Various projects concerning single board computers within the Arduino platform of technologies appear here to explore various types of applications or use-cases. Both hardware and software topics that apply to early and more recent iterations of the platform get further attention with posts here that indicate utility and functions have a meaningful purpose.
Proximity Detection with Distance Sensor HC-SR04
This project involves the use of an HC-SR04 proximity sensor commonly used among robotic devices for purposes of collision avoidance. In this project, the sensor is applied to an Arduino ... Read More
Portable Temperature & Humidity Monitor System
The purpose of this build is to become more familiar with how to develop a free-standing Arduino system using the Arduino Nano. The Nano is a smaller equivalent to the ... Read More
Liquid Crystal Display Setup, Control & Calculator
A common Arduino system typically includes a display of some type. This project was to set up a 16x2 LCD display to an Arduino unit and run it with simple ... Read More
Pushbutton Switch Dimmer Control & Alarm
This project controls an increasing and decreasing voltage level in increments to represent a dimmer present at an LED. An in-circuit buzzer serves as an alarm to indicate either a ... Read More
Toggle Switch PullUp with digitalRead
This project involves a toggle switch that an Arduino UNO recognizes through code as necessary to activate an LED over a GPIO pin. Assembly of the circuit requires a 330 ... Read More
Pushbutton Switch PullUp with digitalRead

Photoresistor Sensor Control of Buzzer Alarm
Using the point-slope formula between the on-time and off-time of a passive buzzer, we can control the high frequency and low-frequency tone sound as a function of light. As a ... Read More
Active Level Alarm with Trim Control via GPIO
This project sets up a continuously monitored voltage level change at a potentiometer as derived from a source reference. As continuously variable voltage level changes, voltage levels are read into ... Read More
Conditional IF Operation with Logic Parameters
To evaluate the function and purpose of an IF statement, a true or false, or comparative operation is performed for external circuit hardware to act upon conditions or an input ... Read More
