Hi everybody.
I've made the circuit with 555 which is in the HS1101 datasheet from Humirel.
The problem is the fluctuation in Frequency which is too much.
Any suggestion or any other circuit which has frequency output?
Thanks a lot in advance.
The datasheet : HS1101LF
For oscillator try 74HCT14 it gives good frequency,me I am doing the same but the problem I have I want to know how comparing resistive changes of a sensor an the frequency from an oscillator but which is input in the microcontroller on the other input ;mean while I have two differents inputs.
