• The thermistor value is read and then converted to Celsius temperature by the formula and dis-
played on the LCD1602.
• The set threshold is also displayed on the LCD.
• If the current temperature is greater than the threshold, the buzzer will sound an alarm.
4.6.4 6.4 Reversing Aid
With the development of science and technology, a lot of high-tech products have been installed in cars, among which
