ATmega32u4 MCU powers littleBits Arduino module



LittleBits has debuted a programmable ATmega32u4-powered Arduino at Heart Module. The new component will allow Makers to easily incorporate sketches into their littleBits circuits.

According to a LittleBits rep, the Arduino Module is capable of reading two types of input signals.

“The first is digital, which is a simple ‘on’ or ‘off’ signal. This is the type of signal you will get from a button or trigger. In the Arduino coding language, on is a HIGH signal and off is a LOW signal. All three inputs on the Arduino Module can read digital signals,” the rep explained.

“The other type of signal is an analog signal. Analog signals aren’t just ‘on’ or ‘off.’ They work like a dimmer switch or a volume knob. In the Arduino coding language, analog signals are given a value between 0 and 1023. If you connected a dimmer module to your Arduino and turn the knob up (clockwise), the value would slowly rise from 0 to 1023. The inputs on the Arduino module marked a0 and a1 both accept analog signals.”

As Engadget’s Jon Fingas notes, the programmable module gives Makers much more control over LittleBits’ existing modules, such as the oscillators in the Synth Kit.

“However, it also opens the door to interaction with your computer. Since the Arduino module has USB support built-in, you can create Etch-A-Sketches, Pong games and other programs that have LittleBits and your PC working in harmony,” said Fingas.

“[Plus], many existing Arduino projects should work with only a few slight tweaks to pin assignments.”

The stand-alone Arduino module can be snapped up for $36, although LittleBits is currently offering an $89 starter bundle that includes a total of 8 prototyping modules.
