The complete Schematic diagram for theArduino Based Spy Bugis shown below. The brain of the project is the Arduino Nano that you can see in the schematic. The main component of this project is theMAX9814which is a low-cost, high-performance microphone amplifier withautomatic gain control(AGC)...
set all eeprom to FF then you save at address = address +1 . When you reset the program looks for the first FF then sets the address 1 less and reads the Led. Then after next button press save at address = address +1. With a Nano you now get 11000+ days – around 30 + years....
Connecting the I2C LCD is very easy as you can see in the wiring diagram below. You can check out my detailed tutorial below for more information.How to control a character I2C LCD with Arduino. If you want to use a standard non-I2C LCD instead, take a look at this article:How to u...
