i followed everything what they said check out the website here is
( i am not sure if they speak Spanish language since i am proud to be Deaf)
my Android were working connected to Bluetooth. i can see the red blink on Bluetooth serial module. it s working but
why did i get this on my Arduino by said "avrdude: stk500_getsync(): not in sync: resp=0x00"
any body knowledge about this to solution the problem?
even i try baud serial.begin(57600) and (115200) it still not get in sync.
void loop ()
char c = Serial.read();
if (c == '1') digitalWrite(13,HIGH);
if (c == '2') digitalWrite(12,HIGH);
if (c == '3') digitalWrite(11,HIGH);
if (c == 'A') digitalWrite(13,LOW);
if (c == 'B') digitalWrite(13,LOW);
if (c == 'C') digitalWrite(13,LOW);
