Well, your rate is so low that you can measure the period in software.
You can either use the capture compare, or just catch the times in
software. Say you have a 100uS timer tick. At 1/6Hz, or 6Sec, you will
have a 1 in 60000 resolution. Capture the edge to edge on the RB0 pin,
or just poll, and run a counter in Timer0. You will have a fresh value
every pulse, or every 6 Sec. If you are concerned about bogus readings
or bobble on the display, then low pass filter the readings with an IIR
style filter.
