  • Neither can we. We can't read the number on the chip. Can you? – Majenko May 3 at 16:36
  • It may be an ULN2003, but thats pure speculation – chrisl May 3 at 16:45
  • @chrisl Looking at the pinout and wiring (what can be seen of it), you may be spot on there. Ground and + are in the right location, certainly. – Majenko May 3 at 22:05
