A PIC Serial LCD Project

This project shows you how to create a serial LCD module that you can drive from any serial RS232 interface. You may be asking yourself why is this project using RS232 when computers are no longer even produced with a serial port as standard? There are three reasons: Most microcontrollers come with a UART built-in as […]

A PIC Ultrasonic distance meter project using a Seven Segment display and a PIC micro

A PIC Ultrasonic distance meter project using a Seven Segment display and a PIC micro.

The PIC Ultrasonic distance meter works by transmitting a short pulse of sound at a frequency inaudible to the ear (ultrasonic sound or ultrasound). Afterwards the microcontroller listens for an echo. The time from transmission to echo reception lets you calculate the distance from the object. PIC Ultrasonic Distance Meter Specification Range ~5cm – 300cm

Serial LCD Controller

Serial LCD Controller

I discovered a flaw in the current design that will only allow the controller to work with a connection to the computer and not to a microcontroller.  I’ve updated the schematic below and will fix the controller design.  I’ve added a project file below that also includes the fixed schematic. If you look at the
