Description
This kit uses a thermistor to measure the temperature which is then displayed on an LED scale. A PIC micro-controller, pre-programmed with special software, is used to process the output of the thermistor and light the relevant LEDs.
The thermometer has two temperature ranges. One designed for indoor use and the other for outdoor use (selected by a wire link). The temperature is displayed every 10 seconds or can be displayed on demand by adding either a normally open / normally closed push button switch.

Q:
Hi Is it possible for the Red LED's to be on all the time? We would power from a seperate poer supply.
A:
Hi, The program on the chip tells it to display the temperature for a few seconds, then to turn off and wait for 10 seconds and repeat. If you add a switch you are able to turn the chip off and on again which resets it to showing the temperature. If you used a combination of components that acted as a switch turning on and off quickly then the thermometer would constantly show the temperature.
