Debug a Sketch

Sketch requires read 10 samples from Channel 1 and Channel 2 from ADC. Average the sample. Calculate a value based on the sample. Serial print the values. Here is what I have..not working. #include <MCP3008.h> // define pin connections #define CS_PIN 12 #define CLOCK_PIN 9 #define MOSI_PIN 11 #define MISO_PIN 10 // put pins inside MCP3008 constructor MCP3008 adc(CLOCK_PIN, MOSI_PIN, MISO_PIN, CS_PIN); // ADC reference voltage / calibration value #define V_REF 3.272 #define NUM_SAMPLES 10 int sum[2] = {0}; // sums of samples taken unsigned char sample_count = 0; // current sample number float voltage[2] = {0.0}; // calculated voltages char l_cnt = 0; // used in 'for' loops void setup() { // open serial port [login to view URL](9600); } void loop() { // take a number of analog samples and add them up while (sample_count < NUM_SAMPLES) { // sample each channel A1 to A2 for (l_cnt = 0; l_cnt < 2; l_cnt++) { sum[l_cnt] += [login to view URL](A1 + l_cnt); } sample_count++; delay(10); } // calculate the voltage for each channel for (l_cnt = 0; l_cnt < 2; l_cnt++) { voltage[l_cnt] = ((float)sum[l_cnt] / (float)NUM_SAMPLES * V_REF) / 1024.0; } [login to view URL](voltage[0] / (33 / 133)); [login to view URL]("\t"); // voltage 2 - B (pin A2) [login to view URL](voltage[1] / (33 / 133)); [login to view URL]("\t"); // reset count and sums sample_count = 0; for (l_cnt = 0; l_cnt < 2; l_cnt++) { sum[l_cnt] = 0; } [login to view URL](""); }'
