This alarm systems circuit is designed using the UM3561 integrated circuit which can be used in various alarm systems using few electronic parts.
This UM3561 alarm systems circuit project require few electronic parts and is powered from a simple 3 volts dc power supply.
T1 transistor enables supply to the sound generator IC when the base current starts following trough it .
This audio distribution circuit project is designed using the TL064 or TL06 operational amplifiers and some other common electronic parts.
This audio distribution circuit presented in this schematic is based on an TL06 (you can use TL064 ) and it’s very useful in signal distribution .
This 32 watt audio amplifier circuit using TDA2050 is designed using the TDA2050 integrated circuit a very simple high fidelity audio power amplifier, intended for use as an audio class AB audio amplifier.
The 32 watt audio amplifier circuit based on TDA2050 can be used both HiFi and high class TV sets.
