LED displays are commonly packaged as arrays of LEDs organized in rows with shared positive terminals and columns with shared negative terminals, or vice versa. Here is a standard illustration, along with its diagram: These exhibits can be very useful. To control a matrix, you connect its rows and columns to your microcontroller. The columns […]
Arduino Knight Rider light effect, a simple variation of blink code. Parts List; 1) 5x 5mm red LED 2) 1x Arduino 3) 5x 330Ω resistor 4) Jumper wire Instruction; 1) Connect all LED as diagram below, make sure cathode lead of LED at ground wire. 2) Connect all 330Ω resistor to anode lead of […]
This is just a brief run down on how easy it has become to make your own circuits complete with your own PCB’s. Have you ever wanted to make something custom that suits your needs? Of course you have!! For me it really started when I built my first day/night light. I used a light […]
Introduction For many electronics projects, AVR microcontrollers are commonly used. However, as a beginner, uploading or flashing code to an AVR can be challenging to understand. When other programming hardware is unavailable, an Arduino board can help burn bootloaders onto AVRs. It also enables creating and testing AVR programs. Therefore, this article will demonstrate using […]
This project is a part of experiments done while doing an artist in residence at Instructables. You can see the other projects here. Creating emergent patterns that can be converted into sounds fascinates me. So this is my first experiment in building an arduino platform for creating such patterns. This version uses a Gameduino as its […]
Arduino Based Real-Time Oscilloscope The Oscilloscope is an essential instrument for the workbench of every electronics engineer or maker. It is primarily used for monitoring waveforms and analyzing voltage levels, frequency, noise, and other signal characteristics that can change over time at its input. Embedded software developers utilize it for code debugging while technicians depend […]
This is a tutorial on how to use 123D Catch to get a 3D scan of your whole body. Once you have the scan or “catch” the tutorial will take you through a technique to clean it up and manipulate it ready for 123D Make. The tutorial will go through how to slice the model […]
There is always a need for automating a process,be it a simple/monstrous one.I got the idea to do this project from a simple challenge that i faced while finding methods to water/irrigate our small piece of land.The problem of no current supply lines and costly generators (to operate our pump) added to the difficulty. So […]
INTRODUCTION & OBJECTIVES: I am a basic system that utilizes Arduino for automating the watering of small potted plants or crops. This system monitors soil moisture levels by using LEDs for indications and emitting an alarm beep if the soil is dry. If the soil is dry, the irrigation system will be triggered to pump […]
My close friend, who works as a teacher, was conducting quizzes in her class that involved students competing to answer questions. This caused some students to complain about not getting a chance to answer even though they had raised their hands first. I chose to gift her with a buzzer similar to those used on […]
