Rocket Brand Studios Tiny Tank

Assembly 8
  • Double check that you know which (2) red/black wires are from the switches and which (2) are from the motors. Loosely route these wires so they sorta point to where they will eventually connect. 
  • Pull the servo's wire forward and/or to where it will connect to your particular board
  • Mount your microcontroller board making sure you don't pinch any wires between the brass stand-offs and the board
The following instructions are for Tiny Tanks that will use the Arduino Nano the the Rocket Brand Undershield.
  • Connect the 2 pwr wires. Ground is on the bottom. If you are using (4) alkaline batteries, use the connection on the end of the board. If you are using rechargables, use the connections at the edge of the board. (See the instruction manual for more info)
  • Connect the 2 motor wires. It does not matter which way they go, you can determine the motors' direction during coding.
  • Connect the servo wire --Note, ground is closest to the edge of the board and the signal wire it closest to the chip
  • You may plug in your sharp sensor to one of the ADC inputs if you would like or you can wait and do this after the servo has been centered and the sensor bracket is attached.
  • I personally like to run a "big-ol" cap (capacitor) on my power lines. I have found that microcontrollers are much happier with this little "boost" of power when it need it (when motors kick in, etc) --If you see any "funny" behavior from your little bot, you may want to add this cap as shown in the pictures.
