Various topics of interest appear here to highlight project activity that is technical in nature. These posts are about subjects and accomplishments at a substantive and abstract level of learning or interest. From hardware, software, and systems to other areas of learning, there are subjects here concerning ongoing personal and professional interests.
Smoke Detector with Alarm and LED Indicators
While the MQ-2 gas sensor is one among a range of gas sensor types, it is roughly suitable for coarse experimentation for substances other than smoke. This sensor is sensitive ... Read More
Flame Detection with Sound Alert & Warning Light
An Arduino Nano is set up in this project to run a flame detection sensor as a small fire alarm system. The system uses a small active buzzer (muted) and ... Read More
Arduino Clone Bootloader Setup & Programming
Arduino modules (in this case an Arduino Nano 3.0) may come from China without the hardware initialized with a suitable bootloader. Necessary for project work and programming, a bootloader configuration ... Read More
DC Motor with Variable Speed Control by Joystick
This project makes use of a thumb joystick to control the direction of shaft rotation on a DC motor. The joystick also controls the rotational speed of the motor shaft ... Read More
Servo Motors with Two-Axis Joystick Control
This project makes use of two servos (Tiankongrc MG995), servo mounting brackets a 2-axis thumb joystick, an active buzzer, and an Arduino Uno R3. To operate the two servos together ... Read More
Stepper Motor with Direction Control & Reversal
This project involved a 5VDC stepper motor and its corresponding ULN2003 driver assembly. Stepper motors are unique from servos or DC motors because they are very precise, have a full ... Read More
Tilt Switch with LED Indicator and Fan Interrupt
This project was about making a tilt sense system that involves a motor or fan. The system is also programmed and set up with a tip sense light. It simulates ... Read More
Light Sensor Control of Servo with Photoresistor
This project makes use of a photoresistor as a light sensor to control the movement of a servo motor's shaft. The change of position in the servo motor's output shaft ... Read More
Color and Light Control via Infrared Sensor
This project runs with an IR sensor that reads a remote control's Hexadecimal data bursts as its buttons are selected. Each button represents a function that becomes executed programmatically within ... Read More
