Remote telemetry on a budget!
As an additon to my arduino assisted RC truck project, I made a telemetry system for my truck, and I'm sure it will eventually end up being used on as a debugging tool on my robots too!
I used the following components from eBay (price includes shipping, but is approximate)
$10 RF links
$4 LCD screen
2 arduinos (already had them, and one of these will already be on any robot of mine)
free rotary encoder + ps2 decoder salvaged from a mouse.
I also ordered 10 thermistors ($2.50) but I haven't installed them yet.
If anyone has any ideas on how to calculate wheel slip, that would be fantastic!
