A frequency counter is a useful addition to an engineer’s toolbox and you can create the design described on this page for free. All you need is a PIC microcontroller (or any microcontroller that has a high speed timer input module) and a 2 line LCD display (the standard HD44780 one is the one used […]
This post provides the UART code (compiled in MPLAB + HI-TECH C) for PIC18F452 (e-g to connect PIC18F452 controller with PC using serial adapter). Complete project code and the proteus simulation can be downloaded from the Downloads section at the bottom of this post. The following diagram shows the required circuit. A crystal of 10MHz is used with PIC18F452. […]
Introduction We designed a device that can aid in learning the alphabet in American Sign Language. We built a glove with various sensors to identify the hand position of the user closely and use that to give feedback on what they are doing right or wrong through the LCD display for each letter in the […]
This post provides the PWM code (using C language) and Proteus simulation for PIC18F452 micro-controller CCP1 and CCP2 modules ( written using MPLAB and HI-TECH C18 compiler ). There are many uses for PWM signals, e-g you can control dc motor speed using PWM. CCP is the name for the built in PWM module in […]

You can download this code from the ‘Downloads‘ section at the bottom of this page. In this post, it is assumed that you know, How to use ADC of PIC12F675 microcontroller. If you […]
This post provides the PWM code for PIC12F675 microcontroller using timer0. There are many uses for PWM signal, e-g you can control dc motor speed using PWM. Timer0 is initialized in the start of the main function and using timer0 interrupts, PWM is generated. This code is written in C language using MPLAB with HI-TECH C compiler. You […]
Introduction We developed a wearable hydration monitoring system that will track an individual’s hydration levels by measuring the bioimpedance of the skin, that will transmit the data via Bluetooth to his or her cellphone, and that will provide a visual cue corresponding to their hydration. Our completed project! High Level Design Rationale Dehydration is usually […]
