Strange Resistance Reading in Autonomous Tracked Robot Circuit
Hello guys,
Recently, I have been building a tracked robot that moves autonomously (avoiding obstacles, etc.). I bought new components that I soldered onto my prototyping board. Before coding, I wanted to test everything first (connections, short circuits, bad solder joints, etc.). So, I checked with my ohmmeter if there was a short circuit between the positive and negative, and the multimeter showed 187 ohms! Strangely, I don't have any resistors of that value in my circuit.
If you can help me understand where the problem comes from, I would be very grateful. Attached is a diagram of my circuit and the location where I placed the ohmmeter (made on virtual graph paper).

PS: The TXB0104 is a logic level converter, the BMM150 is a compass, the HC-SR05 are ultrasonic distance sensors, and the Adafruit Seesaw is an i2c expansion.
