Using four I2C connections, you can attach more than 4 meters of sensors to your creations. It includes an ATTinny85 microchip which is programed using an Arduino board in Arduino ISP mode.</p><h2 style="text-align: left">What is I2C?:</h2><p style="text-align: left">"I2C stands for the inter-integrated controller. This is <strong>a serial communication protocol that can connect low-speed devices</strong>. It is a master-slave communication in which we can connect and control multiple slaves from a single master. In this, each slave device has a specific address." "Tutorialspoint.com"</p><h2 style="text-align: left">What is Arduino ISP?:</h2><p style="text-align: left">The Arduino ISP is<strong>an In-System-Programmer that is used to program AVR microcontrollers</strong>. You can use the Arduino ISP to upload sketches directly on the AVR-based Arduino boards without the need of the bootloader.</p><p style="text-align: left"><a href="https://www.instructables.com/How-to-Program-an-Attiny85-From-an-Arduino-Uno/" rel="nofollow" target="_blank">Here is a tutorial on Instructables on how to program an attiny using an Arduino UNO: </a></p><h1 style="text-align: left">Building and Assembling:</h1><h2 style="text-align: left">Soldering:</h2><p style="text-align: left">Soldering the board is a very straight-forward process; first, solder the attiny chip facing the top of the board (as shown in the 4th photo), then solder a male pin on each of the pins. And lastly, solder the push button in its place on the board.</p><h2 style="text-align: left">Printing:</h2><p style="text-align: left">For the 3d-printed parts, I used PLA and printed the parts at 15% infill. The bottom part doesn't require any supports but the top part does.</p><h2 style="text-align: left">If you followed the steps closely, you should have a finished brick by now.</h2>
