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 […]

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

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
PIC32 ICSP Programmer v1.0 is based on a simple PIC32MX270F256B microcontroller basic circuit. It connects to a PC via USB 2.0 port and therefore needs no external power supply. It may be used to program a PIC32 microcontroller on a circuit via ICSP interface or you may add a programming header. It basically works similar

In this article, we will show how to drive a 7 segment LED Display using a PIC16F690 microcontroller. This PIC16F690 microcontroller chip is actually a part of the PIC2 Starter Kit, so we will actually be using this starter kit to drive the LED Display. A 7 Segment LED Display is an electronic device that

Introduction Virtually all PIC microcontrollers have some banking mechanism to extend addressing to additional memory space. But this external data memory is not directly addressable (except in some high versions of PIC18 devices, which include PIC18F8520, PIC18F6620, etc.). In this post we describe easy to implement external memory interface for PIC microcontrollers. Theoretically most of

In a previous article I described how I designed the circuitry to control functions of the asparagus harvester. After bread boarding up a test circuit and doing some initial programming I decided a re-do was in order. I found I had a lot of unnecessary redundancy and I also decided to put the air regulation
Introduction I always thought the clapper so cool. For those who are lazy like me, turn on or off the bedroom light without getting out of bed, simple clap your hands is amazing. Thinking about it I projected one for me. Several projects of clappers can be found on the Internet, and most of them

Abstract: A circuit and program listing for using the MAX6955 LED display driver with a PIC microcontroller and 14-segment displays. The MAX6955 is an LED display driver with an I2C™-compatible, serial interface capable of supporting Fast Mode speeds up to 400kHz. It is capable of driving sixteen 7-segment, eight 14-segment, eight 16-segment or 128 separate LEDs.
