Crazy Dripper (CIR376E)
This is a nice prank you can do with your friends! A dripping which mimics a leak and disturbs those who want to sleep, but which "hides" itself when it is sought. This device will disturb everyone!
Timed Vox (ART430E)
A vox circuit is an interesting resource for those who want an automatic monitoring of what is happening in a place under surveillance. The Vox is a circuit control that turns on the recorder as soon as the microphone picks up a sound above a certain level. Thus, the recorder will only be turned on when people in a room start the conversation.
Shadow Alarm with the 741 IC (ART429E)
The circuit we present is that of an alarm of lack of light, ie a circuit that produces an audible signal on a speaker when a sensor is no longer illuminated.
Moisture Alarm with the 741 IC (ART428E)
This circuit triggers when the humidity detected by a sensor causes its resistance to decrease, triggering the oscillator. Them it emits a sound in a speaker.
Temperature Alarm (ART427E)
It is basically the same circuit of the previous assembly with the difference that replacing the LDR we use as sensor an NTC. This component reduces its resistance with the elevation of the temperature which means that it is a temperature sensor.
Relay Logic Functions (ART426E)
Contrary to what many claim (with total ignorance about the subject), the teaching of digital electronics, logic and Boolean Algebra is more than ever fundamental to being able to work with microcontrollers. With the availability of 5 V relays (which can be powered by TTL sources) and even cheap 6 and 12 V relays, these components can be used in teaching, experimentation and even practical purposes in the elaboration of logical functions. In this article, we will see how this can be done.
