Troubleshooting Workshop at SRHS 5/11

Notes:

• Good battery vs bad battery; put it under load before testing voltage.


• 5V should be at pin #7


• "Verify" in BASCOM compares code on the chip to code in the program.


• SW1 shoud be on. SW2 is only for Hunter Bots


• Some students put infrared emitters on bot by mistake instead of LEDs. You can still see the emitters using a digital/cell phone camera.


• Need alligator clip for one side of multimeter to clip onto VR for ground. This makes testing much easier.


• Test servo pulse at JP 8 & JP 9 on pin #1


• Use hip holder (with slots rather than holes) as a connector


• Solder sensors to jumpers before inserting - taken care of if chip holder is used.


• Diagnostics: Push and hold SW1 then turn on SW2 then release SW1 for diagnostics mode.


• Test Sensors first w/o servos connected (to avoid wasting


• Need to use heat shrink
