Today we’ll expand Arduino’s digital resources thanks to an I2C bus equipped shield and we’ll allow the management of the board via a bluetooth connection RN-42 through an Android systems. All Arduino boards feature a number of digital I/Os. For the simplest projects, such resources are usually more than sufficient, but in those where they…
With 10 million Arduino UNO sold worldwide, this board becomes the most widespread prototyping board ever. The first Arduino UNO board was introduced in 2005 and in those days integrating a communication system such as WiFi was extremely expensive. So why not think of something that would allow all owners of this board to make an…
Small module for Raspberry Pi equipped with 5 megapixel camera (Omnivision 5647). It is capable of taking pictures with a resolution of 2592×1944 pixels. The small module, which has dimensions of only 25x24x9 mm and weighs 3 grams, can also shoot HD video in 1080p format at 30 fps, giving the possibility to users of…
The entire remote control is handled by a PIC that controls the GSM/GPRS module’s activity and gives commands to the two relays. Having said that, let’s take a better look at the electric scheme: power is supplied by continuous voltage, not always stabilized (applied to PWR + and -) at a value between 5 and…
