Hi guys
Sorry for the weak title, but it is difficult for me to explain I have a wav/MP3-trigger that can play a sound when a pin is grounded. To access more sounds, one of the pins (that you ground to play a sound) has to be connected to one of the other pins (that can also be grounded to play a sound).
So, let's say I have two pins, 1 and 2. If I connect any of them to ground, their corresponding sound will play, sound 1 or sound 2. If pin 1 is connected to pin 2, sound 3 will play etc. (if pin 1 is connected to pin 3, sound 4 will play)
How do connect pin 1 to pin 2 with the output from a microcontroller? Should I use something like a transistor or TTL?
Thanks for reading!
