This shield sits on top of the Arduino Uno and extends the ports present, the number of digital (14) and analogue (6) pins remains the same, but each of them is provided with two more pins, one for GND and one for VCC (5V), this shield also has pins dedicated to the use of certain sensors such as 6 pins dedicated to the SD card interface, 4 pins for the SR-HC04 ultrasonic sensor, 6 pins for the HC-05 and HC-06 Bluetooth modules, 6 pins for the APC220 wireless interface, 4 pins for the I☬-Bus interface, 4 pins for the serial communication interface, 6 pins for the serial LCD display and 14 pins for the parallel LCD display. With a view to handling the Arduino, the kit includes a shield specifically designed to connect the various components. Furthermore, each module with an electronic component onboard has three or more holes that fit perfectly with the LEGO bricks, so in addition to the easy electrical connection, there is the advantage of perfect mechanical integration with the LEGO environment and also the physical support. Where I is the current absorbed by the LED, Vs the direct voltage of polarisation of the LED and V the supply voltage from which we start but in the case of the LED module supplied in the kit, we can connect it directly to Arduino without worrying about protections. It comes with a handout, and a tutorial manual, which will help you experiment with sketches to test the various modules with the Arduino Uno and the Sensor Shield (we will explain what this is short).īut what are the features of the ARDULEGOKIT and how are its components made? Well, the first one is that each electronic component is not the classic single component to be soldered, but it is soldered on a printed circuit board, therefore supplied in the form of a breakout board, thus allowing those who use this kit not to have to deal with soldering and to realise with extreme practicality and simplicity the connections required by the circuit they are going to design.Īs an example, if we wanted to connect an LED to the Arduino, we would normally have to calculate its falling resistance (R) using the formula:
Designing, building and having fun: this is the aim of the ARDULEGOKIT, available from Open Electronics (in a practical toolbox, containing, divided into small boxes, a large number of modules designed to be placed on LEGO bricks and used to create robotics applications and exercises.
