Thanks for the quick response alec_t
I was already considering the op amp circuit and glad you suggested what i was thinking. However, my electronic knowledge is only basic so i wil have to revert to some reference books for me to make a schematic of what you suggested!
Also, would it be...
Thanks for the response Mike ML.
I was looking to use a Bi-color LED for the indicator.
The lower range resistance input is 0 - 6 Ohms - this should turn the LED red.
The mid range resistance input is >6 to <9 Ohms - this should turn the LED green.
The upper range resistance input is...
Can anyone suggest a suitable electronic circuit for the below application.
0-6 ohm input switches on a Red LED
7-9 ohm input switches on a Green LED indication
10 to >100 ohm switches on a Red LED indication
Power supply needs to 9V cells only
LED type would be ideal as Bi-color LED...
