Using PicBasic with the PIC16F84 PIC Microcontroller

PWM controller with PIC18f2455

The use of pulse width modulation (PWM) is common for the use of controlling power to a particular electrical device. Motor speed control, LED contrast control, power supplies are some of the example usage of PWM. 18 series PIC always come with a CCP module which is capable of generating PWM. The...

RGB LED PWM Driver

The circuit uses (RGB) Red, Green and Blue high brightness LEDs that are pulse width modulated (PWM) to vary the intensity of each colour LED. This allows effectively any colour to be generated with rapid changing strobe effects, fast and slow colour fades as well as static colours. The data...

testing Board for PIC12F683

This microcontroller fascinated me a lot because I wanted to see what we can do with an 8-pin microcontroller (out of which 2 pins goes to power supply, so actually just 6-pins are left for I/O). So I thought of making my own learning board for this. In this project, I am first going to describe...

4-digit Up/Down counter with PIC 16F88

This is a 4 digit decimal counter which can operate as a free running counter or in count and hold mode with manual reset. In either mode the counter can be preset to count to a specified value. Clock edge and leading zero suppression can also be configured. The 7-segment display and...

Classic PIC Programmer

This is my own version of the classic PIC 16C84/16F84 programmer. The design is originally by David Tait. I`ve made a few changes, redrawn the schematic and done a board layout. All the files you will need are linked below, including software you`ll need to operate it. The software is not by me,...

Saving the OSCCAL value for PIC 12F629 / 12F675

The PIC 12F629 and 12F675 have a factory set oscillator calibration value written to the last program memory location during manufacture. When programming the PIC the programmer software should read this value out, merge it with the program data being written to the PIC, and then write it back.

Digital clock with thermometer and hygrometer

I use a RealTimeClock Maxim DS1305. The RTC backup power is a supercapacitor (0,22F). I test it for 4 weeks, works fine. For this reason it don't have the capability to change the time, but you can do small-corrections. Once you push the button, the seconds change to 30, with no effect to...

PIC12C508A Beacon

Robot Beacon is a rotating light. We have called it Robot Beacon as it has been designed as an addition for a robot, but it can be used for many applications. It can be used as a mast-head beacon on a boat or as an "all-round" warning light on a bike. Robot Beacon uses a PIC12C508A OTP (One...
