RC5 remote control using PIC12F629

All remote controlled projects from this site can be controlled with remote controls which use the RC5 protocol, like the TV-remotes from Philips. When all buttons from such a remote are in use then you could make a remote control by yourself. Your own build remote control with only one button or maybe you want to build a remote with more then hundred buttons. It is possible, however, you need the PIC Basic ...

RGB LED Mood Light Standalone PWM controller for RGB LEDs using PIC12F629

This project is an update to the original RGB LED PWM Driver.  The new version allows the use of either 5mm LEDs or the square bodied Superflux / Piranah style LEDs.  The circuit now uses bipolar transistors rather than MOSFETs which make it more suitable for novice constructors and for the first time this project is available as a kit with all parts required to assemble the PCB including the superflux LEDs ...

2 Digit Counter using PIC12F629 Microcontroller

This article describes a 2-Digit Counter using a Microchip PIC12F629. It shows what can be done with an 8-pin chip having just 5 output lines and one input line. The chip drives two7-segment displays and this would normally require 7 lines to drive the segments plus another one or two lines to select the displays. We have shown how a single line can be used to drive two different segments by using the tri-s ...

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. The input from the Joy Stick has been separated into two sections to make detection ...

4 ALARM SOUNDS using PIC12F629

This project is a miniature 1-chip alarm. All you need is a tilt switch, battery and piezo to produce a complete alarm. If you want a very high output, you can add a Darlington buffer transistor, piezo tweeter and a 10mH choke. The chip does all the work. It sits in sleep mode (100 microamps) and waits for the enable line to go high via the tilt switch. It then produces a SPACE GUN alarm for approx 3 minute ...

LED Strobe for PIC12F629

Description This project functions as a simple strobe for driving an LED.  The use of an output transistor allows it to pulse the strobe LED with a current up to 100mA. Four jumpers provide options for changing the pulse width, strobe repeat interval and single or double strobe flash.  The programmer ready code has default timings which are easily customised by editing values in the PIC's EEPROM at programm ...

PIC RGB Power Board using PIC12F629 microcontroller

Description Power Pic RGB is a circuit that generates random RGB colors using a powerful 3W RGB LED and fades between them. The initial project goal was to develop the fading algorithm which was successfully achieved. This time the idea was to drive a Prolight 3 Watt RGB LED and place it inside a nice white globe! On the right is a picture of the first prototype board eith a small board attached that doesn' ...

Long Period Astable Timer using PIC12F629

Description This software functions as a long period astable mutivibrator.  The mark and space period can be set from 1 second up to a maximum 65535 seconds (18h12m15s). Using the internal 4Mhz RC oscillator delays with an accuracy of 99% or better can be achieved  The code also implements an edge triggered reset and an active low hold function.  The reset edge can be configured for rising or falling edge.  ...

Whistle Key Finder using PIC12F629

This project uses one of the smallest chips in the PIC microcontroller range, the PIC12F629 and you can learn to program it and experience the thrill of making something yourself and see what goes into writing a program. Even a program as simple as this one is not easy to put together and if you are starting from scratch, you will need a programmer (a "burner") and all the data that goes with "burning" and ...

Capacitance Meter MkII using PIC12F629

This project is specially designed to measure surface mount capacitors in the range 1p to 920n and electrolytics in the range 1u to 100u. The biggest problem with surface mount capacitors .  .  .  they are not identified! And you cannot determine their value by the size of the component. This makes it very difficult. Unless you know the value when taking it off a reel, they can get mixed up and fitting a 22 ...
