When piloting a vehicle remotely, it’s only natural to tilt your controller one way or the other to “help” guide it in the right direction. While usually this has no effect whatsoever, YouTuber Electronoobs decided to take this concept and run with it, creating a remote control transmitter that responds to an onboard MPU-6050 inertial measurement unit.
The transmitter’s Arduino Nano takes movement data, and sends the corresponding signals to a custom receiver board on the RC car via a pair of HC-12 wireless modules. A second Arduino mounted in the car then commands the vehicle’s DC motors with the help of an H-bridge.
This is a radio controller that has 2 analog channels and the data is out from a MPU-6050 gyro module. So, we could control a toy car for example just by rotating the controller. I usually use the nRF24 module, but in this project I also want to show you how to use the HC-12 module. You will learn how to get the IMU data, how to use the HC-12 radio connection and how to control 2 DC motors using PWM signals and an H-bridge.
It’s quite a versatile build, and it can even be set up to output PWM signals if you need to interface with more advanced electronics.

In the following 10-minute video, the Currah team is showing us all the details of Wood Lizzie, a project experimenting with Arduino Mega and Wi-Fi Shield, a very flexible steering system and the virtually unlimited control range afforded by WiFi and Internet Protocol:
The original plan was to construct one of the two-wheeled robots very popular with hobbyists but it was eventually decided that the resulting vehicle would be of very limited application and capable only of traversing smooth surfaces. However, note that the current design can be viewed as the drive of a two-wheeled robot coupled with a trailer by means of a 360 degree pivot. A slip ring capsule within the pivot enables the heavy battery and bulky control system to be separated from the drive and located on the trailer thereby distributing weight evenly between the four wheels.
DIY soap-carts were pretty common among kids in the first part of the 20th century and built from old pram wheels, scrap wood and, typically, soap boxes. They could provide a lot of fun for the family at very low cost and in recent years there’s a new interest in them especially to those appreciating their vintage look!
Toot is an interactive and sound-active toy designed for children aged between 3 and 6 years old that wants to enhance their auditory, music and language skills. It was developed by Federico Lameri as his thesis project of Master of Interaction Design at Supsi and prototyped using Arduino Leonardo.
The toy is composed by eight little cubical speaker boxes:
On each speaker children are able to record a sound. In order to listen back to the recorded sound the speaker must be shaken as if the sound was physically trapped into a box. After having recorded sounds on them, the speakers can be placed in a sequence after Mr.toot, and by tapping on his head it is possible to trigger the playback of the speakers in a sequence. toot is also matched with a mobile application that offers different kind of interactions and experiences. it allows to play some exercise that will teach children to listen, understand and catalog sound and melodies.
The app expands the possibilities of interaction, offering different exercises created with the help of musicians and educators from different areas of expertise, some of them are also inspired by a Montessori sensorial activity.
Take a look at the video interview with Montessori educator Fanny Bissa:
Artist Blair Neal, as many other great creators have before him, turned to children's toys as the source of inspiration for his latest project. Crayolascope is a rudimentary 3D display hacked together from several Glow Books, a light-up play on a flip-book from the titular company. The installation, currently housed at the New York Hall of Science in Flushing, layers 12 of its component clear plastic sheets to create a roughly one-foot deep display that plays a simple pre-drawn animation. The whole thing is controlled by an Arduino Mega, that can either play back the neon scribbles at varying speeds (controlled by a knob built into the console) or scrub through frame by frame. Neal isn't quite done tweaking the Crayolascope either. As it stands he's limited to between 14 and 18 frames, before it becomes too difficult to see through the sheets. And it requires near total darkness for optimal operation. To see it in action check out the video after the break.

The little drum playing robot designed by Steffest makes great music.
You control it like most drum computers: you draw the beats on a pattern of sixteen dots, perfectly suited for generic 4/4 rhythms.
There a 8 lines, each controlling 1 servo motor.
Most of the servo’s have a percussion item both on the left and the right, that’s why the pattern buttons have 3 states: off, left, right.
That makes 14 distinct percussion sounds for the drummerbot.
The pattern in the webbrowser is packed into a string, which get send to the Arduino via HTTP.
You can use a wifi module and a http server on the Arduino, or you can use another device attached to the Arduino through a comm port.
The Arduino receives the string, unpacks it back to a pattern and simple loops over the steps controlling each servo.
The Arduino code can be got from here. The music did make me smile!
