Arduino Uno, L293D shield, (2x) 12v Solenoid Valve, 12v 1a AC>DC Transformer (its an energizer battery charger transformer.)
The signal from the Arudino sends to the L293D shield np, as it has an led indicator to denote.
Both Solenoids work, but, they are salvage parts.
Solenoid in the A slot fires off perfectly fine, but the Solenoid in the B slot does not, despite being triggered.
(inconveniently mislabeled in the image i have. moter 1 slot not firing off solenoid, but, motor 2 is working fine.)
