3.3 volt power supply is one of the main issue when we use ESP8266 - 01 as a standalone board. The board runs in 3.3 voltage . More than this voltage, it may damage your board. In this tutorial I am going to show how to make a simple 3.3 volt regulator for your ESP8266 board. You can make this at a cost of 0.4$ (~20 rupees). There are also available some 3.3 volt power supply for purchase but there cost is more than this.
Let's make an all terrain remote controlled rover bot. This is a great starter project for hobbyists. In this tutorial I am showing how to make an all terrain robot using arduino with two mode of controlling, Using smartphone controlling and the other one is , using our own designed RF remote .it is more easy and flexible to use and also low cost. The total cost for making this robot is less than 60$.
Areas or fields of it's application(with the updated version 2.0)
- Disaster management.
- Spying agent for military purpose
- Rainwater drainage system cleaning robot
- Repairing of pipelines that human can't access
- In nuclear plant disasters

How much essential it is ,to make an efficient wireless remote controller for your projects like robots, RC cars, RC boats etc.. It is the remote controller which effects the whole performance. It is sure that a good remote controller can make your robot well functioning. In this post I am showing how to make a efficient, simple remote controller using an arduino and two joystick modules.

- The first wearable technology for blinds
- Using ultrasonic waves to detect the obstacles
- Notifying the user through vibrations/buzzer sound
Third eye for blinds is an innovation to help blind people to navigate with greater comfort, speed and confidence, while making use of ultrasonic waves to detect nearby obstacles and to notify the user through vibrations and beeps of a buzzer.
We designed a special wearable device based on the arduino which can be worn like a cloth for blinds. This device is equipped with five ultrasonic sensors, consisting of five modules which are connected to the different parts of the body. Among two for both shoulder, another two for both knees and one for the hand. Using the five ultrasonic sensors they can detect the objects in a five dimensional view around them and can easily travel anywhere. When the ultrasonic sensor detects obstacle the device will notify the user through vibrations and sound beeps. The intensity of vibration and rate of beeping increases with decrease in distance thus they can locate the exact position of the obstacles and this is a fully automated device.
