At each degree, the Ping))) sensor returns back a distance reading. The Arduino program sweeps the servo back and forth over a 90deg arc. So the “Ponar” was born: Ping))) + Arduino + Servo + Processing = Ponar. I was looking at my bucket of parts and it dawned on me: I have a servo, I have a Ping))) sensor, a spare Arduino Uno, a bunch of Erector Set parts, and knowledge of Processing programming: I could (should!) make a simple sonar system. Since I’ve never worked with any of these components before (servo’s, ultrasonic sensors, motor-drivers, etc), I want to break down each step so I can really grasp how this stuff works. My thought is to hook an ultrasonic sensor to it, to do some simple obstacle avoidance. While at the last Maker Faire, I picked up a 4wd robot kit. Trinket Comments Off on First steps with the Adafruit Trinket Next up, I really need some batteries to make a standalone project with it… 2014 03 /01 CATEGORY Electronics The above image has two servo’s hooked up to the same pin, so they move the exact same way. However, I was unable to create two separate servo objects: I think I don’t quite grasp the Trinket pinouts. Thanks to the “ Trinket Servo Control” tutorial, and their “ Adafruit SoftServo” library, I was able to make it happen. Earlier in the day I had done some servo programming on an Arduino, and I wanted to emulate it on the Trinket.I was able to successfully run all their examples from the page “ Programming with Arduino IDE“.

And other than a few path differences it worked just fine. So instead I had to use the “Slow Way” example they gave.

Since I’m on a Mac, I didn’t have to worry about installing any drivers, but the “Mac Arduino IDE” app download they provided didn’t work.

Setup my pre-existing Arduino IDE for use with the Trinket, following these Adafruit docs.

Here’s the streamline approach I finally took: There’s all this talk of installing AVRDUDE, etc, but as it turns out it’s really not needed (if using the Arduino IDE).

Adafruit Learning System: Trinket (many, many Trinket examples)įor all the documentation on the web, I really wasn’t sure where to start.
