HOMEMADE oscillator for BUZZER Easy to MAKE. In this video TUTORIAL of easy electronic projects we are going to make a homemade tool or homemade invention to be able to activate the buzzers or BUZZERS in a homemade way since in many occasions it is not possible to put them to work if it is not with a high frequency power supply, We have them in two ways: the active buzzers that come with a small oscillator and the passive buzzers that need a small oscillator electronic circuit, which is what we are going to do today, we are going to use a recycled transistor from a PC power supply, d13009k is a transistor NPN type of power, we are going to use a coil recycled from a power supply of an LCD television that is no longer used, a 1.5v cell or battery, a push button that we can recycle from an electronic card or electronic device or household appliance in disuse, a 1k electrical resistor, brown, black red gold, two crocodile or alligator clips, one black and one red, and the buzzers or BUZZER that we are going to be able to test, some electrical wire, tin, tin or soldering iron and a lot of imagination, at the end From the video I leave you the electrical diagram so that you can assemble it without problem in an easy and fast way, if you like the video do not forget to leave your like thank you ..
