This is how to make an RC car for around 40$(27$ w/ uno clone).

Step 1: Parts

1. An Arduino Uno(from Amazon), Micro, Mega, Duo, or Leonardo.($5.99 Uno clone)

2. Robot platform.

3. L298n Motor driver.

4. Hc-06 bluetooth module.

5. 9v battery.

6. 9v battery holder.

7.Android device.

Software:

Arduino IDE

Arduino Bluetooth RC Car

Step 2: Programing

Here is the code:

Step 3: App

The app is simple, UP, DOWN, RIGHT, LEFT, UPRIGHT etc. ,also a slider. Arduino Bluetooth RC Car website.

Requires Android

2.3.3 and up.

Step 4: Wiring

Wire the robot as above, then it should be ready.

Thank you for reading.

Have fun!

It runs for around 15 minutes, and the batteries can supply 300mah(nimh). Li-ion batteries voltage is to low, as it cuts out at about 7.5 volts.

I use two li-ion 4.2 6000mah plus a 9v battery. I power the arduino with the 9v and the motor shield with the 4.2v 6000mah batteries and no problems.actualy the arduino can handle 12v.

Hi!

Can you help me please? I have a problem with the overturning of the program. It's write:

avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00

avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x00

avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0x00

avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0x00

avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x00

avrdude: stk500_getsync() attempt 6 of 10: not in sync: resp=0x00

avrdude: stk500_getsync() attempt 7 of 10: not in sync: resp=0x00

avrdude: stk500_getsync() attempt 8 of 10: not in sync: resp=0x00

avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x00

avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x00

So I can't upload, it's a big problem.

Thanks for your help!

PS: Excuse me for the grammar, I'm french and my level englsih is low.

The wires of mounting must not be plugged in when you put the program on the Arduino board. I think that was the solution to my problem.

The wires must not be plugged in when you put the program on the Arduino board. For me it was that.

Tell me if it your problem :)
