Joy Stick Controller

Joy Stick Controller using PIC12F629

This project controls two servo motors – both clockwise and anticlockwise and has variable speed. You can use the Joy Stick to “pan and tilt” a remote camera or provide “left-right-up-down” action for a crane or an animation on your model layout. The project also tests servo motors. The CIRCUIT The circuit is fairly simple. […]

Mars Clock

Mars Clock using PIC16F877A microcontroller

What do you do if you have a spare LCD module with backlight, a weird 16 button keyboard, and a PIC16F877A microcontroller gathering dust? A monster Martian Clock immediately springs to mind. You are probably thinking “There are hundreds of PIC clocks on the Net – do we need yet another one?!” Well, this one […]

LED Christmas Cards using PIC 10F200

LED Christmas Cards using PIC 10F200

This is an instructable on how to build an LED Christmas card using the PIC 10F200 microcontroller. As this PIC has six pins and is the size of an SMD transistor, it is ideal for low profile applications and can easily be reprogrammed as and when needed. In this case I am using the “reverse […]

4x4 Matrix Keypad

Interfacing Matrix Keypad with PIC Microcontroller

This tutorial explains ‘What is a Matrix Keypad ?’ and ‘How to Interface Matrix Keypad with PIC Microcontroller ?’. Matrix Keypad Matrix Keypad is a very useful and userfriendly when we want to design certain applications like Calculator, Telephone etc. Matrix Keypad is made by arranging push button switches in rows and columns. Just imagine, if you want […]

Make it on a breadboard

The simple Joule Thief

The Joule Thief is such an easy and simple device, but what it does is amazing. It can use a battery that is not usable in any other electronic device and give it life again. It can even take a battery that won’t even power a basic LED by itself when it is brand new […]

Interfacing Real Time Clock RTC DS1307 with PIC Microcontroller

Interfacing Real Time Clock (RTC) DS1307 with PIC Microcontroller

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 […]

Aurora 48 48 RGB LED Sequencer using PIC24FV16KA304

Aurora 48 – 48 RGB LED Sequencer using PIC24FV16KA304

Aurora 48 is a compact and thin profile full-color LED sequencer. It’s built entirely with surface mount components, so the profile is nice and clean. Features Capable of individually controlling 48 Full color LEDs. Each LED can be faded in 7 bit per channel – 2,097,152 colors. Gamma corrected brightness curve for very smooth fades. Simple, […]

DC Motor Speed Control using PWM with PIC Microcontroller

DC Motor Speed Control using PWM with PIC Microcontroller

I already posted about Interfacing DC Motor with PIC Microcontroller. In our robotics applications we may have to control the speed of the DC Motor. In this tutorial we will see how to control the speed of a DC Motor using Pulse Width Modulation (PWM). By using PWM we can easily control the average power […]

Stepper Interfacing Stepper Motor with PIC Microcontroller

Interfacing Stepper Motor with PIC Microcontroller

Introduction A Stepper Motor is a brushless, synchronous DC electric motor, which divides the full rotation into a number of equal steps. It finds great application in field of microcontrollers such as robotics. Please refer the article Stepper Motor or Step Motor for detailed information about working of stepper motor, types and modes of operation. Unipolar Motor […]
