I tried to make Real Time Clock using DS1037. But the output in serial monitor is garbage. I attached my circuit and the serial monitor output in this question. The crystal I used is of 32.768KHz and pull-up resistor of 2.2KOhm. Can anyone help me to solve this problem? Thanks in advance…
I don't see a common ground from the arduino to the RTC.
I believe all those 165s indicate inadequate power.

I didn't do the common ground. I connected ds1037's 4th pin to the negative of the button cell.

I also tried giving arduino 9V external power supply.

Well without the ground, the 5V to pin 8 has no meaning; it’s like the sound of one hand clapping. So that’s really the source of your inadequate power: there isn’t any.
