Black Water Tank
Budget: $30 – $250 USD
I have a working Arduino project that has 4 sensor’s they read the liquid level of a tank. I have 4 LEDS of different colors that light up with the volume in the tank. I need a Bluetooth app for my Android Samsun S10 that shows the 4 lights and associated levels. I'm using an HM-10 Bluetooth LE module and an Uno R3 for hardware.
