Kit Assembly

The assembled kit looks something like this: TODO To put this together, you'll need:

• Case
• Bag of screws (two metal, four plastic) that came with the case
• The "harness" kit (the black plastic plate and associated screws, rivets, etc.; these were in short supply on the day of the event, if you didn't get one on the day then you'll need to wait until new stock comes in)
• Akeru
• Grove Base Shield
• Grove microphone, PIR, ultrasonic and dust sensors

The major constraint in assembling the kit is the Akeru's antenna - which limits the placement options for the Akeru - combined with the limited number of mid-sized holes for the mounting rivets. In fact there is only a single mid-sized hole that can can be used with the Akeru. (This differs from the simpler Arduino Uno mounting that the harness kit was designed for, in which there is no antenna to get in the way so all four holes can be used. Fortunately it turns out that one is enough.)

The usable hole in the harness is this one: TODO

The usable hole in the Akeru is this one: TODO

The rivet and collar from the harness kit to connect them looks like this: TODO

To assemble the kit:

1. Use one rivet to attach the Akeru to the harness. TODO describe better.
2. Press the Grove Base Shield into the headers on the Akeru.
3. Attach the microphone, PIR and ultrasonic sensors to the harness in any arrangement you like; the photo above provides one example.
4. Connect the PIR and ultrasonic sensors to any digital inputs except D8 (save that for the dust sensor). In the photo above they are connected to D2 and D3 respectively.
5. Connect the microphone to any analog input. In the photo above, it's connected to A0.
6. Connect the dust sensor to D8. The dust sensor provides a PWM signal which requires pulseIn() to demodulate. On an Arduino Uno (and therefore the Akeru), pulseIn() is believed to work with D8 only. Don't attach the self-adhesive stand-off yet, there is a decision to be made about orientation first if you intend to contribute data to the Yahi haze-mapping project.
7. Place the harness in the bottom of the case, wiggle the Akeru and its antenna until everything fits.
8. Insert the two metal screws to attach the harness to the case.
