Voltage measured on 7805 regulator is about 4.95V.
Voltage measured on 555 ic :
- on pin 3: [3.69V]
- on pin 7: [4.04V]
Green ( charging LED) is always on and red (dumping LED) is off.
When i press the charging puss buton, nothing happens.
When i press the dumping button, the red LED(dumping LED) turns on, and turns off when i release the button. So if i hold the dumping button pressed, the red dumping led start to blink ( the blinking looks interrupted, uneven), but the Green charging led don't turn off (it stays on but the light diminishes).
