I’m completely new to the world of PIC Microcontrollers and electrical engineering so please go easy Anyway, I managed to program my PIC 16f627 to turn on three LEDs when push button (trigger button) is pressed and start a shut down sequence (basically each LED toggles off one after another with a 5 second delay […]
WEBSD This is a development board for the PIC24F series of microchip, with: USB ( plug it to any computer) Ethernet ( plug it to the internet) SD card ( save and read all data you will need) I developed this thing as a learning platform, it worked ( still is). So if you always want to go […]
As per the title of this question i’m trying to control an ac resistive load. So far i had little success and i’m experiencing “strange”, to me at least, behaviour from the triac(s) i tried. first of all i post a schematic of my test circuit (bare with it, it’s not a complete schematic, it […]
This post provides the LCD[1] interfacing code using PIC12F675 microcontroller. This code is written in C language using MPLAB with HI-TECH C compiler. You can download this code from the ‘Downloads‘ section at the bottom of this page. It is assumed that you know how to make an LED blink with PIC12F675 microcontroller. If you don’t […]
A small PCB allows for the out-of-circuit programming of 18 & 28 pin SOIC PIC Microcontrollers from either an ICSP programmer or ZIF socket. A recent article in a popular electronics magazine presented a small printed circuit board for programming 18-pin SOIC PICs from a ZIF socket. Looking at the design I knew instinctively that […]
10-minute sewable iPod remote There are a lot of really cool iPod remote control projects: some have simple buttons, some react to heartbeat or body motion, and others are designed to interface directly with software running on a computer. However, not one of them is truly wearable, or speaks to the unique needs of e-textiles designers. […]
The PIC32 single-board computer is a de facto standard tool for developing microcomputer applications within the hobbyist and educational communities. It provides an open-source hardware (OSH) environment based on a simple microcontroller board, as well as an open-source (OS) development environment for writing software for the board. Here’s an approach that enables PIC32 code to […]
Introduction HD44780 based character LCDs require at least 6 I/O lines from microcontroller to display data. Therefore, they are not suitable for low-pin microcontrollers like PIC12F series microchips. In this project, I am going to show how to drive an HD44780 based LCD display with only 3 pins of a microcontroller. I am going to […]
This post would provide a working example of how to make a simple Current Meter (DCM) using 16bit PIC microcontroller and a series shunt resistance. We have very precise ammeter current measurement with a 10bit ADC and with a tolerance of ±10mA. You may download code and Proteus Simulation from the download section at the […]
In some of our projects, we may want to measure the distance of an object from a point. Ultrasonic Distance Sensors are the best sensor which provides stable, accurate, precise, non-contact distance measurements from 2cm to 4m. Ultrasonic Sensors can be used to measure distance between moving or stationary objects. Being very accurate and stable, these devices […]
