Hi! Nice project.One question: I need the smallest range i can get when i'm transmitting with this mini fm transmitter. If i don't solder the antenna to the circuit, could i get that? Thanks!!
Nice project!Is there a way to make more faces? How do i code them?Thanks!
Hi! You need to look for the datasheet of that volume controller. I'm sure that is disposed in two rows of three pins, right? If that's the case, i think you can connect the volume controller with one row of three pins like i do.
Hi SirCooksalot.The pot adjusts the signal voltage that enters into the circuit. In other words, adjusts the volume.The 2-pin is the power and the 4-pin is the input+output. You can see i put the names on it.
Hi RobotsMaking.Commonly in the diagrams the squares means the GROUND. You can see in the electrolitic capacitor you have the "-" sign with the square ones.
The pot adjusts the volume. In the lay out says what are the pins for. You just need to rotate 180 degrees! The 2 pin are the power input and the 4 pin are for input and output signal!Cheers.

Really nice proyect! It worked. I've used 9v but hasn't checked other voltages. I leave you guys here a photo of the circuit and the lay out i've made (the terminals of the trimpot are not placed in the same place as the lay out but i've adapted it).
