You can refer to the Fritzing diagram on the Overview Page for the parts placement.

Vous pouvez vous inspirer du [[Trinket-Alarme|diagramme Fritzing présenté dans l'introduction]] pour placer les différents éléments.

I used two pieces of female header, 5 pins each, to mount the Trinket to the board. Single male pins are placed on the - line, the Trinket BAT+, and Trinket Pin 0 for connecting Bluefruit later although you can use hook-up wire if you like.

Vous pouvez utiliser 2 sections de connecteur femelle à 5 broches chacune pour monter/démonter plus facilement le Trinket sur la carte. Vous pouvez également utiliser des {{pl|97|PinHeader Extra Long}} pour souder définitivement (et surélever) le Trinket.

Four resistors provide the analog divider to multiplex three sensors. The 1500 ohm resistor (the large one in the pictures, your size is probably smaller, I used what was on hand) goes between the trinket 3.3 volt regulated pin to the common resistor junction. Each of the other resistors is connected to this common area and connected to Trinket Pin 3 (Analog pin 3). Four wires are run off-board to connect the sensors.
