Description
With its low part count this easy build timer project makes a good introduction to electronics. The timer uses a resistor capacitor network to provide a time delay of between 1 second and 4 minutes, which is set by the PCB mount variable resistor. When the button is pressed the LED changes from red to green, then at the end of the time interval it turns red.

Q:
Hi,
Would it be ok to swap the switch with a tilt switch, mounted elsewhere? I would also use your coin cell battery.
Thanks
A:
Hi Simon,
Thank you for your email, that should be possible but you would have to do a bit of alteration on the circuit with flying leads and so on. You would need to make sure you solder the flying leads for mounting the tilt switch off of the board into the two tracked solder points on the board as well.
Best Regards
Cullen
