RFID Door Lock System Using ESP-Rainmaker

We tried to make the most versatile RFID door lock system, in which we never need to worry about reprogramming it if we want to add or remove cards, or even if we lost the card we can still open the door using the rainmaker application. So program it once and use it for a lifetime.

all in one home automation project-2

All In One Home Automation Project 4Lights And 1Fan(without IR Sensor & Remote) (Recommended for Home Assistant)

In this project you can control 4 AC appliances and Speed of 1 ceiling fan using Home Assistant dashboard and manual switches, fan regulator. This Same project will also work with other IoT Platforms like, Blynk, Arduino IoT Cloud, Firebase Realtime database, AWS etc. For controlling the speed of the fan we have used capacitive dimming method. And also you can get real time feedback of Switches, Fan regulator & IR Remote on your IoT Platform.

PAM8403 5V Two-channel Stereo Mini Class-D 3W+3W Audio Amplifier Original Quality

The PAM8403 is a 3W, class-D audio amplifier. It offers low THD+N, allowing it to achieve high-quality sound reproduction. The new filterless architecture allows the device to drive the speaker directly, requiring no low-pass output filters, thus saving system cost and PCB area.

With the same numbers of external components, the efficiency of the PAM8403 is much better than that of Class-AB cousins. It can extend the battery life, which makes it well-suited for portable applications.

Universal TTL Auto Programmer

This single programmer will help you to program multiple microcontroller chips/boards. This board got dedicated slots for programming

  • ESP32 Cam Board
  • ESP32/ESP8266 Chip 
  • Arduino Pro mini

Along with that, it also got a dedicated pinout of a regular TTL programmer using which you can program almost all the microcontroller chips. This simplifies the programming of the Microcontroller significantly since no manual reset and boot mode selection is needed when using with a common USB to serial interface. It’s a must have tool for all IOT and Electronics Engineers.
