Arduino Running A DC Motor and High Current Lamp
The BC547 transistor has a maximum operating current of 100 mA and a maximum voltage rating of 65 volts. When oriented with the label facing the viewer, the three terminals from left to right are collector, base, and emitter. It...
FYProject12
The objective of this experiment is to evaluate the range of the ultrasonic sensors (transmitter and receiver) utilized in this project. The sensor will be tested over a distance of 5 meters. The transmitter will be positioned directly facing the...
Wheelchair Obstacle Avoidance System
First, download any version of the Arduino software (the latest version is recommended) using the provided link, and then download the specified Arduino sketches. After the download is complete, open the sketches to view the written code. Complete the circuit...
led Arduino multiplexing help needed
To construct a 7 to 128 demultiplexer using 3-to-8 and 4-to-16 demultiplexers, the three highest bits of the output address should be fed into the 3-to-8 demultiplexer. The outputs from this demultiplexer will serve as the enable inputs for the...
Knock Block using an Arduino board
Humanity has long grappled with the concept of Time, often seeking ways to interact with it meaningfully. A proposed solution is a knocking platform designed to address these fundamental needs, exemplified by the Knock Block KUI and its associated Clock...
servo creating a switch using arduinos digital outputs
Charge a simple servo that only has + and - pins. Typically, the - pin is connected to ground, while the + pin is connected to a digital output from an Arduino. This setup works, but the servo operates weakly...
Modify an Arduino for DebugWIRE
This article discusses the Diecimila; however, there is a newer article that focuses on the Duemilanove. A shift in topic is presented, providing instructions on how to modify an Arduino board to enable useful functions such as debugging.
The Arduino...
Arduino While Loop
Sometimes, it is necessary for a program to halt execution while a specific condition remains true. This can be accomplished using a while loop. The following example illustrates the application of a while loop to calibrate the value of an...
Arduino UNO Tutorial NightLight
A Light Dependent Resistor (LDR) is utilized to create a simple nightlight for children's bedrooms that automatically turns on in darkness and off in light. The resistance of an LDR varies based on the light intensity it receives. In this...
