This circuit works as I want. When the piezo disc is press the LED lights according to how hard the piezo is press. Good..but... the piezo needs to be
press really hard to make it work. Could you please suggest how to make it more sensitive? (I will prefer not to add any IC or any additional transistor. Diodes, capacitor and resistor are OK to be added.)
Thanks,
