Interfacing 7-segment display with PIC12F1822 using CCS PIC C compiler

The easiest way to interface 7-segment display with PIC12F1822 microcontroller is to add a serial-in parallel-out shift register. The adding of the shift register minimizes the number of pins used by the 7-segment display. This topic shows how to make a 3-digit digital counter with multiplexing and 74HC164 shift register using PIC16F877A and CCS PIC C compiler. Interfacing PIC12F1822 with 7-segment display  ...

Red Light for Astronomy Observing using PIC12F683

When doing astronomy observing at night preserving night vision is critical. This requires using the minimum amount of light that makes the sky charts readable. What is this minimum level depends on how dark are your surroundings, how much time you have spent in darkness, how well your eyes adapt for night vision, what type of charts are you using, what object are you observing, and so on. My old astronomy ...

Skateboard with PIC microcontroller and LEDs

What do you get when an Electrical Engineer builds a Skateboard from scratch for a 13 year old's Christmas present? You get a skateboard with eight white LEDs (headlights), eight red LEDs (tailights) all controlled via PIC microntroller! And I might add, one very happy 13 year old, well as happy as a 13 year old can be. Following is how I modified a skateboard kit (from ROAROCKIT.COM), added LEDs to the fro ...

Pimp My Rocket (Espresso Machine)

Combining Coffee and Electronics – An Idea for a Project Having played around with fixed function logic ICs, such as the Johnson counter used in the Spindicator project, I was keen to move on and experiment with programmable microcontrollers. I decided to obtain and play with some PICAXE chips, as they looked like they would provide an easy introduction to using microcontrollers. Soon enough I was flashing ...

Knight Rider Light computer – version 2

This knight rider light computer is a successor of my first version of the Knight Rider. This version is much smaller and justifies the use of a microcontroller. The project is based on the PIC 12F629 microcontroller. The hardware part Unlike my previous project this light computer is build around the PIC12F629: a microcontroller with only 8 pins. It is shipped in a DIL-8 housing. An external clock is not n ...

RGB REMOTE (pinguino+web+linksys) using PIC18F2550 microcontroller

RGB REMOTE (pinguino+web+linksys) This project has several uses, it is basically a way to control an RGB LED group (tricolor with common ground) via a web page to select which color we want to show. It may be a way to harmonize a room, change the color of a swimming pool or just fooling aroun Step 1 RGB REMOTE webserver and serial connection In my case the web server is in Linksys router which I have "hacke ...

Easy Way to Design an Automatic Driverless Train

Every one in the metro cities like Kolkata, Delhi enjoying the luxuries of the metro train ever spared a thought about the train? No, then let me give you a brief idea about the driverless automatic driven and controlled train. But before that let us have a brief recall about types of metro automation. The Driver Controlled Mode: In conventional modes, it’s the manual driver who drives the train and control ...

How to take input with PIC18F4550 Microcontroller

Any microcontroller based system typically has an input and a corresponding output. Taking simple output with a PIC microcontroller has been explained in LED blinking with PIC18F4550. This article explains how to provide an input to the controller and get a corresponding output using PIC18F4550. PIC18F4550 has a total of 35 I/O (input-output) pins which are distributed among 5 Ports. Each Port of a PIC micr ...
