Hi, so I'm completely new to arduino and have started with a project well above my knowledge. It's a robot-project having 7 microservos and 2 DC motors. I use an arduino r3, i2c servo controller board (Adafruit 16-Channel 12-bit PWM/Servo Driver) and a Velleman VMA03 motor shield. See picture for wiring.
I realized that my motor shield doesn't have a SDA/SCL pin, but I thought I could just connect the jumper wires directly into the uno before attaching the motor shield. However, when I do this I can't control the servos. Everything works fine without the motor-shield (but obviously I cant' control the DC motors). So, is my assumption of connecting the jumper wires directly into the uno wrong? Do I need to get a new motor-shield?
