I’m doing a group project for one of my university courses which will involve line following. We have £200 to spend and I really wanted to get hold of 4 of your QTR-8RC parts but unfortunately, we are only allowed to use parts from RS components and onecall.farnell for the finished machine.
I’ve looked at the circuit diagram you give in the documentation for the QTR-8RC:
but I can’t seem to find values for the IR LED’s, phototransistors or the MOSFET.
(I’m also not entirely sure if this diagram is for the 8RC or 8A)
I brought one of your sensors off your amazon store to have a look at it but I can’t see markings on the phototransistors or IR LED’s. At least not without taking them off the board.
Is there any chance you could give me the the part numbers or at least the values of the phototransistors/IR LED’s and the MOSFET? If we can design the circuit in Target then our technician will engrave us the PCB.
