuits. It is activated by energizing a coil wounded on a soft iron core. The Role and Function of Relays include controlling the flow of electricity between circuits, providing electrical

DS1307 is a low power serial real time clock with full binary coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM (Non Volatile Static Random Access Memory). Data and Address are transferred serially through a bidirectional I2C bus. The RTC provides year, month, date, hour, minute and second information. The end date of months is automatically adjusted
