A few days ago I tested a circuit on a breadboard based on a ATmega8a with 1 MHz internal oscilator. It sould turn on and off a relay based on a IR code that is received and if it matches the programmed in the EEPROM it shoud enable or disable the relay. Now I developed a PCB and soldered everything together but now it isn't working. On an Arduino Nano it is working ok.
#include <IRremote.h>
#include <EEPROM.h>
int RECV_PIN = 11;
int RELAY_PIN = 4;
int setpin = 3;
unsigned long work_at;
unsigned long adres;
unsigned long irbuffer;
IRrecv irrecv(RECV_PIN);
decode_results results;
void dump(decode_results *results) {
if(digitalRead(setpin) == 0){
work_at = results->value;
Serial.println(work_at, HEX);
}
irbuffer = results->value;
}
void eeprom_writer(){
if (irrecv.decode(&results)) {
if(digitalRead(setpin) == 0 && work_at != 0){
EEPROM.put(0, work_at); //put walue
Serial.println(work_at, HEX);
adres = work_at;
Serial.println(adres, HEX);
delay(1000); //wait
}
}
}
void setup()
{
EEPROM.get(0, adres);
pinMode(setpin, INPUT_PULLUP);
pinMode(RELAY_PIN, OUTPUT);
Serial.begin(9600);
irrecv.enableIRIn(); // Start the receiver
}
int on = 0;
unsigned long last = millis();
void loop() {
if (irrecv.decode(&results)) {
// If it's been at least 1/4 second since the last
// IR received, toggle the relay
// if(&results == adres){
dump(&results);
if (millis() - last > 250) {
on = !on;
if(on == true && adres == irbuffer){
delay(5000);
digitalWrite(RELAY_PIN, on ? HIGH : LOW);
dump(&results);
}else if(on != true && adres == irbuffer){
digitalWrite(RELAY_PIN, on ? HIGH : LOW);
dump(&results);
delay(5000);
}
}
//}
// Serial.println(dump(&results));
// Serial.println(count, DEC);
eeprom_writer();
last = millis();
irrecv.resume(); // Receive the next value
}
}
