I'm having a bit of trouble interacting with the Bleep Drum.

Using Arduino General Electronics

Hello,

I apologize if this is in the wrong section, but I think that this is the best place for it. I want to use a Sainsmart LCD shield to write a sequencer for my Bleep Drum machine that I built. This page (Bleep Drum User Guide & Hacking Info | Bleep Labs) shows the functions of the pads that I'm planning on using to interact with the machine. The "Tempo Out" pad (2) sends a high pulse every 1/8th, and the trigger pads all trigger when they receive a low pulse. How do I create/interact with these pulses? I apologize if this is too vague, but I don't know quite how I might wire or write code for this. I had tried a simple

digitalWrite(triggerPin, HIGH);
digitalWrite(triggerPin, LOW);
digitalWrite(triggerPin HIGH);

within the code (I tried performing this every 300 loops or so), but it doesn't seem to trigger anything. If things are triggered, they are triggered sporadically. To wire this, I tried going straight from the "triggerPin" to the pad. The pad has no soldered wire yet, so I was simply holding the wire inside/against the pad to try and test. I feel like I'm missing very important wiring steps or going about coding entirely improperly.

Again, I apologize if this is in the wrong place, but I'd appreciate any help I can get.

" every 300 loops" is probably far too fast. Put in "delay(1000)"

Or it might not be...we can't see your code from here.

PS: This should probably be in the "programming" area.

Alright, I'll move it over there. Thanks anyways though!
