4.6.3 6.3 High Temperature Alarm
Next, we will make a high temperature alarm device using thermistor, push button, potentiometer and LCD. The
LCD1602 shows the temperature detected by the thermistor and the high temperature threshold value, which can be ad-
justed using a potentiometer. The threshold value is stored on EEPROM at the same time, so if the current temperature
exceeds the threshold value, the buzzer will sound.
Required Components
In this project, we need the following components.
