here is our our first tutorial on Instructable so be indulgent. This tutorial shows the method of using an Arduino UNO board as a PIC microcontroller programmer. This method has been tested with PIC 18F2550 and 18f4550 but can be used to program the following pic: 18F2420 18F2455 18F2520 18F2550 18F4420 18F4455 18F4520 18F4550 The […]

A PICBasic program which interrupts the PIC when a high/low transition occurs on pin PortB.0 The code is available for download as a .rar or just copy and paste it from here. I got the starting code from the microengineering website:http://www.melabs.com/resources/samples.htm but I added the register bit definitions and changed a little to make it […]

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.

I could not find a good name for this project. You could also call it an ‘enough sleep timer’. The idea for this project came up during a vacation in winter. We were in a vacation home where there was no alarm clock in the bed room. I normally need 8 hours of sleep but […]

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 […]
