I'm trying to connect an IR sensor to an Adafruit Feather Huzzah microcontroller module without soldering the pins on. The sensor has a power supply of 5V which I have connected to the USB pin of the microcontroller as shown below. I don't have access yet to a breadboard but I want to try and get some data as soon as I can.
My first question is whether the electrical connections will work without soldering?
Secondly, am I using suitable cables for the connection to the sensor since although it goes all the way in, it is quite easy to pull out. This may be a problem since they may come out during application.
And finally, while writing this question, I found that the USB gets regulated down to 3.3 V so I need to use a power supply at 5 V. Is there a quick fix for this or will I have to just have to wait until the breadboard arrives and then connect it to a battery?
Also, what are these cables called?
