Block Diagram This diagram shows the basic components required for collecting temperature readings from seawater and transmitting the data to a base station where it can be collated into a database for analysis. To the left is a schematic of 10 temperature sensors, spaced 1 metre apart and immersed in seawater to a depth of […]

Modifying an Arduino Mega and chipKIT Max32 for 5V Operation
Max’s Arduino Mega and chipKIT Max32 both require 9V external supplies, but he really wishes to power them from a single 5V supply. Well, nothing is simple, is it? I ran into a minor “gotcha” with regard to my Bodacious Acoustic Diagnostic Astoundingly Superior Spectromatic (BADASS) display project. As you may recall from my previous […]
Arduino Projects: Wireless Arduino
Long-time readers will know I’m not one to promote trendy marketing phrases and certainly ‘Internet of Things’ or ‘IoT’ is right up there with the best (worst) of them. But the concept behind the phrase is worth understanding as it drives the next generation of connected devices. Single-function or ‘embedded’ gadgets built from microcontrollers like […]
Making a RFID Card Reader with Arduino Yún
Surya Mattu is a creative technologist who loves to make things. He’s based in NYC and working at ITP, a two-year graduate program exploring the imaginative use of communications technologies. Today he’s sharing with us how feasible it could be to build an RFID-controlled entry for students using Arduino Yún. Read other guest posts on Arduino Yún. […]
Arduino Project 6: Web-controlled music player
Our NetPlay project is built on a standard breadboard. In our previous Arduino masterclass we briefly introduced the Ethernet Shield an Arduino expansion board that adds Ethernet connectivity plus microSD card storage. We used that storage as the basis of a simple one-button digital audio player. It was functional but limited to 8-bit mono WAV […]
Simulating and controlling GE Color Effects Lights with Arduino
Overview This project builds a Christmas lights controller for the GE Color Effects lights allowing programmed control of up to 8 sets of Christmas lights. Furthermore, it provides a function specific language for programming patterns for these lights and an emulation environment for testing the programs requiring the lights to be built or hung. Pre-reading […]
Arduino Project 8: Stompy the robot (part 1)
Our first Arduino robot called Rolly in our February issue proved to be a popular project. Powered by an Arduino Uno board it was easy to put together and cost very little. In this project we upped the ante again with our first walking robot appropriately called Stompy. He’s a quadruped a four-legged walker and […]
Tutorial: Arduino Motor/Stepper/Servo Shield – Part 1: Servos
This post starts a small (or larger?) series of tutorials using the Arduino Motor/Stepper/Servo Shield with the FRDM-KL25Z board. That motor shield is probably one of the most versatile on the market, and features 2 servo and 4 motor connectors for DC or stepper motors. That makes it a great shield for any robotic project […]
Communication between a USB/serial device and an AVR (atmega/Arduino) microcontroller
I have a device which provides a USB port. If I attach it to a Windows PC it is recognized as a “CP2103 USB to UART Bridge Controller”. According to the device documentation, it should communicate in serial format at 38400bps.I have to talk to this device with a atmega microcontroller. Since the USB pinout […]
Store Arduino data to Firebase database [Howto]
The last few weeks I was playing with Firebase mostly because I wanted to get familiar with this technology. So at some point I thought that it will be a great idea to connect Arduino with Firebase. Imagine that you have a simple temperature sensor that measures the boiler’s water temperature every few minutes and […]
