After the success of BuildCircuit’s first Amarino Shield for Android-Arduino experiments, we are here with Amarino Evaluation Shield. I am grateful to all the customers and readers who purchased our first kit and gave us their wonderful comments. About Amarino Evaluation Shield: Amarino Evaluation Shield is for Amarino toolkit and most of the available Android…
A breadboard is a device for testing temporary electronics projects. Components used to test a circuit can be reused for other projects. None of the components are damaged.
Almost all people start to learn electronics using breadboard because it is the simplest way of making circuit. The photograph shows a typical small breadboard which is suitable for beginners building simple circuits with one or two ICs (chips).
This is a basic electronic clock built with  STC15w408AS, clock chip DS1302, and 16×2 LCD. The best thing about this kit is its enclosure. With all the features of a commercial clock, the kit gives a professional look after assembly. The article shows you all the steps to build the electronic part of the kit…
This project has been derived from this basic experiment. I recommend you to do the basic experiment before you go for this experiment. In this experiment, we use an Android smart phone to control the 3mm LEDs of the Amarino shield.
