LED Blinking Sequence using PIC Microcontroller

LED Blinking Sequence using PIC Microcontroller EMBEDDED By Aswinth Raj   Dec 24, 2016 5 LED Blinking Sequence using PIC Microcontroller (PIC16F877A) In our previous tutorial, we learnt about  Blinking a LED using PIC microcontroller  and built the same circuit on Perf board. Then we used  PICkit 3, ICSP and MPLAB IPE  for dumping the program onto our Perf board. Now, in this tutorial we will advance our self to using more pins on the PIC microcontroller. We will use 7 outputs (LEDs) and one Input. For this tutorial we will use the old Perf board (shown below) and will add berg sticks to pull out the required pins onto the second LED board. At the end of this tutorial we will  Generate a Sequence of Blinking LEDs using PIC microcontroller  and will learn how to use multiple inputs and outputs, some basics on ‘for’ loop and function calling.   The LED board is nothing but another perf board, on which we will solder the ...

Robotic Arm Control using PIC Microcontroller

Robotic Arm Control using PIC Microcontroller EMBEDDED By Aswinth Raj   Jan 29, 2019 0 Robotic Arm Control using PIC Microcontroller From the assembly line of automobile manufacturing industries to the telesurgery robots in space, Robotic Arms are to be found everywhere. The mechanisms of these robots are similar to a human which can be programmed for similar function and increased capabilities. They can be used to perform repeated actions faster and accurate than humans or can be used in harsh environments without risking human life. We have already built a  Record and Play Robotic Arm using Arduino  which could be trained to do a particular task and made to repeat forever. In this tutorial we will use the industry standard  PIC16F877A 8-bit Microcontroller to control the same robotic arm with potentiometers.  The challenge with this project is that PIC16F877A has only two PWN capable pins, but we need to control about 5 servo motors ...

8 Channel Quiz Buzzer Circuit using Microcontroller

รูปภาพ
8 Channel Quiz Buzzer Circuit using Microcontroller In this project, I’ll show you the design and working of an 8 Channel Quiz Buzzer Circuit using Microcontroller (8051), which tells us which team has pressed the button first in a quiz or game show.  Quiz buzzers are used often at places like educational institutions and game shows, where it is required for the organizers to know who pressed the button first. Conventional systems require human intervention to decide which team has pressed the button and this system can be erroneous and even biased. Another problem arises when two members pressed the button at a negligible interval and it is difficult to guess who has pressed the buzzer first. Here in this project, I designed an Automatic Quiz Buzzer System in which, when more than one team presses the buzzer, the delay between the two button presses is accurately taken into account and the corresponding number is displayed. I have designed t...
