LED sound level indicator with your own hands!!! Everything great is simple!
Hello everyone! Today I will make a sound level indicator whose scale will consist of 24 LEDs! The schematic of the device is not complex and does not contain scant details.
The base of the sound indicator I made from copper wire. But I made steel wire guides to achieve the desired rigidity. I then soldered the LEDs and transistors onto these guides. To make this audio signal indicator I have used the KT3107, KT3102 and KT315 transistors. These are some of the most common transistors, but they can be replaced with more modern ones: the BC557 and the BC547, respectively.
This indicator does not need adjustment. If the circuit is assembled correctly, it works stably and reliably!
All details about the assembly and checking of this sound indicator can be seen in this video!
Everyone understands that for the channel to develop and the new videos to be of higher quality, and the experiments to be on a large scale, material investments and a lot of time are needed. We are limited by the economic circumstances that occur in our locality, we spend a lot of time on our main work, SO any help will be valuable, so the videos will come out more frequently and better. To support the channel in development, you can transfer any amount you consider necessary to the following requirements:
