I'm brand new to this forum and also Arduinos in general. I'm currently in the process of making a Pinewood Derby track and just about have that side completed (needs varnishing and a bit more sanding, ...).
My next project is trying to make a timer. I've been following instructions from the USA but don't seem to be able to find identical components here in the UK. The first thing I'll need to do is set up the electrical hardware:
Inputs: 4 pairs of IR LEDs and receivers that I hope to use as the main inputs. 1x start switch (push to make) 1x reset switch (push to make) (I suspect long term I'll double up both of these switches and have ones up near the start gate as well as at the finish line.)
Outputs: 4x 8x8 LED matrix boards (these have the pins to allow daisy chaining) 4x 4bit 7-digit displays (not sure if these can be daisy chained - they have room on the circuit board but no pins - was thinking of just soldering the connecting cables into a chain) 1x solenoid / servo to operate the start gate (I've ordered both from Hong Kong but not sure which would be best to use)
If anyone could give me any tips with where to start in terms of information and how to set this all up I'd be really grateful. Let me know if you need any photos of the components I'm going to use.
The board is an Arduino Uno R3.
Thank you. :)
