How do i key in a 4x4 matrix keypad input into arduino and control the brushless motor?
I need to use a 4x4 matrix keypad to key in the value ( or angle 0-180) using a servo library to spin a brushless motor. i was thinking of typing each character and then put them in an array. After that, change it to interger using atoi. how do i do that?? taking the pressed numbers from the keypad, put it in array and then change it to integer to run the bldc motor.?? help pleeeasseee.... an explanation and coding sample would be a great help..
