Littlebits Arduino Coding Kit

Development Tools IDE 1.x

I just purchased "Littlebits Arduino Coding Kit" thinking that it was designed to interface with Arduino, but it seems that has its own Arduino Leonardo (although it doesn't look like one). I tried some simple programs trying to light an LED on the bargraph. I was able to light some of the bars but not turn them off. Also the Serial.println doesn't seem to work. My Arduino Uno works well and does what I expect it to do but the Littlebits one has got me baffled. I know that the Littlebits Arduino is not a typical Arduino but I don't know what to expect from it. So my questions are: (1) is it supposed to have Serial IO like other Arduinos? and (2) how to you turn on and off bars on the bargraph? The bargraph example code that I used was taken from examples available from the IDE menu and may not be what Littlebits expects.

Thanks in advance.

  1. Yes the littleBits Arduino (at Heart) module does serial IO just fine. It works exactly like any other Arduino compatible. Try this: Attach a pot to pin A0, and load the sketch from the Examples menu of the IDE, called AnalogReadSerial.ino onto the littleBits Arduino. Open the serial monitor and watch what happens when you change the pot.

  2. You may be misunderstanding the bargraph module. 5 volts lights all 5 leds, 4V lights the first 4, 3V the first 3, etc. I don't believe the individual LEDs are addressable.
