Decoupling capacitors are essential for reducing noise and ensuring stable voltage supply to your ICs. Let’s add decoupling capacitors to the ATMEGA328P-MU and MPU-6050.
ATMEGA328P-MU (U1)
You should use 0.1 µF ceramic capacitors close to the VCC and AVCC pins:
  • Between VCC (U1:4) and GND (U1:33)
  • Between VCC (U1:6) and GND (U1:33)
  • Between AVCC (U1:18) and GND (U1:21)
Connect them like this:
  • Place C1 (0.1 µF) between U1:4 (VCC) and U1:33 (GND).
  • Place C2 (0.1 µF) between U1:6 (VCC) and U1:33 (GND).
  • Place C3 (0.1 µF) between U1:18 (AVCC) and U1:21 (GND).
MPU-6050 (IC1)
Similarly, use a 0.1 µF ceramic capacitor for the VDD pin:
  • Place C4 (0.1 µF) between IC1:13 (VDD) and IC1:18 (GND).
Summary of Connections
  • Connect C1:1 to U1:4 and C1:2 to U1:33.
  • Connect C2:1 to U1:6 and C2:2 to U1:33.
  • Connect C3:1 to U1:18 and C3:2 to U1:21.
  • Connect C4:1 to IC1:13 and C4:2 to IC1:18.
Would you like to proceed with these additions, or do you have any specific preferences for the placement of decoupling capacitors?
