Yes, it will work but check signal pins before you attach Bluetooth and motors.

Adjust potential meter of sensor according to your range and check the range by keeping your hand in front of sensor.

Male to male and female to male

@@SimpleCircuitsOfficialthank you !

Matchbox

Yes, you can use it according to formula. That time I only have 100k so I used two 100k resistors to make them 50k resistor.

Check the ultrasonic sensor wiring with the arduino and for more you can join telegram group for more live discussion.

See the port you are using

@@SimpleCircuitsOfficial ok thanks

Set the potential meter on the back of lcd. (BLUE COLOR)

At the place of 'init' use 'begin'.

Arduino IDE

Yes

Please reply 🙏

Please tell your question correctly

App ki code me jo lcd me 4 solt show kar ta tha me usko 6 kardu to us code me koi problem hoga kya

bro what about code?? it's really working

Ya that's why he sad project is working.

Is it hardware fault?

Check connections

Arduino

@@SimpleCircuitsOfficial With?

Arduino bro Arduino

@@SimpleCircuitsOfficial I knew bruhh.. How should I express you my POV!

One end of adapter to arduino and other end at socket.

Yes, but code will change
