In this guide I will explain how to use a Windows 8.1 phone, Arduino Uno board, and HC-05 Bluetooth module to build a wireless oscilloscope. The phone application has the critical functions of an oscilloscope, although the bandwidth is a measly 300 Hz. Still, if you want to see squiggly lines on your phone, it […]

Context and Preparation Getting started with tinkering on Microcontrollers can often be hindered by the need to purchase hardware. In this tutorial, we offer an introduction to Arduino that requires no prior experience and no physical hardware. Instead, we will utilize an Arduino simulator called TinkerCAD. However, for those who do have the hardware, we […]

Ideation and Design: Microcontroller Morse Code System development initially aimed to create a functional Microcontroller Fidget Keyboard System by linking mechanical switches to a microcontroller. This section explains how the system captures and interprets button presses to convert user input into Morse code. This led to an early pivot in design, driven by practical challenges […]

The Arduino Mega serves as the system’s central controller in a project focused on Waste Management Using Arduino, managing communication with the load cell, RFID, SD card, and GSM/GPS modules via synchronous and asynchronous serial communication. It enables data acquisition, storage, and remote tracking, while LEDs provide user feedback and USB aids in debugging. Powered […]

The core objective of the project is to develop a Self-Stabilizing Parkinson’s Eating Aid—an auto-configuring device designed to prevent food spillage. The primary use case focuses on patients with Parkinson’s Disease (PD). The device’s function is to mitigate the unwanted tremors that many PD patients experience, providing a viable solution to a challenging situation faced […]

Homebot Within the integration unit, core systems—power, control, and prototyping of the robot—are being converged as part of the Arduino Homebot Robot Setup. Short, flat jumpers improve breadboard wiring by keeping connections secure, tidy, and less prone to short circuits. Laying components like resistors and LEDs flat boosts durability and creates a more reliable, low-maintenance […]

Arduino XMAS Hitcounter Christmas is coming closer, so here is my contribution to put you in the right mood. It is a blog hitcounter, that rings a bell. Literally. It puts a smile on your face, every time someone hits your blog. It consists of an Arduino board, a bell, a servo and a couple […]

This project shows how to send SMS text messages to a cheap scrolling LED display via an Android app and arduino with USB host shield. The project was originally inspired by a friend wanting to make a “sexting themed” costume, with a scrolling LED display of live texts sent from people at the party. We […]

Havahart traps are really nice if you have pests to rid your home of but you don’t feel the need to do this through means of killing the animal. The problem we are faced with is constant monitoring of the trap. If you forget to check back frequently (usually at least once a day), you […]

This Instructable will tell you how to use the IR (infrared) library on an Attiny. I will be using an Attiny85 with an Arduino Uno. I won’t cover how to upload sketches to the Attiny just how to use the IR library with it. the best tutorial on uploading sketches I’ve found is this YouTube […]
