Project Statement
Design circuit to control RC-Car5 separate receivers
○ Forward, Reverse, Left, Center and Right○ Left and Right need to latch
Receivers triggered by a laser○ Up to 3 stories away

Step 1: Motor Control
H-Bridge CircuitNPN and PNP
transistors○ Allows for “flipping”
of poles needed to get forward and reverse

Motor Control Testing of H-Bridge With proper Voltages applied
(equivalent of 3AA batteries)Could not read the 3V needed
to get to motorAdjusted Resistance values,
different combinations of NPN and PNP transistors○ Still no luck
After research found a Specialized IC○ Able to run on supplied voltage

Forward and Reverse
Controlling the H-Bridge2 light controlled voltage
dividers ○ Fed into inverters ○ Used voltage buffers to
ensure H-Bridge chip receives digital high or low
Included a potentiometer ○ Able to adjust sensitivity of
voltage divider dependent on given ambient light

Steering Control
Originally tried with SR latchesRan into Problem with not being able to
apply a third position○ SR latch only have a “Set” and “Reset”
Ended up using a manipulation of the circuit from Lab 9 The laser controlled light

Steering Control Cont. Video shows what
discussed in previous slide
Both lights off show centered car
Lights corresponding to Left and Right directions
To implement this in circuit• We had a left over
Opto-Coupler from another project
• Used to interpret on and off of SCR

Schematic
Wanted to further and implement our designCreated schematic
○ Created layout through Dip-Trace (One member familiar with program already)

Layout
Once Schematic createdCan create the
corresponding layout pattern
Can move the different parts to a desired location○ Allowing PCB to
fit within the RC-Car

All together Sent needed
files to Advanced Circuits for fabrication
Received fabricated PCB Friday, May 3rd
Assembled/soldered and implemented into car
Completed PCB

Testing
Initial testingForward/Reverse
○ Functioned properlySteering
○ Worked but needed adjustments ○ While adjusting we fried our chip○ Tried to debug, no luck
Went with our plan BBuild on original breadboard
