Pinout Connections​

I2C Display (OLED/LCD):​

  • PC0 → SCL (with pull-up resistor)
  • PC1 → SDA (with pull-up resistor)

UART Serial Communication:​

  • PD0 → TX
  • PD1 → RX

DS1302 RTC Module:​

  • PD2 → CLK
  • PD3 → DAT
  • PD4 → RST

Speaker/Buzzer:​

  • PD7 → +SPK (positive terminal)
  • GND → -SPK (negative terminal)

Ensure your power lines are clean and filtered when dealing with sound or communication modules to avoid noise or instability.
