Description This project is a crystal controlled precision timer providing accurate delays from 1 second to 15 hours 45 minutes.  The timer delay is set using a 10-way DIP switch.  The timer is started by pressing a switch on the main PCB or from an external switch connected via the terminal block connection.  A second […]

Description This project came about because I have three motorbikes and being a bit of a fair weather biker they don’t get used much over the winter months.  I have an OptiMate™ 4 charger that I connect to the bikes but this needs me to manually swap it from one bike to the next and […]

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. […]

This is an improved version of my 18-pin PIC16F series breadboard module that I have used in many of my PIC tutorials and projects published in this website. The new version has got a +5V power supply regulator on-board and a 2.1mm female barrel jack for DC input from a wall adapter. The 18-pin PIC16F […]

Introduction An HD44780 Character LCD is a liquid crystal display (LCD) display device designed for interfacing with embedded systems. These screens come in a variety of configurations including 8×1, which is one row of eight characters, 16×2, and 20×4. The most commonly manufactured configuration is 40×4 characters, which requires two individually addressable HD44780 controllers with […]

The 12F series of PIC microcontrollers are handy little 8-pin devices designed for small embedded applications that do not require too many I/O resources, and where small size is advantageous. These applications include a wide range of everyday products such as hair dryers, electric toothbrushes, rice cookers, vacuum cleaners, coffee makers, and blenders. Despite their […]
