How to make blinking flash LED and beeping siren sound using 555 timer chip
A very simple electronic project for beginner how to make blinking flash LED and beeping siren sound using 555 timer chip. The speed of the flash and beep can be controlled using different capacitance value of the capacitor. The schematic is provided in the video and it's quite simple to follow and the video provide direction how to connect the pins of the 555 timer. Refer to the pinout configuration of the chip below of the 555 timer chip.
One simple circuit to step up voltage using LM2577 -Adj P+ chip. The schematic is from Texas Instrument and it works expected - and below is...
