Here’s a design circuit of phone message flasher, an alternative way to get alarmed when there is an incoming call. This is the figure of the circuit. When the phone rings, high line voltage will be detected by A differential amplifier with hysteresis (Q2, Q3, and Q1). This action will turn on multi vibrator Q5/Q6, [...]
This is a simple circuit. Music can change the LED light level gamut.
Operation of this circuit is a circuit op amp IC1 / 1-IC1 / 5 compared to the characteristics of the circuit voltage.It has one pin acts as a voltage reference pin.That the pressure from the supply voltage and divide between R1 and R7 [...]
This the Tone Generator circuit that interesting because of can control the sound has with the light. By use the integrated circuit NE555 be pillar equipment , which perform produce sound frequency in model Astable Multi vibrator or pulse generator. And use 25 ohm small-sized loudspeakers. For the equipment detects the light. I uses LDR [...]
