So Im reading the code someone put up for their "family" of mini robots and one part isn't making sense. Here is the part of the code:
for(i=0; i<4; i++){
lsenseval += analogRead(lsensepin);
rsenseval += analogRead(rsensepin);
}
lsenseval and rsenseval are just two variables defined as types uint16_t. And lsensepin and rsesnsepin are just two phototransistor pins.
So I searched google and this site, but couldn't really find anything on what =+ means. Can someone help me out? Thanks!
