IKEA Mood-light Conversion using PIC12F683P

Introduction This little project was one of my first projects with microcontrollers. First, I made the circuit then, for years, I was wondering what I could do with it, until one day I came across this IKEA plastic bag dispenser. I knew immediately, it would make a perfect “housing” for my mood light. Hardware I had a few LED strips leftover from previous projects in different colours. They can be operated ...

Color Globe using PIC16F688 Microcontroller

This was a fun little project I put together in a few hours for a homemade-themed gift exchange this Christmas.  I had on-hand a "Full Color LED" from Radio Shack (part 276-0028) which caught my eye on my last visit there. The LED has a common anode and three cathodes, one for each of the three primary colors: red, blue and green.  By changing the duty cycle (the fraction of time the pin is low) on each of ...

IR On/Off Switch Using Microcontroller

Turn ON or OFF electrical devices using remote control is not a new idea and you can find so many different devices doing that very well. For realization of this type of device, you must make a receiver, a transmitter and understand their way of communication. Here you will have a chance to make that device, but you will need to make only the receiver, because your transmitter will be the remote controller ...

Embedded System for Automatic Washing Machine using Microchip PIC18F Series Microcontroller

The design uses the PIC18F series microcontroller. All the control functionalities of the system are built around this. Upgradeability is the unique feature of this system. Control card hardware and software allows the manufacturer to add or remove the features as per customer requirement and model. Thus once the whole system is designed it is very economic in large quantity production. Single-phase motor i ...

Smart Button using PIC10F microcontroller

Smart Button This is a button a little bit smarter. (Microcontrollers and coffee, who doesn't like) I i'm using it to fill my Coffeemaker  with water. This way its a little bit more fun and i always get the same amount of water. Its a simple project, and it's a good excuse to play with a PIC10F, one really small micro-controller. Code is written in C, a nice way to start with it. It interfaces with the user ...

APPLICATION OF MICROCONTROLLER IN AUTO DETECT DOOR OPEN AND PAPER JAM ERROR using pic microcontoller

Microcontroller was invented by Intel sometimes in the 80s ever since that invention other Electronics companies such as Atmel, Microchip and Motorola etc have manufactured different brands of Microcontroller like AT89, PIC16F and 68H All microcontrollers performs specific task based on the set of instructions giving to them through a process called Programming language. Example of programming language incl ...

Telephone operated remote control using PIC16F84A microcontroller

This design controls up to 8 devices using a PIC microcontroller (PIC16F84A) connected to the phone line. The unique feature here is that unlike other telephone line based remote control, this device does not need the call to be answered at the remote end so the call will not be charged. This device depends on number of rings given on the telephone line to activate/deactivate devices. 1. Circuit diagram (de ...

Enhanced 5/2-day Central Heating Programmer with serial computer interface using PIC16F628A

Overview This project has come about from my desire to control my home heating from work.  As I have a VPN between work and home a straightforward relay controlled from a PC would seem the easiest solution.  However I also wanted a control unit that I could operate in the house without resorting to the computer.  For example, I get up late and the heating is off, I just want to hit a button and turn it on.  ...

Leaving home light using PIC12F675 Microcontroller

Those days when I come home at night and strait into the darkness are finally over. This is a very practical device and I built it so that it is a module to my Dual Channel IR Remote Control. Because of that I ended up with a definite overkill of what is supposed to be a simple switch with a timer when I open/close my door. Anyway, it is modular+wireless and that's what I like. You can download the project ...
