![]() The sketch begins by importing LiquidCrystal.h and MyTones.h libraries, so you can reference various items from these later on in the code. Arduino IDE 1.6.4 is used to compile and upload the program (called sketch). The program is written in Arduino programming language. The program implements all required functionalities including handling user inputs with the help of switching interface. SoftwareĬircuit operation is done using the software program (tone_generator.ino) loaded into the internal memory of Arduino Uno R3. Connect piezo buzzer’s negative terminal to the collector of T1 and positive terminal to 9V battery. To integrate the piezo buzzer (PZ1) through transistor T1, connect the base of the transistor to Arduino’s pin 8 through R7. Connect the anode (positive) of LED1 to pin 6 of Arduino Uno and cathode to ground through R8. Glowing of LED1 indicates that you are in Menu mode and the tone keys have been disabled. Also, connect it to pin 7 of the Arduino. Read/write (R/W) pin is connected to ground.Ĭonnect one terminal of menu switch S8 to 5V and the other terminal to ground through R10. Its pins D4, D5, D6 and D7, register select (RS) and enable (EN) are connected to pins 5, 4, 3, 2, 12 and 11, respectively, of the Arduino Uno R3 board. Pin 15 of LCD1 is connected to 5V power supply and pin 16 is connected to ground for backlight on the LCD screen. Resistor R11 connected at pin 3 of LCD1 is used as the contrast control of the screen. LCD screenĬonnect the LCD1 pins according to the circuit diagram shown in Fig. Change the frequency values or add additional switches to fully customise your project. The Arduino program (tone_generator.ino) defines the musical notes and frequencies associated with each tone key. Switches S3 through S7 are also connected to analogue pin A0 of Arduino Uno board in a similar manner. One terminal of switch S2 is connected to 5V supply through R1 and the other terminal to pin A0 of Board1. S1 is directly connected to 5V power supply. The resistors (R1 through R6) are placed in a sequential order, connecting each switch to 5V power supply. Tone key switches (S1 through S7) are connected using a resistor ladder. 2: Circuit diagram of the tone generator system It is based on Arduino Uno board (BOARD1), liquid crystal display (LCD1), transistor BC547 (T1), a buzzer (PZ1) and a few other components.

At about the 30 Hz mark, the ear can start to hear the frequencies, so direct frequencies can be used. Pure direct frequencies can help you heal, grow, and change.īelow 30 Hz, the ear can not hear, so Binaural or Isochronic Technology Is necessary. Every person, every animal, and every planet vibrate at its own rhythm. Everything in Existence has its own Frequency Signature. Listening to these frequency tracks can help us heal body and mind, sleep better, explore more spiritual and unknown energy area.įrequency offers professional frequency sessions designed for maximum results, especially multiple healing frequencies for creating positive shifts. Frequency is consist of several healing audio tracks, which have been produced by professional frequency generator technology.
