In the following topic URL we’ve seen how to control BLDC motor speed and direction of rotation using PIC18F4550 microcontroller and 3-phase bridge circuit:CD-ROM Spindle motor (BLDC) control with PIC18F4550 microcontroller This topic shows how to make the same controller using L293D motor driver instead of the 3-phase bridge circuit. The 3 phase bridge is […]

This post shows how to connect ST7735S TFT display to PIC18F4550 microcontroller and display different things (numbers, text, lines, circles …..). The compiler used is CCS PIC C. To interface PIC18F4550 with the ST7735 TFT display we need a small library (driver) which can be downloaded from its original post at the following url: ST7735
(Some knowledge about RC-5 protocol is required) This project shows how to build a remote controlled real time clock with TFT display using PIC18F4550 microcontroller. In this project DS1307 RTC is used as a real time clock chip and the remote control is an IR (infrared) remote control which uses RC-5 communication protocol, this remote

This example shows how to display Bitmap (BMP) image files from SD card on ST7735 1.8″ (128×160) TFT screen using PIC18F4550 microcontroller and CCS PIC C compiler. To build this project we need the ST7735 TFT driver, SD card driver and FAT16 library. The three source files must be added to the project folder (or

1. Quite a few POV clocks out there, why is this special? Well, mainly because it’s mine. There are quite a few POV clocks out there on the web using all sorts of display mechanisms, chassis, controllers. The one I decided to build isn’t exactly one of them, the main difference being in the way
This is my attempt at designing and building an obstacle avoiding robot! RekaBot (named after a fairy (: ) can detect obstacles with an ultrasonic sensor that can move around with help from a servo. Based on the measurements she takes, the tracks are driven towards the direction with the biggest distance – avoiding obstacles.
The 16×2 character LCD can also be used to display custom characters other than numerals, alphabets & special characters. Refer LCD interfacing with PIC. Some special shapes like hearts, arrows, smileys etc. can easily be displayed on the 5×8 pixel pattern of character LCD. These shapes are first stored at a special location in LCD’s
