An IoT monitor for your laundry room

Arduino IoT monitor for laundry rooms

An IoT-enabled monitoring device for laundry rooms to provide an alarm and phone feedback when a water leakage is detected. It also monitors dryer vent for over temperature conditions and also notifies about the washer and dryer cycle completion. It uses Arduino, Ethernet shield, Blynk app and bunch of sensors.   This started as a quick project to provide an alarm and phone notification when a water leak was detected in our second floor laundry room. A couple of years ago the drain hose from the washer somehow came out of the drain and the water made a bit of a

Playing Tic Tac Toe against Arduino

Arduino Tic Tac Toe

Nick Koumaris of educ8s.tv has come up with another cool video tutorial showing how to build an Arduino powered Tic Tac Toe game. The gaming interface consists of a colorful LCD touchscreen that allows the user to play this fun game against Arduino. Let’s take a quick look at the code of the project. We need three libraries in order the code to compile. You can find links for the all the libraries in the description below. As you can see, even a simple game like this, require more than 600 lines of code. The code is complex, so I won’t

Arduino powered mini conveyor belt for training purpose

Arduino powered mini conveyor belt

Belt conveyors are key components of industrial automation systems. This modular mini conveyor belt is designed to replicate a miniature version of an industrial automation process that can be used in educational environments for industrial automation illustration using microcontrollers. It consists of a speed controller to drive a stepper motor with up to 2 Amps, and an Arduino board for automating tasks. The speed can be varied from 0 to 300 RPM, and is displayed on a 3-digit seven segment display module. The design was conceived to have the least amount of complex mechanical elements as possible, however, two special non trivial steps

Automatic candy sorter

Arduino candy sorter

Built by Willem Pennings from the Netherlands, this color candy sorting machine is robust and beautifully designed. It uses an Arduino controller, stepper motors, an RGB color sensor and several 3D-printed parts to perform sorting of colorful candies like M&M and Skittles. It can sort a 300 gram bag of mixed M&M in approximately 2-3 minutes. Posted below is a video showing the machine in action. The machine is able to sort M&M’s and Skittles by colour by performing optical measurements using the RGB sensor. It can be modified to sort any type of coloured object, as long as the individual pieces

DIY Arduino Pong Game

DIY Pong game using Arduino

Nick from educ8s.tv shows in the following video tutorial how to build a pong game using Arduino Uno, a 0.95″ SSD1331 driven SPI color OLED display, and some tact switches and jumper wires. You can play against the Arduino that controls the green paddle. Each time a player scores, the score is displayed on the screen. Posted below is the complete video tutorial.
