Using C programming

You have a plan to build a games console controller that captures the hand gestures of the player. The players movements and gestures are sensed using an accelerometer connected to one of the ADC pins of an Arduino. You have already written all the necessary code but have yet to include any kind of smoothing for the accelerometer signal.

Your task now is to write the accelerometer smoothing function. The function must take each new sample as input and return the average of 4 consecutive samples without introducing a significant lag. (Hint: use a moving average.)

Write an implementation of this function where the function prototype is of the form:

int SmoothSensor(int sensorReading);
