Hi can anyone help me in building a circuit for a training aid.
It must have a start switch that after pressed gives an audible beep and shows a red led, after a 1 minute delay an audible beep signalling the start of a 7sec delay to end with start of a 4 sec green led(red off) followed back to the red led and restarts the initial beep and 1 min count.
switch -beep- 1min red led - audible beep - 7sec - 4 sec green led (red off) - back to start beep and 1min red led on
It would be a huge advantage if the timings could be programmable.
This product is the closest available to purchase but not quite what I need.
