    Hello! Thank you very much for your videos. I am Brazilian and I love your projects. Thanks for sharing the gerber. It's very nice. I am 54 years old, but I feel like a child with his projects. Obrigado

    I have made my own using these components.
    # 433mhz RF module for wireless communication,
    # two arduino nano,
    # one HC-SR04 ultrasonic sensor to check water level in the tank,
    # one relay to actuate motor,
    # 16x2 lcd (i2c) it shows the percentage of water in the tank,
    # one touch sensor to turn-on motor, # rgb led to indicate water level,
    # two Hi-link SMPS to power both setups one in the tank and another near motor or wherever u want to place in the house....
    #when i touch the surface of touch sensor motor turns-on when water level reaches 100% then motor turns-off automatically. I have been using it since last two months and its working perfectly. I also made it for my friend he is satisfied with that too

    Hi! I would need a PCB that is not 7-channel but 10-channel. I think two pieces of ULN2003 would be needed on the PCB. How and with what program could I modify the original plan?
