Wireless weather station u sing Arduino Dear friends welcome back! Today we are going to build a wireless weather station project using Arduino.Without any further delay, let’s get started! A Wireless Weather Station with a big 3.2” Color TFT display. The project is up and running,and it displays the current date and time, the indoor temperature and humidity, and the outdoor temperature and humidity. The readings of the outdoor sensor are updated every second in order to demonstrate that we have a reliable communication link established with the transmitter which is outside at a distance of 5m. The readings of the indoor sensor are updated once every minute. The heart of the project is the fast Arduino Due, there is no flickering of the screen when the values are updated. Let’s now see the transmitter. The transmitter is much simpler. It consists of an Arduino Nano, a DHT22 sensor and the NRF24L01 wireless transceiver module. The transmitter reads the temperature and ...
Agribot – Smartphone Controlled Agricultural Robot Struggling to take care of your garden and wish that someone else did it for you? Well, this project is here to save your day! Meet Agribot: a smart robot that monitors the moisture level of the soil and waters it wherever the level is low! We’re going to modify the 4-wheel drive robot that we previously made in one of our blog to make the agribot. Click on the link below for finding out how to make the 4-wheel drive robot. Ready to make automate gardening? Let’s begin! Components for this project: Chassis Motor clamp Servo motor Servo horn Soil moisture sensor DC water pump Pipe Ice cream stick Cable tie Li-po battery Relay spacers Jumper cables PET bottle E vive Dabble PictoBlox Nuts and bolts Connections: Procedure: Let's begin by setting the servo angle. We will set the angle to 90° using evive’s menu. Connect the Servo to servo Channel 1. Next, from the menu, select Controls, then s...
