So today I opened up my Senseo because I wanted to attach an arduino with a Bluetooth module to the 3 buttons (for some coffee when my alarm goes off). I wanted to measure the voltage but after the most idiotic move I made I shorted out the circuit. Now except from the black stuff in the left bottom corner I can't really determine any damaged components (nothing blown, nothing molten, diodes still work).
Now my question is, is it wise to keep on using this PCB or how do I test if the PCB still works?
Thanks in advance!
I cleaned the PCB and it looks good to me. The leftover burnt places are contactpoints of 2 resistors which are still working.
