WHAT IS PWM? PWM STANDS FOR PULSE WIDTH MODULATION is a technique by which width of the pulse is varied. To understand this concept clearly consider a clock pulse or any square wave signal it has 50% duty cycle that means Ton and Toff period is same, The total duration for which the signal was high and […]

This instructable covers the interface of 8051 microcontroller with the cheap 315/433MHz RF module. This comes in handy in different kinds of wireless connectivity projects like Robotics, Wireless Level sensors, etc. The sensor is really cheap, typically about $5. I have implemented this module with other controllers such as Arduino and Pic, but the 8051 […]

Hello reader. This is one of the most basic and important instruction ever made for Microcontrollers low level programming. Talking about the external interrupts routine in Assembly Language for PIC. Today I’ll present a blueprint for the development of an experimental basic circuit and show you the coding to learn how to use this simple […]

For some of my PIC projects I need a serial (RS232) interface to print some messages on the screen of my computer. I still have a desktop computer that has one RS232 interface but nowadays most computers have a USB interface instead. You can buy devices that convert – TTL – RS232 signals to USB […]

All you AVR user fraternity out there, and those just entering the stream, Some of you started with PIC microcontrollers and some started with ATMEL AVRs, this is written for you ! So you bought a USBASP because its cheap and effective to flash the ROM on your Atmega device, or maybe the ATTINY range. […]

The present project called PLC with Pic CI16F877A is based on the operation of a PLC, today we can see these systems in industries, mining, etc. It is used to program an industrial PLC, it is the ladder language or (LADDER). The project has the advantage of loading the program directly through the pickit3 so […]

A Message from me: Hello! Thank you for reading my first instructables on building a pulse analyzer using PIC24f in Assembly language. I have almost completed the project, but not yet finished writing this instructables as I want it to be as comprehensive as possible. It will take me another week to finish writing. Please […]

Although there are MANY good circuits available on the internet for similar projects, I had a dedicated problem to solve. Most of the circuits available switches their outputs on at mid stick position (50%). My drones all use six channels (Throttle, Aileron, Rudder, Elevator, GPS Mode, Flight Mode), thus not leaving any spare channel to […]

This Instructable is a beginners guide to debugging code programed in the MPLAB X IDE v2.0. The steps covered are common application’s of the debugger software and problems I encountered as a beginner user and a inexperienced programmer. The content will be useful to programmers with little experience using a microprocessor and writing code. More […]

This little project is an example of a simple audio application using a PIC micro-controller. We decided to use the PIC18F4550 micro-controller for memory purposes. Using only digital inputs and outputs, we developed this simple piano/synthesizer with an 8 bit kind of style: Inputs from b1 to b11 are the push buttons in the circuit while […]
