Note : This hack is only needed if your usb-serial does not support the BREAK functionality. Else, it may work with as it is, with the usual programming software like PicPgm, WinPic etc. Usually the DIY programmers like JDM do not work for usb-serial converters. Voltage levels, timings, and missing functionality like setbreak() causes issues. […]
This project is for the design and use of a PIC development tool which is flexible to suit a wide range of PIC based electronic projects. It is often easier to develop microcontroller projects with the use of development tools; which allow user based code to be demonstrated in real time. However, from personal experience, […]
The project is based on a Gsm/Gps/Gprs. Its main function is to detect a illegal entry and communicate its own geographical position using, on the choice, the cellular phone reference system or the GPS. I use the recent product by SIMCOM – SIM908 which operate on 5 – 12 volt dc supply, which makes it […]
Somewhat similar to PIC 12f675 mini protoboard, but extended and with additional boards.Using attiny2313. Step 1: Scheme Let us first start with a scheme. The scheme is pretty obvious since it only connects attiny2313 with the pins and the only additional elements are resistors and capacitor for reseting the microcontroller.

This project started off being based on an Arduino UNO. And it worded ok, I found the software published on the internet. For example https://forum.arduino.cc/t/model-railroad-speedome… This is actually version 2 using a smaller PCB and PIC chip. It works in exactly the same way as V1. I wanted to make the device smaller, neater and if […]
This is a post about the POV ( Persistence of Vision ) Display that uses one 7 Segment display. In short, I made this little project as a proof of concept of something I ‘ve always noticed in many electronic devices those used 7 segment display. Devices like 7 segment display clocks and meters. In those devices, the 7 segment […]
So I needed a DAC (digital to analog converter) to use with my pic12F675 , and for those of you who have never heard of this little fella, it’s an 8 pin microcontroller from Microchip that has only 6 I/O pins… This is a very simple circuit that converts Digital data (serial input) to Analog […]
Hello, guys! In this project I will try to explain my experiments on PIC MCU and Python serial communication. Over the internet, there are many tutorials and videos on how to communicate with PIC MCU over virtual terminal which is very useful. However, in my main project one of the requirements is to establish serial […]
PIC16F877A Pin out & Descriptions There are 5 ports that provide parallel I/O Interfaces to outside world PORTA, PORTB, PORTC, PORTD, PORTE Each port provides 8 bidirectional digital I/O lines which are connected to PIC16F877A pins provided that alternate functions are not selected on that Port. Eventhough Bidirectional at nay time the I/O line can […]
The inverter PCB is easy to assemble by following the label of the components to be inserted. The choice of the voltage to be used to power the inverter ranging from 12v to 48v depends on kva you are designing. for any setup, a 12v relay is to be use. The featuring M.C.U are the […]
