AT the end -> A very trivial but important lesson – something that we all assume we know theoretically but might fail to implement practically !!.
- My first step was to test the module , the connections were straight forward and the results were good.
- After that i connected the pins from arduino to the level shifter like this –
|Arduino Pin||4-bit Level Shifter Pin|
There are two GND pins on the level shifter and both are internally connected so connecting one is enough.
- Then i connected the pins from the Level shifter to wires coming from the RC like this –
|Level shifter Pin||PCB wire|
- Final looks –
- After that…
