I’ve been whining about wanting to learn GitHub for a while now so after they just released a shiny new Windows Graphical User Interface (GUI), I figured it was time to jump on board. Everyone I know who uses Git

Robotic Arm in Processing
I’ve been doing some pretty heavy reading and writing for the last few days, so I took some time “off” this afternoon to work on a mini project that I had been thinking of for awhile. I wanted to write
Continue readingSeeing Sensors: How to visualize and save Arduino-sensed data
Sometimes when you’re prototyping a project it’s nice to see what’s going on with your sensors or variables in your code. Sure you can watch analogRead() values scroll at warp speed on your Arduino Serial Monitor, but what if you
Continue readingCurrent Sensing with the ACS712 Hall Effect Sensor
After a conversation with JD Warren, one of authors of the excellent Arduino Robotics book, I decided to try the ACS712 hall effect current sensor. I soldered one to a surface mount to breadboard adapters and plugged it in with
Continue readingDigital signal processing and filtering – motor current sensing
After a recent post on current sensing, I talked to a couple of friends at NYC Resistor (my usual sounding board) and got some great advice (as usual). One thing I didn’t remember was the difference between passive and active
Continue readingCurrent Sensing and Visualizing with LabVIEW for Arduino Controlled Robotic Arm
In my last post, I talked about using an RC filter to get rid of some of the noise in the current signal I was getting from the Arduino. While this worked okay, I still wasn’t super happy with the
