can someone help me... =(First step, make Arduino work with basic code for NewPing.
After you understand how the sketch works you can use variables to calculate speed.
Quoted from this link Speed Calculator
Assume, V - stands for average speed (velocity), T - stands for traveling time and D - stands for traveled distance.
Average Speed can be calculated by using the formula: V = D/T
Traveled distance can be calculated as: D = V*T
Traveling time can be calculated using: T = D/VUsing the formulas remember about the units. For example, if the distance is given in meters and the time is given in seconds, calculated average speed is given in meters per second.
sorry, im new with arduino..what do u mean by " First step, make Arduino work with basic code for NewPing."? from the ping sensor coding, i can get the distance, but how to get the value of times?
