This seemed like a fun first project. Baby Einstein xylophone uses metal detectors under the wood cover and LEDs. The last image I flipped vertically so it matches the second and you can see what’s going on underneath. Top left affect the lights, top right the sensors. There aren’t many other resistors… it looks like R13 goes to the speaker (lower right set of wires out) from the underside. Though there is no resistor there. Touching resistors to it doesn’t seem to do anything. Is it connected to those solder points, already joined? Im really new to this but have soldered kits before, but not sure how I should be testing points for bending? I thought I could touch a resistor to the resistors but itll just take the path of least resistance right? Trying to just bridge the ends of components hasn’t done anything. How does one probe for points? Or is this just too new and all in the black blob? Thanks
