Grove - I2C Hub (6 Port) is an I2C expansion interface board, compared with the old Grove - I2C Hub, the same size, two more connectors, almost half the price!

Overview

We've already released the Grove - I2C Hub (4 Port), now comes the 6 port version, the same size, two more connectors, almost half the price!
As you may know, the 7 address length I2C bus allows up to 128 I2C devices to access.
At present, there are over 80 Grove I2C modules in Seeed, however, normally only 1 or 2 Grove I2C connectors are available on the Seeeduino Board or the Grove Base Shield. What if we need to use multi Grove I2C modules in the system? The answer is Grove - I2C Hub (6 Port).

There are 6 Grove connectors in this hub, one input, five output, or you can even connect one hub with another, so that more devices can be plugged in.
Not only I2C but also can be used to control several synchronous change devices (like LEDs).
We did a survey and gathered some feedback about the old Grove I2C Hub (4 Port), many users mentioned that the 4 slots are not sufficient, so we add two more and keep the same 20*40mm size.

SeeedStudio always values the voice of our customers, and we appreciate our customers helping us grow and make us better.

Controlling a drum machine with the Arduino Opta
Controlling a drum machine with the Arduino Opta
June 25, 2024

Makers have long asked the question “why bother with an expensive PLC when I can just use an Arduino?” The answer comes down to the priorities and needs of industrial clients. In a factory automation setting, the client will prioritize durability, reliability, and serviceability over the one-time purchase price of the device itself. But to prove that Arduino’s professional turnkey solutions are just as easy to use as their developer-focused educational counterparts, Jeremy Cook leveraged an Arduino Opta micro PLC to build a drum machine. This isn’t any old drum machine that plays sound samples or synthesized notes, but rather a robotic drum machine that makes noise by banging on stuff like a true percussion instrument. Cook could have built this with any Arduino board and a few relays, but instead chose to implement the Opta and new Opta Digital Expansion. That is robust enough for serious commercial and industrial applications, but is still simple to program with the familiar Arduino IDE. Programmers can also use conventional PLC languages if they prefer. In this case, Cook made noise with relays and solenoids. The Opta has four built-in relays and Cook’s sketch flips one of them to make a sound analogous to a hi-hat. Cook added an Arduino Pro Opta Ext D1608S module with its solid-state relays for the other two “drums.” One of those fires a solenoid that taps a small hand drum (the kick drum sound), while the other controls a solenoid that hits a power supply enclosure (the snare sound). Together, those three sounds can cover the basics of a drum track. Cook’s sketch is a drum sequencer program that stores each sound sequence as array, looping through them until turned off.  An Opta may be overkill for a project like this one, but this does a great job of demonstrating the ease at which an Arduino user can transition to professional PLC work.
