Line Follower Robots are the most common type of robots that are built by hobbyist and student interested in robotics and embedded systems. The reason for the popularity of the Line Follower robot is the fact that is simple to build and easy to understand the logic behind it. This post will give you working […]
Introduction For our final project, our team built a touch screen controlled Etch-A-Sketch we call Touch-A-Sketch. The Touch-A-Sketch is the first of its kind that allows users to draw on the touchscreen and sketches the drawing on the Etch-A-Sketch by controlling the knobs on either corner of the toy. There are four main components that […]
After interfacing the DHT11 with Arduino uno board at the following post: ARDUINO Humidity & Temperature Measurement Using DHT11 Sensor Now we are going to see how to interface this sensor with microchip pic16f877a. There are some descriptions of how this sensor work in the above link A brief description of the code: The code […]
Description This project shows how to use a SD-Card with FAT16 file system. It is based on the example MMC/SD-Card driver (mmcsd.c) and FAT file system driver (fat.c) delivered with the CCS C compiler. Unfortunately, the example didn’t work properly for me. So I searched the web and found some required changes to make it […]
Overview A Pulse Width Modulation (PWM) output from a PIC microcontroller can be used to play tones on a piezo speaker. With this, musical scales and simple songs can be played on the piezo speaker. Piezoelectric speakers operate by the converse piezoelectric effect: when a voltage is applied across the terminals, the piezoelectric material in […]
Introduction This project was the first stage of developing a controller for a radiant floor heat system. The microcontroller will use inputs from thermostats, thermocouples, a flow meter, and pressure switches to control the operation of the pumps and valves to achieve improved efficiency of the system as a whole. This project idea came from […]
Introduction In this project, we demonstrate a real-time stock monitor that uses the popular ESP8266 Wi-Fi module controlled by a PIC32. We decided to build a fun device that fetches chosen stock prices in real-time and displays them on a screen. The goal was driven by a desire to create a PIC32 system that connects […]
Overview Secure Digital Cards, or SD cards, are used to hold information in many common electronic devices from digital cameras to mobile phones and come in sizes as small as 4 MB and as large as 8 GB. In this lab, we will establish communication between a Microchip PIC 18F4520 and a 2GB SD card […]
INTRODUCTION: The Switch Relay was designed to give clients control over two different switch-activated devices using only one switch. Pressing and releasing the switch will directly control the first device. However, when the client presses the switch for a minimum duration of time, the device toggles its state so that the switch now controls a […]
Rationale The project’s focus is to accurately simulate the movement of a human arm on a small-sized robotic arm, such as aiming and throwing small objects, i.e. a ping pong ball. We use motion-controlled, 3-DoF robotic arm that takes the user’s throwing motion as a reference to its own throw. A robotic arm that mimics […]
