hello everyone!
Urgently I need your help. Urgently I need to do Electronic Thermometer on the 7 Segment Indicator Without microprocessor and programing. And I need an electrical circuit (scheme) how to convert dc linear voltage (output of thermoresistor ) to square wave woltage?(I need an electrical circuit of '"woltage to Frequency"). If you can help me

Welcome to AAC!
Please post your question to ONLY ONE thread. Multiple threads will be deleted. This one has been moved to a more appropriate forum.

+1 for @joeyd999 's suggestion. Buy common anode displays, either a multi-digit unit or several single digits, that will be sufficiently bright at 8mA current (page 8 of the datasheet joey referenced).

Good luck!
