BAS120 pinout

This post is a follow on to this one.

It is a little unclear which pin on the BAS120 printer module is which. In the images below, RX/TX is white, 5V is red and 0V (gnd) is black.

The easiest way to connect an Arduino board to the module is to solder jumper wires to the three holes (which connect to RX, 0V (gnd) and 5V) as shown below.

These three holes appear incorrectly labeled from the front of the module (red side) because the text refers to the header that is normally used to connect to a basic stamp. The back side (green side) of the module correctly labels these pins (shown in red in the second picture below).

The TX pin is marked on the Arduino as TX. It is pin 1 (the second pin from the bottom) of the digital pins.

My name is Carl Testa. I am a composer based in New York City and New Haven, CT in the US. I have been following your blog for a while now and I have really enjoyed your posts on technical matters and I really enjoy your music. Something about your aesthetic is really appealing to me. I find your music to have a sharper edge (or duller and noisier edge?) than other chip-based music. "When Dinosaurs Roamed The Earth" and your new "Five-Step Plan" are my favorite albums.

Anyway, I wanted to share with you some of my music. I just released my first disc as a leader entitled "Uncertainty." It features compositions for clarinet, percussion, and electronics. I am also working on an electronic album called "Kalle." I program most of the electronics in SuperCollider. One piece called "Kalle" uses granular manipulation of sound samples of printers, scanners, and heaters. Another piece recorded live uses some emulated Atari 2600 sounds and live sampling of a printer. I have been trying to program the printer so that I can control it, but I haven't gotten the technical side of it working yet. So in the performance I am just printing out text. But it is effective for the purposes of that piece.

If you send me an email address I can send you the links to download the music. I would love to hear your thoughts on this work, and I look forward to hearing more of your music and learning from your blog.

Thanks So Much,
Carl (email: carl (at) carltesta (dot) net)
