Description This neat little circuit provides 8 LEDs directly driven from the PIC along with a single mode control switch. The firmware elsewhere on this page drives the LEDs with a 5 bit PWM signal providing each of the 8 LED channels with four levels of intensity; off, dim, mid, bright. A number of sequences […]

High-level Design The goal of this project is to create an electronic flute. The musical instruments like keyboards, guitars, etc. have adjustable keys in order to play sounds at different scales. However, flutes are designed for only one scale and therefore need to be changed to play music on another scale. Hence, our electronic flute
Overview This is a building block project I developed to try out a few ideas. It decodes a 4-bit binary word to outputs that will drive a 7-segment LED display. Functionality is similar to the 7447 BCD-to-seven-segment decoder/driver IC however, because it’s implemented using a microcontroller, the segment control data can be customised to display

The original DMX512 driver project #800 is now redesigned to incorporate the optional address configuration switch on the main PCB. The no-switches in-band DMX configuration feature is still retained Double sided PCB has resulted in a more compact board size. Firmware has been updated to run a latest generation enhanced midrange PIC16F1823 processor.

Recently I acquired a 5M length of RGB LED strip using SMD5050 RGB LEDs. It has built in current limit resistors designed for operation from a 12 volt supply. Having thought this would directly attach to the Picprojects MOSFET RGB LED driver project I went ahead and bought one only to discover when it arrived

Overview In this project, we create a mesh network of PIC32 microcontrollers connected using ESP8266 wifi modules. The mesh network is able to fully connect itself through a variety of graph topology algorithms and is able to route packets through the network using a shortest path approach. It also exposes a very simple application layer
