This is a year delayed because the light sensor misbehaves in outdoor light and only works reliably indoors.
I thought of a solution using two sensors to compare a target to a sample weed instead of the trouble I am having with mathematically determining colours of weeds (which frustratingly vary depending on brightness and quality of lighting).
Dual sensors would work because an indoor lit and outdoor lit target are compared to a real sample indoor lit or outdoor lit sample rather than compared to a mathematical model of what is that weed colour. Is it yellow? is no longer relevant. All that matters is: Is it the same relative to the sample weed under the same light condition as the target weed.
This circuit works, but the sensor is not distinguishing weeds from grass in outdoor light.
So I have not included the computer program to flash the Arduino, yet:
This is the circuit only showing the alternate solenoid driver part. Add the sensor from the previous schematic.
