all wired up i think?

just not sure on how to set up ports and pins.

i believe im connected to input 12. so i activated input 12.

but im getting no reading still

oh right but i dont actually need them if i have the other sensors?

i didnt get round to wireing tonight as i made one of these from scratch again -




could i just confirm before i wire tomorrow

so i apply 5v to white wire of sensor
add resistor then 5v to red wire of sensor
connect green and black wires to 0v or gnd of 5v psu
connect blue wire to input/break out board?

ok found a suitable resistor.

so is it the blue wire that goes to the input on my break out board?

all help welcome

just got two opb916b's today.

but i forgot about the resistor, is the resistor 100% needed?

also what is the BOB?

ah they call it something different, good old maplins.

im assuming its exactly the same and wired the same? (electronics is not my fing)

**
A slotted disc attached to the spindle, an Optek OPB 916B optical switch and a 220 Ohm resistor are all thats required. Take 5v from the BOB to the white wire on the opto, take the same 5v source to one end of the resistor and connect the other end to the red wire on the opto. Connect the Green and black wires of opto together and connect to 0v (Gnd) terminal on Bob. Take blue wire from opto and put to an input on the BOB. In Ports and Pins, Inputs set p the Index to the port and pin you have it connected to.

BTW Mach has to be licensed for threading just in case you are in demo and wonder why it doesnt work.
