BitZero Upgraded with Servo Shield and GPS

BitZero Upgraded with Servo Shield and GPS

In my last BitZero update, I installed a GPS module and began having a problem where the servos seemed to be glitching every second or so.  This turned out to be a resource contention.   The GPS module communicates to Arduino with interrupts, and this was disrupting the PWM pins from sending proper signal to the servos.  The solution turned out to be using the Adafruit Servo Shield.  The PWM processing is offloaded to the shield and can continue to run…

Announcing: Project BitZero

Announcing: Project BitZero

What is Project BitZero? I’m glad you asked. It’s the beginning of this journey to document all of my side projects.  And the first project is a prototype for small scale autonomous vehicles.  Being the first project, and being a software development blog, counting begins with zero. Each Bit will be a part of this blog, which is of course,  also a play on words for site’s theme: computer programming.  I will also cover many topics on wireless tech.  That’s…
