Ultrasonic Wireless Water Level Indicator – Solar Powered
An ultrasonic water level controller is a device which can detect water levels in a tank without a physical contact and send the data to a distant LED indicator in a wireless GSM mode. In this post I will show how to construct a ultrasonic based solar powered wireless water level indicator using Arduino in […]
Wireless Thermometer Using 433 MHz RF Link Using Arduino
In this post I will show how to construct an Arduino based wireless thermometer which can monitor the room temperature and external ambient temperature. The data is transmitted and received via 433 MHz RF link. Using 433MHz RF Module and DHT11 Sensor The proposed project utilizes Arduino as brain and the heart as 433 MHz […]
Wireless Servo Motor Control Using 2.4 GHz communication link
In this post I will show how to construct a wireless servo motor circuit which can control 6 servo motors wirelessly on 2.4 GHz communication link. Introduction The project is divided into two parts: a transmitter with 6 potentiometers and a receiver circuit with 6 servo motors. The remote has 6 potentiometers to control 6 […]
Wireless Mobile Phone Charger Circuit
A wireless mobile phone battery charger is a device that charges a compatible cellphone or mobile phone placed close to it, through high frequency wireless current transfer, without any physical contact. In this post I have explained how to build a wireless cellphone battery charger circuit for facilitating a cordless cellphone charging without employing a […]
How to Make a Wireless Robotic Arm using Arduino
This robotic arm circuit which can be also implemented like a robotic crane, works using 6 servo motors and can be controlled through a microcontroller remote control, using an Arduino based 2.4 GHz communication link. Main Features When you are building something as sophisticated as a robotic arm, it must look modern and must include many […]
