ESPHome is a simple yet powerful system that allows users to control ESP boards using YAML configuration files. It allows users to quickly and easily build custom firmware for sensors and devices without any programming skills.
Today, we are going to build an Arduino based Touch Screen Door Lock System that contains a 2.4" TFT Screen for entering the Personal Identification Number (PIN) and for visual display of the entered PIN.
Whether it is IoT, M2M, or Industry 4.0, LoRa is one of the most popular wireless communication medium. LoRa is getting popular day by day and there are many LoRaWAN networks all around. It consumes very low power and can communicate over a long-range.
There are various wireless communication technologies used in building IoT applications and RF (Radio Frequency) is one of them. nRF24L01 is a single-chip radio transceiver module that operates on 2.4 - 2.5 GHz (ISM band).
Robots are used in many sectors like construction, military, manufacturing, assembling, etc. Robots can be autonomous or semi-autonomous. Autonomous robots do not require any human intervention and can act on their own according to the situation.
