    Question Sainsmart self-leveling Robot code.

    Not 4 bits but 4 nibbles (hex digits) i.e. 16 bits. Assume data = 000000XX XXXXXXXX 000000YY YYYYYYYY x = data >> 16; yields x = 00000000 00000000 000000XX XXXXXXXX (shift right by 16 padding with zeros from the left) as for y = data & 0x0000ffff; 0x0000ffff is hex for 00000000 00000000...

    Question Sainsmart self-leveling Robot code.

    There is some serious WTF here. This is what his code is doing (result of each step in bold) Joystick_1_X = analogRead(A0); Joystick_1_X = 00000000 00000000 000000XX XXXXXXXX Joystick_1_Y = analogRead(A1); Joystick_1_Y = 00000000 00000000 000000YY YYYYYYYY Joystick_1_X = Joystick_1_X << 16...

    There are four sources of light in the painting: the moon is accurately depicted and reflects off the calm water. There is a fire near the shepherds at left, where the family is headed. At the centre of the composition, Joseph holds a torch that illuminates Mary and the infant, who are riding an...

    Been there, done that. IMHO the correct way is to do the system in Python (or at least large parts thereof). Shoot me a PM if you want to discuss in depth.

    This manual is worth its weight in gold for any aspiring graphics designer, hence the interest. This, for example, is genius: W.r.t. the worm / meatball controversy: the meatball faction is/was driven by sentiment and have totally missed the importance of having a recognizable brand. The...

    Problem Lua error messages

    When programming Orbiter add-ons in LUA, a rather irritating problem is that the built-in run() function when fed with a script containing errors will only signal errors by saying Execution error. without giving the location of the error. With long scripts, this leads to lengthy bug hunts...

    Yes, you should be, and your graph should look like the one I posted in #9. (Minus the leftmost steep part, because you have never entered that region). That said, the shape of the answer box strongly hints that the author of the instruction expects the drawing like the one you've done in #1...

    Arrrrgggghhhh... Observe that they tell you to reverse the diode, so in the first experiment you are measuring +V_F and in the second experiment you are measuring -V_F. So despite the fact that the diode is now operating in reverse, you are still measuring positive voltage. That said, they...

    Here is a partal solution. The trick is to use linear graph instead of XY graph, which allows you to have arbitrary, equally spaced values on the X axis, and set both series to the same plotting style (which I didn't do for clarity): There are two problems, but both are solvable: - the first...

    If that is what I think it is, then this graph is simply wrong. Aside from the scale change, the current in the reverse bias region is negative.
