Introduction It’s time for 8-pin microcontroller Microchip PIC12C508, the SAVER V3.2, my latest design of a device that turns a night light on and off everyday. The circuit uses only a PIC12C508 8-pin CMOS micontroller and a small triac, MAC97A6. The Saver V3.2 also demonstrates the use PCW PIC C Compiler. Circuit Description The schematic […]

You might have come across several applications where we need to control a specific device based on analog parameter. This Embedded system works in a similar concept where we are about to control the speed of a DC motor using based on the external temperature. The rise in temperature will result in increase in speed […]

I was contacted by somebody who suggested I should enter our senior design project here. Seeing as how we found and used the AX-12s from Trossen Robotics, I figured this would be a great place to post. This project was our senior design, a semester long course that requires a team of electrical and computer […]

So you want to become a HAM, or you’ve got one of those no-code licences, but like me feel somewhat lacking,… not having obtaining that age old badge of proficiency that differientiated the HAM from other radio operators. However, like thousands and thousands of others, you have trouble learning the code. The problem for most […]

The 3rd harmonic distortion meter has been designed for measuring the quality of AC supply. The meter is built with a PIC18F2550 project board and the full wave rectifier front-end circuit. The AC power line, 220VAC is measured through the step down isolation transformer. The input signal to the 10-bit ADC is full wave rectified. […]

In the simple tutorial we are going to blink few simple led with PIC18F microcontroller, using an external 20MHz crystal oscillator and the ‘__Delay ()’ function of XC8 Compiler. Most of the previous tutorials here dealt with internal oscillator of pic18F4550 where mostly the delays were generated with simple for loops. However those who wish […]

1. Introduction Microwaves are maybe, one of the greatest discovers of the 20’th century. With a vavelenght between 30 cm and 3 mm and a power between 1 mW and 500 KW are practically used in all fields from medicine to industry. Microwave thermal and chemical tratments are well known for the high efficiency, with […]

Powersupply and CRT deflection and microcontroller test circuit. I was lucky to purcase two used but working DG7 tubes and a transformator cheap, one from Mullard and one from Phillips. Other CRT Cathode Ray Tube types can be used, you can even rip one from an old and maybe dead oscilloscope, then you also get […]

Following on from the LED flasher circuit, we can reduce the delay in the loop to 10uS (10 microseconds) and produce a 100Khz square wave. Given a 4 Mhz PIC 16C84, the program below will generate a 100Khz square wave on PORTA bit 0 (i.e. pin 17). This little program is useful for testing oscilloscopes […]
