So i've chosen to purchase a Wemos D1 R2 board in order that my old Arduino Uno R3 projects can get some new IoT features. However, even if my code is working in Uno perfectly, i want to test it using D1 before adding features. My problem is that, even if i have found tables showing differences between the 2 boards' pinouts, i cannot understand the correspondence between the pinouts.
So i am giving you the table below. Let's say i want to define echo and trigger pins for a sensor in my code. For example:
#define TRIGGER_PIN 4 #define ECHO_PIN 3
That would be pins D3 and D4 at my Uno. But i cannot understand which those pins would be in Wemos D1 R2. Also, my two boards can be seen below for comparison
