The Hummingbird by BirdBrain Technologies is an Arduino AtHeart microcontroller designed to enable beginners to create robots from craft materials. Hummingbird kits include LEDs, motors, and sensors that connect directly to the board. This eliminates the need for soldering or breadboarding and ensures that users have the parts they need to build their first robots. All of the components are reusable, so the same kit can be used to build many different robots.
In addition, the Hummingbird supports a variety of programming options, making it appropriate for beginning programmers as well as those who are more advanced. Some programming languages, such as Scratch and Snap!, can only be used when the board is connected to the computer. We will concentrate here on programming alternatives that enable users to upload a program onto the board’s Arduino.
This robust DIN rail mountable, Leonardo-compatible controller enables you to take your existing Arduino projects and swiftly transform them into permanent installations. The prototyping area and screw connectors allow you to install your own circuitry and reliably connect to accessories.
In the video below, Industruino co-founder Loic De Buck discusses these key features and more with Davide Gomba. (You can also find an extended version here.)
The team recently created an excellent tutorial showing how you to build an Arduino-based electricity consumption monitor with the Industruino PROTO platform. You can use it to measure AC power of your appliances, including a water cooker, TV, laptop charger, or anything else plugged into a wall socket. Alternatively, you can even use it in your electricity cabinet to evaluate the power consumption throughout your entire house (at least one phase).
The challenge is to measure an AC of a relatively high voltage (220-240V) with a direct current 5V Arduino MCU.
This may seem dangerous, but we will use a non-invasive Current Transformer (CT), so our Arduino remains galvanically isolated from the high voltage AC.
This prototype is based on the excellent open source project OpenEnergyMonitor. It uses parts of the its standard emonTx hardware and software to report the AC apparent power consumption, based on measurements of a Current Transformer as in the picture on the left. The original project also allows to measure 3 phase and/or real power, but for our prototype here we are only measuring the current of one phase, not its voltage which would require an AC/AC adaptor.
A few days ago, we launched the MKR2UNO Adapter, which enables you to easily turn an Arduino Uno form factor project into a MKR1000-based one. Simply mount your IoT board to the adapter, plug in any Uno shield and have a wireless device in no time.
Our newly-published tutorial provides a step-by-step overview of how to build a WiFi-controllable robot using the MKR2UNO Adapter with a MKR1000 and an Arduino Motor Shield.
This project combines the Arduino MKR1000’s web server and Arduino Motor Shield’s capabilities to drive a pair of different DC motors. A basic interface is hosted and hard-coded in the MKR1000, allowing the user to maneuver the robot up, down, left or right.
Starting a new project is always a fun yet effective way to hone your skills while exploring circuitry and programming. To help improve his engineering chops, Joop Brokking recently bought an inexpensive oscilloscope (a device for visualizing voltage over time in an x-y graph) and connected it to an Arduino Uno. He then shared his findings in a detailed tutorial on YouTube.
Last year, we announced on the blog how Windows became the first Arduino certified OS and introduced Windows Virtual Shields for Arduino and Windows Remote Arduino. Now, engineers at Windows have published a blog post showing how you can use Windows 10 IoT Core to create or port Arduino Wiring sketches that will run on supported IoT Core devices. (more…)
Increasing accuracy in the collection of data coming from sensors is a need that, sooner or later, Makers need to face. Paul Martinsen from MegunoLink created a tutorial to eliminate noise from sensor readings on Arduino with three simple filtering techniques.
The Averaging and Running Average techniques are easy to implement as they work by adding a number of measurements together, then dividing the total by the number of measurements. In both cases, the downside is that it can use a lot of memory. (more…)
If you’ve been looking for a simple audio Arduino project, you may want to check out this VU meter from YouTuber RZtronix. The Maker built the device using an Uno along with some LEDs, a couple wires, a breadboard, a sound sensor, and a 5V power supply.
Project-based lessons are a great way to introduce students to the world of electronics. Clearly Jenna Debois agrees, as she has built a DIY classroom clock based on an Arduino Nano. What’s even cooler is that it’s optimized for teachers! (more…)
