Learn about the Peltier Effect and how to use a common and inexpensive Peltier cooler to cool down your electronic projects. We will perform a few experiments with a Peltier module, including using it to make ice!
We will also hook up a Peltier Cooler assembly that you can get on eBay.
What do you do when you want to save data in your Arduino project and have it available even after the Arduino is powered down? One excellent way of doing this is by using EEPROM – Electrically Erasable Read-Only Memory.
In this article you will learn how to use both internal and external EEPROM with an Arduino.
One of the most important, yet most overlooked, aspect of building a project is designing a method of giving it power. Power sources like batteries and AC adapters are only half of the answer, you still need to provide logic-level voltages to safely power your devices.
In this article we will look at several methods of providing safe regulated power for your electronic designs.
