When the stored values and current value match, the buzzer for the alarm will be triggered. Other circuits modulate the carrier frequency, superimposing speech and music on it. For example, an FM radio broadcaster may use a precision oscillator set to 94.1 MHz, the station’s carrier frequency. These values are continuously compared with the present time. &0183 &32 Radio transmitters and receivers use oscillators to generate high-frequency signals. The values entered as alarm are stored in the EEPROM of the Arduino. you can use Apples Shortcuts app to set a BBC radio station to play via BBC. Once the alarm time is entered, set button is pressed and the alarm is set. App alarms are difficult to make reliable and we feel we should be focusing. News/Talk 660 KSKY Dallas: The Broadcast Clock Creator has been the perfect tool for training our board operators. Once the hours of the alarm is set, we must press the next button to go to minutes tab.Īgain increment button is pressed to change the minutes. &0183 &32 As seen in Radio INK, and Radio Magazine: The Broadcast Clock Creator is in use at CBS Radio News, KGO, WBAP, WGN, Fox News, The Voice of America, Sky News, The BBC and Arbitron. The increment button must be pressed must be pressed to change the hours.Īs the clock is in 24 hour format, the hours will be incremented between 0 and 23. It’ll go to alarm mode and asks for hours with current time being displayed. In order to set the alarm, we press the set button.
#How to create a radio program clock code
The code for Arduino is uploaded and the LCD displays the current date and time. The working of the project is explained below.Īll the connections are made as per the shown circuit diagram. The aim of this project is to create a real time clock along with an alarm feature. A buzzer is connected to pin 11 of Arduino that acts as an alarm. These buttons are connected to pins 8, 9 and 10 of Arduino. RS, E, D4, D5, D6 and D7 (Pins 4, 6, 11, 12, 13 and 14) of LCD are connected to pins 2, 3, 4, 5, 6 and 7 of Arduino. 6 pins of LCD must be connected to Arduino. Both these pins of RTC are pulled high using 10KΩ resistors.Īn LCD is used to display the clock. These are connected to respective SDA and SCL pins of RTC. Analog pins 4 and 5 will act as SDA (Serial Data) and SCL (Serial Clock). There are two pins on Arduino for I2C communication. I2C protocol is a method of communication between a faster device (Microcontroller or Arduino in this case) in master mode and a slower device (RTC) in slave mode.

The communication between microcontroller and RTC IC DS1307 is serial I2C bidirectional bus. Aģ2.768 KHz crystal is connected to the oscillator terminal of DS1307 for 1 Hz oscillations.
A 3V backup battery must be connected to the RTC so that the IC can automatically switch to the backup supply in case of power failure. The clock can operate in either 12 hour with AM/PM indication or 24 hour format. The clock function provides seconds, minutes and hours while the calendar function provides day, date, month and year values.
