For the transmitter, he turned an Arduino Pro Micro into a USB sound card which he could plug into his laptop. That outputs both the audio signal and a 40 kHz carrier signal, implemented using the ...

The transmitter Arduino breaks down a given string into individual characters, and then further converts the ASCII to eight binary bits. These bits are sent out as tones, and are picked up on the ...

A few months past and I gained some interest in making this OLED work. Therefore, I started to do some research. I found a library that supports all sorts of displays for Arduino, and it supports ...

In this mode, you place the Ultrasonic Experiment set facing an object up to 200cm away, and press the “SEL” button to take a sample of the distance. Once the sample has been acquired, the LCD ...

Do you desire a teeny, tiny, little Arduino board with OLED display? You bet you do! Microview is a new "chip-sized" Arduino on Kickstarter that costs $45. What can it do? All kinds of stuff!

This one is an unusual smart home project, potentially - how to monitor a fish tank’s health with an AI-enabled ultrasonic sensor system. The detailed project is highlighted on Hackser.io and features ...

Arduino is little open source circuit board that lets you create some fairly compelling projects with a few lines of code and some circuit boards. The latest addition to the project is LiquidWare ...

A pledge of just $45 gets you a single Micro-View with OLED Display, while $55 lands you the MicroView plus USB Programmer. $95 lands you the MicroView, USB Programmer, Learning Kit, and a Cross ...
