Hi,
I've created a circuit to flash 1 LED using transistor and capacitor. Here is the circuit that I've created, the only thing I saw with the LED is when the first time I connect the battery the LED lit up and it fade away, it does not go through the cycle of lit up and dim continously. Can anybody help and advice me me what is the problem with the circuit ?
The component I'm using
1. 9v battery
2. Transistor NPN MPSA42 (the datasheet is attached with this port)
3. 100uF capacitor
4. 5mm LED (Red)
Thanks for your help.
Cheers
