Parallel circuits are one of two fundamental circuit configurations we come across every day. Like a parallel universe, parallel circuits and networks can give us unexpected results. Adding more gives less, and voltage stays the same no matter what! Learn about the role resistance plays in parallel circuits for your designs and safety.

The LM35 is an ideal temperature sensor for measuring ambient temperature. It provides a linear output proportional to the temperature, with 0 V corresponding to 0 degrees C and an output voltage change of 10 mV for each degree C change. LM35s are easier to use than thermistors and thermocouples because they are so linear and require no signal conditioning.

Qi (pronounced as "chee") charging is an optimized inductive charging concept also known as “wireless charging,” allowing you to charge your devices wirelessly. Compatible devices’ batteries are charged by using induction transfer without requiring separate chargers, cables or adapters... Simply place your compatible device on top of the wireless pad and watch your device charge. Finally--an end to cords!

In some Arduino applications, it is advantageous to be able to store and retrieve information locally. You can do this with a Secure Digital, or SD, card. An SD card is a non-volatile memory card used extensively in portable devices, such as mobile phones, digital cameras, GPS navigation devices, handheld consoles, and tablet computers. Another type of SD Card is the Micro SD card. Measuring only 15 mm x 11 mm x 1 mm, it is the smallest memory card available. It is about one-quarter the size of a normal-sized SD card, or about the size of a fingernail.
