An Arudino powered pong clock used the classic Pong video game to tell the time, and has multiple display modes to choose from. Arduino pong clock The 2 players automatically win and lose so their scores show the hours and minutes. It is based on a clock by Nick Hall. This is the 2nd version of my clock and now displays temperature in slide mode and also has a timer in normal mode. The 1st version can be found here Pong Clock Mk1 instructable The clock has lots of different display modes to choose from: Pong Clock, Large Digits,Time written in words, e.g. “Ten Past Twelve”, Time a ..read more

Dejan Nedelkovski from HowToMechatronics illustrates a DIY vending machine using Arduino platform. The vending machine features four discharging units controlled via four continuous rotation servo motors, a carrier system controlled via stepper motors, an LCD, four buttons for selecting an item and a coin detector. DIY vending machine using Arduino You can watch his build process in the following video ..read more

This Instructables describes how to build a complete WiFi enabled weather station using Arduino and ESP8266 along with a bunch of sensors that collect environment data like temperature, humidity, wind speed, pressure, UV level, and rain. Arduino powered WiFi weather station The location weather station is the most important part of installation. If weather station is located under a tree or an overhang, the rainfall data measured by the station will not be correct. If you place your weather station in an alley, you could very well get a wind tunnel effect on the anemometer, result ..read more

An Arduino powered midi controller project for music makers. This my first arduino (microcontroller) project. I want to learn arduino with a usefull and large project. I decided to make a midi DJ controller that have all the functions needed to be standalone to mix. Every kind of sensor (potentiometer, push button,…) can be learn independantly and I think the best way is to learn “how it works” and “how it is connected” for each sensor step by step. Midi controller using Arduino ..read more

A portable pocket Tetris project using ATTiny85 and SSD1306 based OLED screen by dombeef. Pocket Tetris project This project originally was meant as a fathers day gift for my tetris-loving father, and I felt like it should be available for others if they want to make a pretty small tetris clone. This was the smallest I could make it with a big enough battery and a thick durable 3d printed housing. I modified tetris code created by Andy Jackson to be used with 3 buttons, since his original code was made for the AttinyArcade platform that has 2 buttons ..read more

Here is a bluetooth enabled Arduino garbage monitoring device that indicates the level of the trash in the bin alerting everyone, with the use of a simple mobile app. This small home improvement has lead to a more efficient system. Arduino trash bin monitor ..read more

RyanM415 built an Teensy 3.6 powered car display using an on-board diagnostics (OBD-II) adapter from Freematics and a 7″ TFT LCD from Adafruit. The display has two pages: one shows off when the car is in drive and the other for when it is in reverse gear. During driving mode, it displays the RPM, MPH, engine load percentage, battery voltage, cabin temperature, and engine coolant temperature. And in reverse mode, the Arduino IDE compatible Teensy 3.6 reads an animated bitmap image of the car and displays it along with the readings from the backup sensors. Car OBD data ..read more

Andy Brown is fond of beers and he loves homebrewing. To automate the temperature control required for fermentation and conditioning process, he designed a process-controller based on Arduino processor that allows precise switching of three relays to control the heaters, fridge and fans that are the parts of the temperature controlling mechanism in his brew fridge. The controller also features a triac for phase-angle dimming that is helpful for proportional heater or fan control. The device connects to a host PC via USB. Find details here. Arduino Process Controller ..read more

Tecwyn Twmffat built an Arduino-based Cell Phone 4G Signal Booster. Arduino cellphone signal booster Living on an island in the middle of nowhere, mobile/cell phone reception can be rather intermittent and it seems that there is currently no reliable open source gadget that could help me solve this problem on my kind of budget. I do have the option of using ‘cable phone’ but being of a general ‘Pirate’ disposition I thought it would be a better idea to do all my phone calls, emails and data transactions by cell phone and save a whole bunch of dollars by not having to pay for land based ..read more

Amardes built an Arduino-powered relay controller that can be used to the sprinkler systems in your garden. It uses the DS3231 I2C precision RTC module with battery backup for time keeping. Arduino timer switch   ..read more
