> There are three types of motors that makers typically consider: stepper motors, servo motors, and DC motors (either brushed or brushless). Stepper motors are great when you need high precision and torque, but tend to have jerky movement.
> While we adults don't experience them often, school kids practice fire drills on a regular basis. Those drills are important for safety, but kids don't take them seriously. At most, they see the drills as a way to get a break from their lessons for a short time.
> Love your plants, but also have a life? If you work long hours, travel often or just can’t be tied down to a regular schedule, the Arduino Plant Watering Kit is for you.
> DSM (digital spectrum modulation) is a relatively new radio control technology that is ideal for long-range applications. It uses two methods, FHSS (frequency hopping spread spectrum) and DSSS (direct sequence spread spectrum), to transmit data, with the latter being especially resilient to interference and therefore suitable for transmission over long distances.
> Biometric identification and authentication is big business. As an example, consider Apple's Face ID technology, which has made strong smartphone security both user friendly and readily available. But Face ID requires substantial hardware and computational power to work, which makes it ill-suited for applications where cost is a major concern.
