Getting Started Code / PulseSensor & "Arduino"
Choose the stabilizer ring for finger placement or the ear clip for earlobe placement. Follow the preparation steps before putting the sensor against your skin.

Try the pads, sides, or knuckles of your fingers on either hand. Place the covered sensing face against skin, not the nail. Use light, steady contact and keep your hand still. Try one spot at a time and compare the signal.
The ear clip, sensor, and clear face cover are included in the kit. A hot-glue gun and glue are required and are not included. Use a low-temperature gun with compatible, plain, non-toxic glue sticks. Keep glue off the sensing face and let all glue cool fully before handling or wearing.
