Answer the questions to narrow down what might be wrong with your robot:
http://tkcbot.strikingly.com/

Does the red LED light on the L298 motor controller (the digital clutch) come on?
Start by clicking in the box below
No?
Click here, then right arrow key
Yes?
Click here, then
right arrow key
Check these things:
Are the batteries fully into the holders?
Is the switch on?
Do the red and black leads from the batteries go into the correct terminals on the L298N motor controller (digital clutch)?
Are the batteries between 1.4 and 1.7 volts?
Are the batteries in the correct orientation?
Does the red/green power LED on the Arduino (computer brains) come on?
Navigate through this Prezi
by clicking on
the yes and no buttons
or by using the
left and right arrow keys
Press the right arrow key to begin
No?
Click here, then
right arrow key
Yes?
Click here, then right arrow key
Check this things on your robot:
or
Check these things on your robot:
Are the power wires correct?
Do you have the correct voltage?
5 volts
3.3-3.6 volts
Does the green/red LED on the Arduino blink fast and then slow and then fast again?
Do both motors spin twice?
Yes?
Click here, then right arrow key
No?
Click here, then
right arrow key
Voltage is too low
Arduino has the program loaded
Arduino is defective: swap it
Loading a program on your Arduino
Install Arduino IDE
program on your computer
Go to http://www.mrelliott.info
and get the program
myBTRv7.ino
(myBlueToothRobot
verion 7)
Set the IDE to talk to your type of Arduino
Plug in your Arduino to the USB port on your computer
Check the Arduino is recognised
Look under port to see a new listing like:
com4, ttyUSBO, or ttyACMO
If it is not listed:
Install ch341ser drivers
or
try a known good Arduino
Compile and upload MyBTRv7
Success!
(When you push the reset button on the Arduino)
Check these things on your robot:
No?
Click here, then
right arrow key
Yes?
Click here, then right arrow key
or
Do both motors spin forward then back?
No?
Click here, then
right arrow key
(When you push the reset button on the Arduino)
Check these things on your robot:
Yes?
Click here, then right arrow key
Check you have the four-wire bundle connected
Check the motor wires are connected to the L298N motor controller
(the digital clutch)
Test the motor controller by using a male/female jumper wire to connect 5v terminal to in1, in2, in3 and then in4
Test the motor by putting three or four batteries together and connecting them to the motor wires to see if the motor will spin
No?
Click here, then
right arrow key
Yes?
Click here, then right arrow key
Check these things on your robot:
Do you have the red and black motor wires backwards?
Do you have the four-wire bundle plugged in backwards?
You are ready to
test your Bluetooth!
Is the red LED on the Bluetooh on and flashing quickly?
No?
Click here, then
right arrow key
Check these things on your robot:
Check the path of the 3.3 volt (3.3v) and ground (gnd) wires to the Bluetooth chip
Is the Bluetooth chip in backwards?
Test the Bluetooth chip in a working robot
Yes?
Click here, then right arrow key
Can you see your robot by scanning from within Bluetooth settings on your Phone?
No?
Click here, then
right arrow key
Check these things on your robot:
Do you have the right Bluetooth chip (Apple or Android)?
Try a working Bluetooth chip from another robot
Yes?
Click here, then right arrow key
(or try unpairing and then re-scanning)
Can you connect from within the Blueterm+ (or LightBlue Explorer) app?
No?
Click here, then
right arrow key
Check these things on your robot:
Test the Bluetooth chip in working robot
Borrow the Bluetooth chip from a working robot
Try a different phone
Yes?
Click here, then right arrow key
When you punch in numbers into the app does the robot respond telling your what key you pressed?
No?
Click here, then
right arrow key
Check these things on your robot:
Check the path of the yellow and white wires on the robot
Borrow the Bluetooth chip from a working robot
Test the Bluetooth chip in working robot
Yes?
Click here, then right arrow key
Congradulations!
You should now have a working remote control robot :)

My
Robot

(press play)
Do you have the four-wire cable plugged into the outer row of pins?
Or
Does your robot frequently disconnect?
No?
Click here, then
right arrow key
Yes?
Click here, then right arrow key
You may need to add an extra voltage regulator to give a more stable voltage for the Bluetooth
Error!
Make sure your Bluetooth chip is unplugged while you upload
Are you using the
right Bluetooth chip?
Look for the MAC numuber
(the digital network licence plate)
for your Bluetooth chip
