Strip Board Circuit Help! #6

Open Dancopy opened 3 years ago

Dancopy commented 3 years ago

I couldn't understand the circuit on the strip board; connection tracks, component nomenclature and incomprehensible design, etc. Is it possible, please, a schematic in pdf? Thanks

It is the schematic as laid out in the data sheet. https://www.sparkfun.com/datasheets/Components/General/MSGEQ7.pdf Double it for the two channels, just connect both strobe pins and both reset pins together.

The stereo pot to adjust the gain rarely has the same values. You can either make the adjustments in software or as shown in this example in hardware. You take the 100 KOhm Stereo pot and add to each channel in series a 22 KOhm pot. This way you can adjust the L and R channel to have the same resistance.

Good luck Gyro
