4 channel relay optocoupler (only using 3)
128x64 IIC LED screen
x2 momentary switches
I build V8 swapped s10's
I have a transmission (4l60e) that uses 3 solenoids to command a gear.
solenoid A, solenoid B, and TCC are the wire names
simply put by choosing a combination of on or off to each wire you command gears 1-4
park,netural, and drive are all handled by a physical cable.
zero chance of shifting into park or reverse.
i want to use uno r3 with a led screen that displays what gear im in. output to the 3 wires will be handled by a optocoupler relay board.
shifter will be two momentary buttons on the steering wheel one for upshift and one for downshift. works just like a video game. 1,2,3,4 or 4,3,2,1
im not intrested in rpm limits or being told about how downshifting too early could be bad. this truck will live on the track only.
i need code made and a simple schematic of what pins to follow. maybe working out bugs if i have any.
i have provided the gear on/off patterns
