1.17.12 Square Bot Assembled, programmed and test run, Logic Probe Circuit

For the beginning of the lab week, I assembled the Square Bot chassis.  The rechargeable battery was added, the program was uploaded, and I test ran the Square Bot.  I made some adjustments to the motor's screws and it ran fine.

Today, I set up a circuit for a logic probe using a transistor 3904.

 After adding a resistor (150KOhm) in parallel to the 360 Ohm resistor and connecting it to the base of the transistor, the LED was brighter.

 I went to the soldiering room to soldier the Logic Probe onto a PCB.
