Arduino Stepper: Ultimate Accuracy!

I’ve always loved automation equipment! A grade school trip to a museum with a marble machine using pneumatics, sensors, servos and more had me hooked.   Combining Arduino’s with mechanical devices and machined parts is just amazing. I’m working on a project using a stepper as a “feed device” and wanted to make a video experimenting with various ways to control the Arduino Stepper as well as measuring to see just how accurate it could be!  

Wireless RF Remote & Receiver! Easy & Cheap! Great for Arduino and Raspberry Pi!

A review of Adafruit’s inexpensive RF keyfob remote and receiver. This is by far the easiest and least expensive RF solutions I’ve seen! It’s a “turnkey” solution – e.g. it works right out of the box. It can directly control things (like an LED or transistor) or be used to trigger a digital input pin on an Arduino or Raspberry Pi!  

Arduino Wireless Mobile Data Logger with Sonar and Xbee

Measures and logs temperature and light levels.   Two mode of operation: Automated – moves on its own avoids obstacles using distance sensor. Also plots the distance/sonar data into processing Manual – Manual Control using keyboard or buttons on the application.   Wireless control and data acquisition: Communications using to Xbee modules. Base Xbee used to transmit data form custom processing application. Base Xbee used to received sensor data sent from the mobile data logger.   Processing Application: Display data received from mobile data logger Display sonar data when in automated mode Send control data to mobile data logger using…
