//Compute average of a int array, given the starting pointer and the length int compute_average(int *avgs, int len) { int sum = 0; for (int i = 0; i < len; i++) sum += avgs[i]; return (int)(sum / len); } //Insert a value into an array, and shift it down removing...
INTERNET OF THING (IoT) Some manufacturers provide the ultrasonic sensor that has 3 pins. TRIG signal and ECHO signal are in the same pin. In this case, we need to use only one Arduino's pin for both purposes: generating a pulse to the sensor and measuring pulse from the sensor. ...
37款传感器与执行器的提法,在网络上广泛流传,其实Arduino能够兼容的传感器模块肯定是不止这37种的。鉴于本人手头积累了一些传感器和执行器模块,依照实践出真知(一定要动手做)的理念,以学习和交流为目的,这里准备逐一动手尝试系列实验,不管成功(程序走通)与否,都会记录下来—小小的进步或是搞不掂的问题,希望能够抛砖引...
// use this value to determine the size of the readings array. constintnumReadings=10; intreadings[numReadings];// the readings from the analog input intreadIndex=0;// the index of the current reading inttotal=0;// the running total intaverage=0;// the average intinputPin=A0; voidset...
// Now that we have five individual readings, average them to get one average load reading floatreadingsSum = 0; // Create a variable to store the sum of all readings // Loop through the array and add together all the readings
// advance to the next position in the array: readIndex = readIndex + 1; // if we're at the end of the array... if (readIndex >= numReadings) { // ...wrap around to the beginning: readIndex = 0; } // calculate the average: ...
Often, the elements of an array represent a series of values to be used in a calculation. For example, if the elements of an array represent exam grades, a professor may wish to total the elements of the array and use that sum to calculate the class average for the exam. The program ...

In this video lesson we show how to create a program that will input a list of grades, sort them into descending order, average them, and then find the high and low grades. This is a classic first year college programming assignment. We take you through it step by step. For you ...
