I am new to the electronics world and have a question.
I am designing a circuit that has a sensor and bluetooth transmitter. The sensor outputs voltages from 0-4.5V. The transmitter cannot have input voltages higher than 5V. Thus, I want to add something into my circuit such that voltages of 0-5V pass through, but voltages higher than 5V are limited to 5V. This will protect my transmitter from voltage spikes.
Can anyone tell me how to do this? Diode? Zener diode? something else?
Thanks in advance for your help!
