A deaf visual doorbell circuit

The circuit with the original m rJ bamboo is designed similarly. It includes a secondary disk that functions as a floodlight. A grass-flow filter is incorporated for a light input. An electric connection is established with a door button (S1), which activates the doorbell. The circuit utilizes a radio frequency (RF) component, specifically a tube (Tl) with a frequency of 5011z, to control the on and off states of a semiconductor (Si). The circuit operates with a monostable configuration, which generates a pulse determined to be 15 milliseconds. The output pulse is used to stabilize the oscillator, which controls the drive tube. Additionally, there is a light-emitting diode (LED) that is connected in series with a bulb, which flashes in response to the activation of the doorbell button. The circuit is designed to operate with a power supply of approximately 10W.

The circuit described includes several key components that work together to create a functional doorbell system. The initial stage involves the activation of a door button (S1), which serves as the user interface for triggering the doorbell. Upon pressing the button, a signal is sent to a monostable multivibrator circuit, which generates a precise output pulse. This pulse duration is critical, set at 15 milliseconds, allowing for a stable operation of the subsequent components.

The RF tube (Tl) operates at a frequency of 5011z, which is essential for the wireless transmission and reception of the doorbell signal. The semiconductor (Si) plays a pivotal role in switching the circuit states, enabling the RF tube to turn on and off as required by the system's operation.

A light-emitting diode (LED) is integrated into the circuit as an indicator, illuminating in response to the doorbell activation. The LED is connected in series with a bulb to provide visual feedback when the doorbell is pressed. This configuration ensures that the user can easily identify when the doorbell is active.

The circuit's power requirements are approximately 10W, which is sufficient to drive the light and the RF components effectively. Additionally, the design includes protective measures, such as diodes, to prevent back EMF and ensure stable operation. Overall, this doorbell circuit combines simplicity with functionality, making it an effective solution for signaling at entryways. Circuit with the original m rJ bamboo is also exactly the same way.
