In this project, we will learn How to design an Accelerometer and Relay based Hand Gesture Controlled Wireless Home Automation System with AVR ATmega32 microcontroller using 433MHz RF. Here, we will use different hand gestures as input signal to control the appliances i.e 2 bulbs and 2 fans. Also, we will display the status of
In this project, we will learn How to design a Password Protected BT136 Triac based Keypad Controlled Wireless Home Appliances System with AVR ATmega32 microcontroller using 433MHz RF Part-I. Here, we will use the 4X4 keypad as the input device to enter the password and to control the appliances i.e 2 bulbs and 2 fans.
