Temperature measured on seven segment display by LM35 and Arduino (Part 1 of 2)
We had already seen the circuit to get the temperature using LM35, temperature sensor, through arduino uno in my previous blog. There, temperature is printed on the serial monitor of arduino. Here, we are designing a circuit in which temperature will be printed on a five digit common cathode seven segment display.
Circuit is done as shown in the following diagram. Temperature sensor is connected to arduino uno. Arduino board will measure the temperature and temperature will be displayed in a five digit common cathode seven segment display through 74HC595 shift register ICs.
Before starting the circuit, you must read my previous blogs on :
- Temperature measurement using LM35 and arduino uno.
- Circuit to control a 74HC595 using arduino mega.
- Cascade operation of two 74HC595 ICs using arduino uno.
- Circuit to control a cluster of 8 common cathode seven segment displays using 74HC595 and arduino uno.
