In this project, we are going to do a step-by-step guide to building a temperature alarm circuit whereby when it hits the specified temperature, it would start to trigger a buzzer. The entire circuit will be centered around an LM324 operational amplifier and 4093 NAND gate IC. This digital electronics project teaches you how to create a temperature-based alert system, useful in many applications, such as temperature-sensitive areas where an audible alert can help signal high temperatures. Components Required for Temperature Alarm Circuit To build this digital electronics project, you’ll…
