@follower: We're making some headway- Thanks for your input so far. Taking your reply a paragraph at a time:
- I have that PDF. It's the one I've been trying to figure out.
- Correct, except I need to use multiple buttons & multiple motors.
- In section 4 of the PDF I see
vw_set_tx_pin
extern void vw_set_tx_pin(uint8_t pin);
which I understand is for setting the input pin, but I can't seem to find an example of it anywhere else that gives me a clue how to use it. Where does the pin number go?
I also need to know if I can use that instruction, say 10 times in the one sketch to set 10 input pins.
I keep referring to the Arduino Primer (may not be its correct name) I downloaded months ago, which got me through simpler sketches, but Mike's PDF almost looks like a different language!
