SIMA Mainboard
MIŠIĆ Feb 11,2025
SIMA (The small independent mobile actuator) is one of our projects for Eurobot 2025 competition. A microcontroller that we use on this SIMA is Arduino Nano, which is easy for programming and realisation of all small projects. We have two Ultrasonic sensors for control the movement of the robot, one small buck for convert the voltage to 5 V DC. We also use two FS511R motors for the movement.

KeyPROM Prototype
Coder Feb 11,2025
This early prototype makes use of an on board cryptographic co-processor to provide security functions and encryption for the data transfer,The co-processor will also be used to store the secure key for the encryption as well as a counter for HOTP to be sent with the authentication packet. There will be another project which will be the reader for this "key"

Hourglass ESP8266 Code
Pavleski Feb 06,2025
 A hourglass, also known as an sand clock, is a device used to measure the passage of time. It consists of two glass bulbs connected by a narrow neck, through which sand flows from the upper bulb to the lower one.  The flow of sand is controlled so that it takes a set amount of time to completely empty the upper bulb. Hourglasses are often used as time management tools and decorative items. This time I will present you a very simple way to make a digital version of such a clock. T...

Line Follower Robot using Arduino
Jain Feb 05,2025
A Line Follower Robot (LFR) is an autonomous robot that follows a predefined path, typically a black line on a white surface or vice versa. This guide will walk you through building and programming an Arduino-powered Line Follower Robot from scratch.How a Line Follower Robot WorksThe robot detects and follows a line using IR sensors. Black surfaces absorb most light, while white surfaces reflect it. The IR sensors, consisting of an IR emitter (LED) and an IR receiver (photodiode), use this princ...

Tug of War Arduino Game on WS2812 Led strip
Pavleski Jan 30,2025
 A Tug of War is a classic team-based game where two opposing teams compete to pull a rope in opposite directions. The objective is to pull the other team across a certain marker (often a line or flag) positioned in the center of the rope. This time I will describe how to make an Arduino version of this game for two players. In fact, each player represents a team and has its own color. Thanks to the LED strip with programmable RGB LEDs with a built-in WS 2812 chip we can make this game...
