We will connectSNS-DS18B20-MAXIMtoESP32-EVBvia the UEXT connector using I2C pullup resistor. UEXT pin.1 3.3V is connected to the red wire, UEXT pin.2 GND is connected to the black wire and UEXT pin.5 (GPIO16) is connected to the yellow wire. import machine, onewire, ds18x20, time...
I want to understand how to implement at least some sort of digital communication in embedded system - because it is fundamental to any project where interfacing between two or more digital components is required (e.g. interfacing between microprocessor and TFT (or LCD) display). ...
..I connect it on I2C interface with an Arduino Nano. Stop right there. The Arduino Nano is probably the only model that is NOT suitable for any of the HomeBrew/DIY projects. The onboard USB serial chip is hardwired to the same pins we need for the AUX port, and it simply will...
This idea revolves around a small remote-controlled boat fitted with sensors to check water quality. You will guide the boat around different parts of a lake or river, measuring pH, turbidity, and more. The microcontroller can send readings to a base station onshore. This lets you see real-...
