Is there a way to have an Uno run in a loop by jumping 2 connections, not by code, much the same way you can with a Picoboo? I'm wanting to run it with relays connected without a PIR and have the sequence run over and over? So basically when power is applied to the UNO it's starts playing the...

Hey all. Trying my hand at DIY props this year. Looking to go Ardurino over Pico as it seems to be less expensive. So, sorry if my question is too vague or open ended. Basically I'm doing an human interactive electric chair with electric sander, vibrating motors, flash cracker and routed fog...

Here is my take on the monster in a box. The box use to be a bedroom 3 draw chest. Completely self contained. Controlled by a Four banger setup, powered by a 12v battery and a 9v for the Uno R3. Actuator is surprisingly powerful for it's size and price (£1.85)...

Got my monster in a box operational today! I still have to tweak the timing a bit and add a few little cosmetic details but I thought i'd share it. It's all ran by an Arduino uno, two cylinders and two solenoids. I've got a small PIR sensor to trigger it all and then it runs for 30...
