Lighting device

1. Introduction

To make the characterization of our biological system we develop a lighting device which can be controlled from a computer. The goal of this device is to create red and infrared pulses of which period and duration are fixed by the user in a computer interface.

The link between computer and the microcontroller is carrying through the serial port.

2. Printed circuit board

We design the printed circuit board with Kicad a free PCB design tool. You can download Kicad at this address:

Here you can download the PCB file of the circuit:

The following picture explains the different components used:

3. Microcontroller software

The microcontroller used is a Microchip pic 18F452 which is easily programmable in C language with MPLAB combined with C18 compiler.

Here you can download the hex file of the program:

And here are the source files of the soft:

4. Computer software

We develop the computer software with Microsoft Visual C++. You can download Express version at this address:

The following picture illustrates the software interface:

Here you can download the software:

And here are the sources files:
