oric_dan,
How do you have the sensors wired? Are they in the daisy chain? Is that why you have TX and RX?
void read_sonar(int txpin, int rxpin, int* ary, int asiz)
{
pinMode(rxpin, INPUT);
Why is rx an input?
if(countL>prevCountL&countL>maxCountL){
s/b:
if( countL > prevCountL && countL > maxCountL ) {
or as I prefer:
if( (countL > prevCountL) && (countL > maxCountL) ) {
Did you change this in your code that you're using now?
Could you post the code that you're using now? Thanks
