Making the robot safe

In the previous part of the chapter, with our multiple attempts, we have been able to find the maximum positions for each of the servos. Now it's time to use these values. In this chapter, we will be programming the servos for what its absolute maximums are. In this program, we will make sure that servos will never need to travel even a degree beyond the defined parameters on both the sides. If the user gives a value beyond it, then it will simply choose to ignore the user inputs instead of causing self damage.

So, let's see how to get it done. There are some parts of this program, where the numeric values have been bold. These are the values that you need to replace with the values which we have noted in the previous section of this chapter. For example, for servo 1, the values noted down are 23 and 170 as the maximum values for either side. Hence, the change in the code will be from if a[0] < 160 and a[0] > 30 to ifa[0] < 170 and a[0] > 23. Similarly, for...
