Introduction The Happy Little Mixer is an automatic ink mixer which accepts a hex user input and creates that color by measuring out cyan, magenta, yellow, and black (CMYK) ink. It includes open-loop feedback using a color sensor to correct the generated color, making it as accurate as possible. High Level Design We wanted to […]

Introduction For our final project, we built a system to aid in practicing kendo sword strikes by providing feedback to a kendo practitioner for improving their form. A set of three piezoelectric sensors on a helmet were used to detect the location and strength of the strike. Thus, the set of piezoelectric sensors would help

Introduction A digital thermometer is a good choice of project for beginners who just stepped in to the world of microcontrollers because it provides an opportunity to learn using sensors to measure the real world signals that are analog in nature. This article describes a similar project based on a PIC16F688 microcontroller and an LM35

INTRODUCTION AirBass is an air bass guitar that allows the user to play distinct notes without the added weight and cost of an actual bass guitar. It implements various sensors for input to output sound that is accurate both in terms of frequency and duration. HIGH-LEVEL OVERVIEW SOCIAL IMPACT Our plan for this project was
Measurement and control of temperature and relative humidity finds applications in numerous areas. These days devices are available which have both temperature and humidity sensors with signal conditioning, ADC, calibration and communication interface all built inside them. The use of such smart sensors greatly simplify the design and reduces the overall cost. We discussed in
This is a test project built hastily on a solder less breadboard. It uses a LM75 to read the current temperature via I2C and displays the result on three 7 segment displays. It uses a PIC16F628 with an internal 4 Mhz clock. The program was created using JAL Note the LM75 is a surface mount

Introduction In this project, we built a writing machine using a 4-DOF robot arm. This robot arm is controlled by PIC32 and can write the 26 letters and ten numbers. Users can send instructions to the microcontroller through the serial interface to control the robot arm to write words or digits they want. What we
Introduction For our final project, we built a 2 axis robot arm with a capacitive sensor on the final member, which will allow the robot to detect a person near the robot. When there is an object detected, the arm will stop depending on the measured capacitance. The purpose of this type of sensor is

Introduction For our final project, we created a spy robot: a robot that uses remote radar sensing to detect intruders. The physical system consisted of the servo setup we had from lab 4, a time-of-flight distance sensor (discussed in depth below), and the PIC32 microcontroller. The distance sensor was affixed to the servo setup and

Introduction Our project is a tilt maze game controlled by a glove worn by the user, which contains an accelerometer as well as sensors for each finger. The tilt of the maze is continuously updated in accordance with the position of the user’s hand. The maze itself contains several holes with servo-controlled trapdoors obstructing the
