Introduction We created a 3 rotational degree of freedom quadcopter frame. The result was so that when placed on the small surface area of roughly a finger tip, the quadcopter can maintain its stability and recover from perturbations. The four motors increase and decrease in speed according the size and direction of the disturbance so […]
This PIC project uses an I2C Real Time Clock IC (DS1307) and a four digit seven segment display to create a standard desk clock. Note: If you typed DS1703 Real Time Clock to find this page you probably mis-spelled the chip type. Anyway you can find a DS1307 (RTC) Real Time Clock IC project and information […]
In the same way as the LCD project this frequency counter circuit uses TMR1 in 16 bit counter mode to count the input signal edges. Counter overflows are accumulated to give the total count in multiples of 65536. Adding the current value of the counter at the end gives the total count. Specification of the […]
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 […]
This post provides the code to make an LED blink using PIC12F675 microcontroller. This code is written in C language using MPLAB with HI-TECH C compiler. This code is intended to be the first step in learning how to use PIC12F675 microcontroller in your projects. You can download this code from the ‘Downloads‘ section at […]
This post provides a simple digital voltmeter circuit using PIC12F675 microcontroller. This code is written in C language using MPLAB with HI-TECH C compiler. 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 […]
