How to Control NeoPixel Installations via Wi-Fi Using Fishino and NodeMCU with Python
We create NeoPixel light installations with Fishino and NodeMCU controlled via Wi-Fi from a PC or Raspberry Pi using a Python library. A few years ago, the American company Adafruit Industries transformed the LED market by introducing NeoPixels, RGB LEDs that incorporate their own controller in a single package. Adafruit aimed to simplify LED management…

Wifi clock with Bluetooth speaker and spectrum analyzer
In this project we see how to make a Bluetooth speaker with a clock. It displays date, time, temperature and humidity and it is updated from Internet at 15 minute intervals. It also has a 32-band audio spectrum analyzer that displays different musical patterns. The clock or spectrum analyzer can be displayed while playing music….

I2C car with Attiny85 and M5StickC controlled by Blynk
In this project we see how to create an I2C system to control motors using a DigiSpark Attiny85 plus an Arduino shield. To test its operation we made a small RC car that uses an M5StickC and connects to the Blynk app to communicate via the I2C protocol. We used two communications in this project…

Jolly: add WiFi to your Arduino UNO
With 10 million Arduino UNO sold worldwide, this board becomes the most widespread prototyping board ever. The first Arduino UNO board was introduced in 2005 and in those days integrating a communication system such as WiFi was extremely expensive. So why not think of something that would allow all owners of this board to make an…

Creating an online robot fighting game using Arduino MKR1000 WiFi
We introduced this concept last year, and have launched three games so far. Our final game of 2019 was SumoBots Battle Royale — where players from anywhere in the world can fight real robots in a battle royale-style arena. The aim of the project was to have the game run semi-autonomously, meaning that the…
