Hi,
I Have Bluetooth Headset, for power up the Headset, I Have to transfer volts from the Battery+ to the microcontroller(Transfer volts from Pad "X" to Pad "Y"(SMD PCB)) I Mean, when 555 pulse for 5 seconds, its do that thing...... I Have circuit that should do this, but its not working..... How can I Do that?? Thanks... |
