Will this circuit work?

Other Hardware General Electronics
1

I would like to make something with these components but I am not sure if this setup will work, I haven't bought anything so I am open for all suggestions and the wires on the right that don't go anywhere will be connected to some kind of power supply. I read something about "common ground" so I tried to implement it but to be honest I have no idea what I am doing.

The used components are:

  • Arduino Uno
  • SparkFun Logic Level Converter
  • Bi-Directional - SparkFun WiFi Module ESP8266
  • SparkFun Force Sensitive Resistor 0.5
  • A yet to determine DC motor

I have provided a schematic of the circuit
It would be awesome if you guys could help me.

The Force Sensing Resistors are not connected properly. They need to be part of a resistor voltage divider along with a fixed resistor.

So you mean like this?

Yes, and I would power the FSR with the Uno 5V not the (noisy) motor supply.

Hi,
And I would start to draw circuit diagrams, rather than use Fritzy images.

CAD or a picture of a hand drawn circuit in jpg, png will give more info, including labeling the transistor ins, E,B,C and including your power supplies.

Thanks for all the help and suggestions now I can start building
