Description: This circuit was developed in response to requests from visitors of this website for a timer that can emit a beep after one, two, three minutes, and so on, for jogging purposes. As illustrated in the circuit diagram, SW1 is a single-pole, nine-way rotary switch. In position 1, the piezo sounder emits three short beeps every minute. In position 2, the same occurs after 2 minutes, and this continues, reaching a maximum interval of 9 minutes in position 9.
The circuit utilizes a single-pole, nine-way rotary switch (SW1) to select the desired timing interval for the piezo sounder. Each position on the switch corresponds to a specific time delay, allowing the user to choose between one and nine minutes. The timing mechanism can be implemented using a combination of resistors, capacitors, and a timer IC, such as the 555 timer, configured in astable or monostable mode depending on the desired functionality.
In the astable configuration, the timer can continuously generate a square wave output, which can be adjusted by changing the resistor and capacitor values to set the beep interval. If a monostable configuration is preferred, the timer can be triggered by the rotary switch, and it will generate a single output pulse that corresponds to the selected time interval. The piezo sounder then emits a series of beeps, with the frequency and duration of the beeps being determined by the output from the timer circuit.
To enhance usability, a simple LED indicator can be added to visually confirm the selected position of the rotary switch. The circuit can be powered by a standard battery or DC power supply, ensuring portability for jogging or outdoor activities. Overall, this timer circuit serves as a practical solution for users looking to maintain a specific jogging pace with audible feedback.This circuit was developed since a number of visitors of this website requested a timer capable of emitting a beep after one, two, three minutes and so on, for jogging purposes. As shown in the Circuit diagram, SW1 is a 1 pole 9 ways Rotary Switch. Setting the switch in position 1, the Piezo sounder emits three short beeps every minute. In positio n 2 the same thing happens after 2 minutes, and so on, reaching a maximum interval of 9 minutes in position 9.
