Picaxe Projects #1: Making Fast Printed Circuit Modules

Experimental circuit board modules can be made quickly and fairly easily. They have the advantage of being more than twice as fast to build than a custom circuit board. They are also easy to test in a breadboard. The modules detailed here are ones I have made using various Picaxe microcontrollers. Step 1: Picaxe Project Modules Pic2 shows a few of the Picaxe modules that I have built and tested that use the ...

PIC18 Development Board with Ethernet and USB

In this instructable I'm going to show you how to make your own PIC18 development board that features both Ethernet and Full Speed USB 2.0 at a low cost. Features: The development board is based on a PIC18LF4553 microcontroller. The microcontroller features a Full Speed USB 2.0 (12Mbit/s) interface without the need for any external components. Also, it has 32KB of program memory, 2KB of RAM and it supports ...

PIC16F1787 Programmer Board (for Almost all 40 pin 16Fxxx)

Intro This is my first Instructable so I'm sorry for mistakes. Critics are always welcome :) So in this project I made a development board for PIC16F1787. Now most of you guys aren't familiar with this particular model. Some might even think why I chose 16Fxxxx series IC when I could have easily used 18Fxxxx series and had more fun. Well for my project DC to 3 phase AC pure sinewave Inverter (I'll try to ma ...

chipKIT Tutorial 7: Using Nokia 5110 LCD

In Tutorial 4, we learnt interfacing an HD44780-based LCD to a chipKIT board for displaying alphanumeric output. Today, we will see how to connect a NOKIA 5110 graphical LCD (used in Nokia 5110 cell phones), which is a 84×48 pixel monochrome display of about 1.5″ diagonal in size. The display can be used for graphics, text, and bitmaps. [caption id="attachment_12138" align="alignnone" width="580"] chipKIT N ...

chipKIT Project 5: Digital stopwatch on seven segment LED display

In this project, we will use the chipKIT Uno32 board to build a digital stopwatch capable of timing minutes, seconds, and 1/10th of seconds, and with a basic start and stop control feature. A MAX7219-driven 8-digit seven segment LED display is used to display the time elapsed. The Reset switch on the Uno32 board will be used to reset the current time back to 0 when the stopwatch is stopped. [caption id="att ...

chipKIT Project 4: Digital light meter

A light meter is used to measure the intensity of illumination in a given area. It is widely used in schools, warehouses, factories, hospitals, office buildings, museums, art-galleries, parking garages, stadiums, and many more, to measure and maintain proper lighting levels. The intensity of illumination is usually expressed in Lux or foot-candles. As the 4th project in our chipKIT tutorial series, today we ...

Universal Driver & Dev Board using PIC16F

Description The simple 8 channel LED chaser has been a very popular project on Picprojects since it was first published a couple of years ago.  During that time there has been a demand for a board that could drive more LEDs so I started designing a new version of the LED Chaser using MOSFETs.  What I wanted to do was come up with a circuit design and PCB that while fulfilling the need for a MOSFET driver co ...

chipKIT Tutorial 1: Digital input and output

Our first chipKIT tutorial is about reading and writing digital data (0 or 1) from and to an I/O pin of the chipKIT board. Digital inputs are useful to determine whether an incoming digital signal is logic HIGH or logic LOW. A simple application of digital input is reading the state of a push-button switch and perform some action based on if the switch has been pressed or not. Similarly, digital outputs are ...

chipKIT Tutorial 2: Serial communication with PC

The PIC32 processor on the chipKIT Uno32 board provides two hardware serial ports. One of these is used by the on-board FTDI chip to create an USB-UART interface that allows the MPIDE tool running on the PC to communicate with the Uno32 board through an USB port. In this tutorial, we will use the same USB-UART interface to demonstrate a two-way asynchronous serial communication between the Uno32 and the PC. ...
