ADRUINO PROJECT

For this project you will need:

Part list for beginners:

 

 

Part list for ‘pro’ :

  • ATmega328p (with Arduino Bootloader)*
  • 28 pin DIP IC Socket
  • 16MHz Crystal Oscillator
  • 2x 22pF and 1x 100nF capacitors
  • 10K resistor
  • USB to Serial adapter**
  • 2x L293D ICs
  • Mini Servo Motor
  • 2x DVD/CD Drives
  • Prototyping PCB Circuit Board Stripboard
  • 4x 2pins Screw Terminal Connector (or 2x 4 pins Screw Terminal Connector)***

*You will need also an Arduino UNO board to program the ATmega328 micro possessor

**USB to Serial adapter will allow the circuit to communicate with the computer through the USB cable, just like Arduino uno does.

***Why to use screw terminal connectors? Because you don’t want to solder and desolder cables from stepper motors until you find the correct working combination.

Tools (only for ‘pro’ part list):

  • Screwdriver
  • Soldering iron
  • Solder
  • Cutting tool (e.g. Dremel) (Optional for cutting plastic parts)
  • Glue

Use the screwdriver to open them and take off them the rails. Next step is to choose our base for this CNC machine. I used one surface from remaining dvd ‘garbage’ stuff.Finally we will need to find something to attach the one of the stepper-rails vertically to our construction. (you will understand what I mean in our next step) Watch the above image.adruino video
