Pac-man Pac-man Pac-man! Hahaa! If any of you knows what I am talking about, then you must be old enough to know such an old-fashion arcade game, just like me XD (NO OFFENSE). In fact, I started to play those classic Japanese game since I was a little boy, and right now I still feel interesting about it.

Combining Arduino and other shield modules, we make a mobile phone named Arduino Phone. Meanwhile, we printed a shell for it with the 3D printer. Although it’s not such fine as you think, even a little bit clunky, it’s still very cool. That is the point this is a cell phone made by ourselves.

In this project we are going to make Clapper circuit using the concept of ADC (Analog to Digital Conversion) in ARDUINO UNO. We are going to use a MIC and Uno to sense the sound and trigger a response. This Clap ON Clap OFF switch basically turns ON or OFF the device, by using the clap sound, as switch

Here a tone generator project is developed using Arduino Uno. A few number of buttons are interfaced with the UNO and each button generates different intensity of tone. The frequency of tone generated by the UNO is same at every internal. It’s the intensity of the sound which changes with each press.

In this arduino based project we are going to interface a 5 RGB (Red Green Blue) LEDs with Arduino Uno. These LEDs are connected in parallel for reducing PIN usage of Uno. Check out the complete tutorial here.

Water level controllers are useful devices. In this water level indicator and controller project we are going to use an Arduino board and ultrasonic sensor to measure the water level in a tank. We will also start the water pump automatically when water level goes low below a certain preset level.

In this project, we have built an Arduino based heartbeat monitor which counts the number of heartbeats in a minute. Here we have used a heartbeat sensor module which senses the heartbeat upon putting a finger on the sensor.

The same is also true for keeping items cool – it can be wasteful to run a whole fridge just to make yoghurt – but with a temperature controller, the principle is the same. Instead of activating a heating element, you’ll be activating the plug on a mini-fridge or other cooling element, like a Peltier (thermoelectric cooler) – and of course, the logic will be reversed.

In this project we are going to interface a ROTARY ENCODER with ARDUINO. ARDUINO UNO is an ATMEGA controller based development board designed for electronic engineers and hobbyists. In ARDUINO we have 20 I/O pins, so we can program 20 pins of UNO to be used as either input or output.

Today I decided i wanted to build an alarm for my room, when I searched online all door alarms used the PIR sensor, unfortunately mine was faulty.

and that"s when I decided to build my own alarm using an ultrasonic sensor (HC-SR04),and I found out it was really simple.
