Good things do come in small packages! Meet  Tah – the creation of India’s Revealing Hour. A super simple, bluetooth enabled device that connects directly to your smartphone and is compatible with the Arduino. There are several gizmos like this on the market but this one takes simplicity and integration with our smartphones to a new level. It is this utilisation of your smartphone crossed with the power of the Arduino platform, makes this a winning combination and one that can be utilised by so many of us.

What the Tah offers at a glance:

  • Arduino-compatible
  • Bluetooth Low Energy + Beacon
  • USB HID-compatible
  • iOS and Android Libraries
  • Open source throughout
  • ATmega32U4 microcontroller
  • Bluetooth 4.0
  • 32KB of flash storage (4KB reserved for the bootloader)
  • 6 analog I/O pins
  • 12 digital I/O pins (7 of which usable as PWM)
  • SPI and I2C peripherals
  • Range 10-100 ft

Setup couldn’t be easier. Simply power up the Tah by connecting it to any USB port on your computer or if you wish, a USB wall adapter. Of course, using a USB wall adapter opens up the additional possibilities of utilising the device in places where you don’t have access to a computer and for installations around the house that you wish to keep discreet.

Then download and install the Tah application from the iOS store and you are ready to start! I guess the question is now – what do you wan to control with your smartphone!?

There are currently 3 apps available for free via the iOS app store

Tah – which enables control over the various Pins on the Tah with speed and simplicity thanks to the no fuss design.

Tah Sensor – This comes with in-built setups for assigning the various Pins to various sensors with a super minimal, no fuss design.

Tah RGB – Use this app to change the lighting on a bunch of RGB LEDs. You can then use your phone to have the LEDs light up according to the colours of your choice or cycle through the selected colours in a rainbow mode.
I managed to connect a simple LED light to a pin on the Tah and simply turn it on and off using my smartphone within a matter of minutes. I just scanned for the Tah device using the Tah app and connect and then toggled the state of pin 13 to turn on/off the green the LED.

Next up I think I might try and make myself some kind of interactive christmas tree lighting using a ton of LED lights!

Early bird backers can grab one of these for $39 with more options at varied price ranges via the Crowdsupply website.
