It is a revised version of my previous PIC-based relay timer project with added features and some improvements in the circuit design part. A while ago, I designed a development board for this MCU and I thought it would be worth sharing this design here.
This project is about a similar LED dice but with a slightly different output form. It uses 6 LEDs which are arranged in a circular pattern and are labeled 1 through 6. They create a chasing effect when the dice is rolled. The chasing effect slows down gradually, and eventually stops at one of the six LEDs. The rolling is done by a gentle shaking of the dice horizontally. My two and a half year old son loves toys with flashing lights.
This project describes a mono-color LED matrix display board consisting of LEDs arranged in 8 rows and 40 columns. Pages: 1 2 3. Continue ReadingThis microcontroller is popular among hobbyists and engineers due its features and cost. The description for each of these pins is given below.
PIC16F is a microcontroller good for experimenting and developing applications because it has high flash memory rewrite cycle. Also there are a lot of tutorials and support available online. The controller has 16KBytes flash memory which is enough for many applications. With Watchdog timer to reset under error automatically the controller can be used to develop applications of permanent installation. Like any other microcontroller, PIC16F needed to be programmed before getting the chip working.
Once power is provided, the controller executes this code saved in FLASH memory to create the response. After connecting the power, the controller executes this HEX code saved in the memory which is written program and creates response as instructed.

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 PIC16FA 8-bit Microcontroller to control the same robotic arm with potentiometers. Now, of course we could upgrade to a better microcontroller or use a de-multiplexer IC to make things a lot easier here.
But still, it is worth giving this project a try for the learning experience. The mechanical structure of the robotic arm that I am using in this project was completely 3D printed for my previous project; you can find the complete design files and assembling procedure here. Alternatively, if you do not have a 3D printer you can also build a simple Robotic Arm using cardboards as show in the link. Assuming that you have somehow got hold of your robotic Arm lets proceed into the project.
The schematics was drawn using EasyEDA. The circuit diagram is pretty simple; the complete project is powered by the 12V adapter. The reason for having two regulators is that when the servo rotates it pulls in a lot of current which creates a voltage drop.
This will display the duty cycle of the servo motors that are being controlled. Apart from this I have also extended connections for all GPIO and analog pins, just in case if any sensors need to be interfaced in future.
We have already tired something similar using the Timer interrupt method and were successful. Here we are just going to build on top of it, so if you are new here, I would strongly recommend you to read this previous tutorial before proceeding further. All hobby servo motors work with a frequency of 50Hz. Of this complete 20ms the control signal is only from 0 to 2ms while the rest of the signal is always off.
The below figure shows how the ON time varies only from 0 to 2ms to rotate the motor from 0 degree to degree of the total 20ms duration. With this in mind we have to write the program in such a way that the PIC reads in 0 to from the potentiometer and maps it to 0 to which will be the duty cycle of the servo motor.
Using this duty cycle we can calculate the ON time of the servo motor. Then we can initialize the timer interrupt to overflow at a regular interval such that it acts similar to the millis function in Arduino. With that, we can toggle the status GPIO pin to be high for a desired duration and turn it off after 20ms one complete cycle and then repeat the same process.
Now, that we have understood the logic let us get into the program. In this section we will discuss the logic behind the program. The below explanation is given assuming that the reader is familiar with these concepts. The most important section in the code is setting the Timer 0 to over flow for every specific delay. The formulae to calculate this delay can be given as. The crystal frequency Fosc used in our hardware is 20Mhz.
With these values the delay can be calculated as. So now we have set the timer to overflow at every 0. The code to do the same is given below. Of the total 0ms to 2ms control window of the servo motor we can control it with a resolution of 0. You can decrease this value further if your MCU could support it to obtain more positions and precise control. Now that we have the Timer 0 set to over flow for every 0. So inside the ISR function we can reset that flag and increment a variable called count by one.This guide hopefully will show you how to write C code that will allow you to read in an analog input AI value to your PIC microcontroller.
The microcontroller is a PIC, but the ideas discussed in this article will be applicable to many other PICs as well. Download it here if you don't have it already. Plugin Setup details found here. Assuming you are using a PICkit programmer, you then have the option to power the microcontroller from it. You may use this software and any derivatives exclusively with Microchip products. I will be configuring pin RA0 since that is the pin wired to the potentiometer on my board.
A bit value of 0 means it is configured as an output and a value of 1 indicates input.
Introduction to PIC16F88
Thanks for posting the great PIC tutorial. I have been meaning to get into PIC project but I have just been lazy and haven't done it. By kdjohnson Follow. More by the author:. Right click the project and select properties Select your PICkit programmer on the left hand side Select Power from the the dropdown menu check the power circuit from PICkit x box and set the voltage level to 3.
File Name: main. Set your clocksource essentially the ADC works by tracking how long a capacitor takes to charge. You can set how long it takes to measure it by changing your clocksource. Depending on your clock speed, setting it too fast can result in the capacitor not charging fully, so be careful Setting your negative and positive voltage references we are just using Vss and Vdd.
