Arduino voice recorder module | Electret microphone and sd card module
Hello viewers, in this video we will see how we can build Arduino based voice recorder module. We, can also playback at the same time. This requires interfacing sd card module with Arduino. The list of the components are as follows:
1. Electret microphone
2. 2N3940 NPN transistor
3. 0.1 uf capacitors x2
4. 10k resistor x4
5. 100k resistor
6. LEDs x2
7. 100 ohm resistors x2
8. push bottons x2
9. micro sd card module
