Ice warning and light reminder electronic project

A very simple ice warning and lights reminder electronic project can be implemented using the circuit diagram .

This device will tell a driver if his lights should be on and will warn him if the outside temperature is nearing zero by lighting a LED and sounding a buzzer .
Using the VR1 you can adjusts sensitivity for temperature and using VR2 you can adjust sensitivity for the light . Both thermistor and LDR should be well protected . More high gain NPN transistors will work for this electronic project .

For this electronic project you can use BC108 type transistor or some other NPN high gain transistor .
This ice warning and lights reminder electronic project must be powered from a 12 volt DC power supply circuit .
