Let's wire up a way for RoboBrrd to tell if it is hot or cold! The TMP36 is a pretty sweet temperature sensor. With the text facing towards you, the leads from left to right are: Vin, Analog out, GND. See the below photos for more details on wiring it up!
1. Need the TMP36, and three long wires
2. Curl in the endings of the TMP36 leads
3. Also curl the wires, and attach them together
4. Solder the connections
5. Add heat shrink tube or electrical tape to the exposed wires, this is what it will look like when done!
6. Labels are handy too
Extra - Step 6
It's not gonna be a bird if it can't make sound! Here is a tiny speaker that we can make the RoboBrrd Brain turn on and off very quickly to make some sounds. We need the piezo speaker and two medium pieces of wire.
1. One piezo, two medium pieces of wire are the parts we need!
2. Hook and loop the ends of the wires together
3. Solder the connections, tug them gently to make sure they are not loose
4. Add some labels and tape. Does not matter which wire is Gnd or +
Extra - Step 7
Maybe you will want your RoboBrrd to have some googely eyes, because googely eyes are the coolest thing ever! The best way to mount them is by adding a drop of hot glue in the middle of the back of the eye. Then, gently push it against the circle bump of the LED. You should see it slightly deform the back of the plastic of the eye, this is okay. Make sure that the eye is on good and that you can't easily flick it off.
1. Need the front face and two googely eyes
2. Test out where the eye should go
3. Add glue to the middle of the back of the googely eye
4. Gently push it onto the LED
5. Let dry, and done!
Extra - Step 8
RoboBrrd Brain Board Mounting
The RoboBrrd Brain Board needs to be mounted to the bottom face of RoboBrrd so that it won't be moving around while inside the robot. In the packet of mechanical parts, there should be 4 flat head screws, 4 rounded head screws, and 4 stand offs. The flat head screws go through the bottom side of the bottom face. From there, the standoff can attach to it. The board gets placed on top of the standoffs, and then the round screws go through the top of the board and into the standoffs.
If you painted your RoboBrrd, you may have to make some adjustments around the holes with a knife to make sure the flathead screws can fit through. Be careful to not make the screws too tight!
1. For the first part, we need 4 of the flat head screws, 4 standoffs, and the base of RoboBrrd
2. Place the flathead screw through the bottom face, and attach the standoffs to them on the other side. This is what it will look like (you can't see the flathead screws in this pic)
3. Same view, but from above
4. Now we need the 4 rounded head screws, and place the RoboBrrd Brain Board aligned with the standoffs
5. Add in the screws and tighten gently, this is what it will look like- Done!

Connecting the WIRES!
Now for the crazy fun part of plugging in all of the wires! Make sure you move RoboBrrd's front face close to or attached to RoboBrrd's body. From there, you will be able to connect the wires via the screw terminals. The pin numbers that we use below are only suggestions, you can use any pin that you want. The wires labeled with Gnd are plugged in to one of the negative terminals, and the ones marked with a + or Vin are plugged in to the positive terminals. See the below photos for more details.
The servos are plugged in corresponding to how they were wired (see Extras Step 1). The above photo shows how they should be positioned. The view is from the left side of the RoboBrrd
1. First component to plug in is the TMP36. The Analog out is plugged in to A2.
2. The speaker is plugged in to D7
3. Adding on the front face to the rest of the RoboBrrd
4. Attach the LEDs to R: D3, G: D5, B: D6
5. A close up, kind of like a birds nest in here!
6. Add the LDRs to A0 and A1 respectively
7. Add the servo wires, and now it's done!
You are done wiring up RoboBrrd with all the extra components. Sweet! Now it is time to program RoboBrrd with all the extra components.Let's get started!
