Make Your Own Watch

The project main aim is to make a programmable watch which will have a four character display and can display anything from song lyrics to numbers to foul language and yes time too. The display is a four character based display made up of 5×7 led matrices. The input data line is 7 bit. However there is no need to for any current limiting resistors, pull-ups or even upper and lower case characters.

The intelligent display is known by DLO3416 which is made by OSRAM semiconductors limited and is available in red, green walnut flavors. The microcontroller used is PIC16428A which is manufactured by Microchip and is easily available online or even at local hobby shop. In addition to the microcontroller, there is a charge pump also used which is known by MCP1253. It’s used to make a 5V display from a 3V coin cell battery. You might need a couple of those for backup. The other thing which are required are resistors and capacitors and most importantly a PIC programmer along with some sockets and jumpers
