    @Holly,

    Good morning and Happy New Year!

    I’m in the “Proto typing” section; “Prototyping with the PIR sensor”;  3rd SLIDE down, under “TASK: Prototyping the PIR Sensor”, Materials… it says “1x LED” and shows a WHITE/CLEAR LED.  No mention of a breadboard.. even though one is showing later on under “Making Connections”…. and there’s MANY MORE jumper wires being shown and of different types.

    “Draw the Circuit Diagram”… the diagram shows a 5v power source.  The verbiage states that GPIO pins have an output of 3.3v.  The 5v power source would overpower the 3.3v GPIO pins, right?  GPIO pin #2 and #8 are in the Digital PWM section of the Arduino board.  Power is on the other side of the board.

    In that same paragraph, it uses a RED LED as an example for the circuit.  Red =1.8v forward voltage.  White = 4.0v forward voltage.

    “Making Connections” shows a WHITE LED verses a RED, for which the calculations were done for.

     

    Am I being too critical?

    Hi Leo,

    No, you are not being too critical. These are the types of issues we are trying to eliminate with this version of the product. The goal is to be as consistent, accurate and concise as possible.

    Thank you for this feed back. It is on our to-do list to edit.
