Solderless prototyping kit with a breadboard 3.3V/5V power module, 830-point breadboard, jumpers and common IC's for rapid bench testing and classroom labs - just BYO development board!





The seven band graphic equalizer IC ( MSGEQ7 ) is a CMOS chip that divides the audio spectrum into seven bands. 63Hz, 160Hz, 400Hz, 1kHz, 2.5kHz, 6.25kHz and 16kHz. The seven frequencies are peak detected and multiplexed to the output to provide a DC representation of the amplitude of each band. No external components are needed to select the filter responses. Only an off chip resistor and capacitor are needed to select the on chip clock oscillator frequency. The filter center frequencies track this frequency.

Check-in with your plant friends, this sensor is great for detecting soil moisture levels!
