text: Hi Im new to programming ini general, Ive been through the sample codes in "getting started with Arduino" and now Im trying out some sensors I have here. The first on eis the HC-SR04 ultrasonic I have it working using this code,
  /* HC-SR04 Ping distance sensor] VCC to arduino 5v GND to arduino GND Echo to Arduino pin 13 Trig to Arduino pin 12 More info at: */
  #define trigPin 12#define echoPin 13
  Hi I have a few NDs/Dsi batteries lying about is it possible to use them to power servos/arduino if they are connected together as they are only 3.7v 1000mha but are very light.
  Hi I got a Dagu quadbot and a Dagu spider controller and am trying to adapt the quaruped2 code to make it move but I havent had much success,What does FLHservo,FLKservo mean ? I get the front left bit and I think I have assigned them the correct pin in the code as follows,
  #include <Servo.h>#include "Constants.h"#include "IOpins.h"
  // define global variables and servos here
  int Time=100;int LShift=350;int RShift=350;int Raise=700;
