 | | Picking a PIC
|

I'm looking to offload the processing of IR proximity sensors and ultrasound to a PIC(s). I'm hoping to connect the PIC to a HandyBoard via the SPI. I'm trying to decide which is the right PIC for the job. The PIC16C7x (PIC16C76) series supports (...) (26 years ago, 27-Oct-98, to lugnet.robotics.handyboard)

If you go look at the imagesco page the sensor is the Part number FLX-01 and they are priced at $10.00 each. This is where I got my $10 quote ;^( I guess there was a 50% raise in the price since Fred Martin updated the FAQ... Thanks anyway. -- Eric (...)
