Download (Git): Now all the files are hosted in GitHub: https://github.com/carlosgs/ArduSkybot/tree/master/Electronics == Circuit board that simplifies making Printbots based on Arduino UNO! :) It is one-sided so anyone can make it easily. Features: -Two light sensors (LDR) -One ultrasonic distance sensor -Two buttons -Four LEDs -Four servo-motor connectors -Compatible with CNY70 board (http://www.thingiverse.com/thing:26819) Component values: The cap is 1000uF 6.3V (between +5V and ground), LED resistors 330ohm, LDR resistors 33kohm Instructions You can use one of this methods to make the PCB: youtube.com/watch?v=QQupRXEqOz4 instructables.com/id/Toner-transfer-no-soak-high-quality-double-sided/ (this one didn't work for me, you should try it anyway...) I have uploaded also the connection diagram so you can see the components :) Modifications (will be added in v2.0) You should power the Arduino with at least 9V and place a capacitor in the 5V line when using servomotors (otherwise the board will reset due to voltage peaks). It is a good idea to add one diode in series with the power line for the servos, this will help minimize voltage peaks that affect the 5V line.
