Replace LEDs and phototransistor on LSA with IR sensors.
gautam-dev-maker opened this issue · comments
The current design of LSA is very prone to ambient light and often cause inconvenience in line following.
Possible solution is to test TCRT-5000 for ambience interference.
If it proves to be better than current design, we can easily modify our LSA design to include it.
As discussed previously
- Try different IR based Transmitter Receiver Pairs ( PTH and SMD ) from various LAMI vendors on a perfboard
- Test on the current SRA Board and check readings on ADC lines for line-following with and without a buffer amplifier IC
- If buffer amplifier is needed, find a dealer (online or offline) if HEX IC is available ( 5 -6 gates in one IC ) for the facility of more than 4 sensor pairs if desired
- Redesign LSA PCB prototype for the best available combinations
- Test PCB Prototype
- Final Order
Hard deadline - 5th November
@marck3131 proceed with this issue and update ASAP
@marck3131 Please post the perfboard testing results here ASAP
ping @marck3131. Please post the results here as well.
5 IR sensors were tested on perfboard with resistors 4.7k E and 100 E , with gpio pin numbers 32, 34, 35, 36, 39
Tested Line following too with the same ...
@marck3131 Please put the images, sensor placement and line-following demo video with new config here as well for reference.
@dhairyashah1 we can close this issue as this has been implemented in the design.
