Ok, so I am making an RC boat following the instruction of this video (https://www.youtube.com/watch?v=fWDTAmIqlUQ). However this part confuses me

. More specifically how am I supposed ot go about connecting the motor driver to a battery and then connect that said battery into the Arduino. Anyone how I'm supposed to proceed with this or any other alternatives. Please and Thank you

Do not supply power to the servo from the Arduino. Find a suitable power supply.

The 8vdc power supply in your image probably has an RCA jack for the Arduino Power Jack and a second set of wires going to the L298. You can see a similar drawing on this web site

Do you have a soldering iron?
Do you have wire strippers?
Do you have electrical tape?

I expect problems with your radio, here is why:
Power Stability Issues with RF24 Radio Modules

As described in the RF24 Common Issues Guide, radio modules, especially the PA+LNA versions, are highly reliant on a stable power source. The 3.3V output from Arduino is not stable enough for these modules in many applications. While they may work with an inadequate power supply, you may experience lost packets or reduced reception compared to modules powered by a more stable source.

Symptoms of Power Issues:

  • Radio module performance may improve when touched, indicating power stability issues.
  • These issues are often caused by the absence of a capacitor, a common cost-saving omission by some manufacturers.

Temporary Patch :

  • Add Capacitors: Place capacitors close to the VCC and GND pins of the radio module. A 10uF capacitor is usually sufficient, but the exact value can depend on your circuit layout.
  • Use Low ESR Capacitors: Capacitors with low Equivalent Series Resistance (ESR) are recommended, as they provide better power stability and performance.

Adding the appropriate capacitors can greatly improve the reliability of your RF24 module by ensuring a stable power supply, thus minimizing packet loss and enhancing overall performance. A separate power supply for the radios is the best solution.

There is no link to the part being used so I took a SWAG:

I think you posted to the wrong topic. Did you read post #1?

The radio was part of the frizzy. I assumed he was planning on using it as he was talking remote control. This was to forestall future problems.

I do not normally watch videos.
