ELM415 - Up/Down Interface
The ELM415 is an 8 pin device that simplifies the connections between a pushbutton type human interface and many counter-based circuits.
Counter circuits are often employed for such things as temperature control, audio volume control, level settings etc., but some require a direction and a step inpu
