Jogging Timer

This circuit was developed in response to requests from visitors for a timer that can emit a beep after intervals of one, two, three minutes, and so forth, suitable for jogging purposes. As illustrated in the circuit diagram, SW1 is a single-pole nine-way rotary switch. When the switch is set to position 1, the piezo sounder emits three short beeps every minute. In position 2, the same occurs after two minutes, and this pattern continues up to a maximum interval of nine minutes in position 9.

The timer circuit utilizes a rotary switch (SW1) to select the desired timing interval. The switch has nine distinct positions, each corresponding to a specific time delay before the piezo sounder emits a series of beeps. The circuit is designed to provide auditory feedback to the user, which can be particularly beneficial during jogging or exercise routines, allowing them to maintain pace or track elapsed time without needing to check a watch or timer.

The piezo sounder is an efficient and compact component that converts electrical signals into sound. The circuit may include a timing mechanism, such as a 555 timer IC configured in astable or monostable mode, to generate the precise timing intervals. Capacitors and resistors are likely used in conjunction with the timer IC to set the timing characteristics, determining how long the circuit waits before activating the sounder.

In practical terms, when the user turns the rotary switch to the desired position, the circuit is activated, and the timing sequence begins. The output from the timer triggers the piezo sounder to produce a series of beeps, providing an audible cue at the set intervals. The design is user-friendly, allowing individuals to easily adjust their timing preferences based on their exercise routines. This circuit can be further enhanced with additional features, such as LED indicators or a more complex timing mechanism, to provide greater functionality and versatility for users.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. 🔗 External reference
