Question

What ti do in arduino if lvalue required as left operand of assignment

Answer 1

Answer:

The code is reading in buttons though an analogue port. This is where the error is (in void(loop)):

while (count < 5){

buttonPushed(analogPin) = tmp;

for (j = 0; j < 5; j++) {

while (tmp == 0) { tmp = buttonPushed(analogPin); } //something wrong with the first half of this line!
