Arduino Plant Irrigation System

This interesting arduino based project automatically provides water to your plants and keep you updated by sending message to your cell phone.

Here we have used a soil moisture sensor, which checks the moisture level in the soil and if moisture level is low then Arduino switches On a water pump to provide water to the plant. Water pump gets automatically off when system finds enough moisture in the soil. Whenever system switched On or off the pump, a message is sent to the user via GSM module, updating the status of water pump and soil moisture. You can see the working of this project in below video:

This system could be very effective and useful to automate irrigation in Farms, gardens, home etc. It is completely automated and there is no need for any human intervention. To DIY this project check out this tutorial on CircuitDigest.com

DIY Arduino based Robotic Arm

This DIY tutorial talks about creating a simple Arduino based Robotic Arm. This complete robotic arm will be designed from scratch. Entire process of construction has been explained in detail below. The arm has been built with cardboards and the individual parts have been locked to servo motors. Arduino Uno is programmed to control servo motors. Servos are serving as joints of Robotic arm here. Have a look to final setup of entire project.

Low torque servo motors are used here but you can use more powerful servos to pick heavy object. The whole process has been well demonstrated in the below video.
