Resistance issue #10

Adrien5353 commented 2 years ago

Hi Seems to have a resistance issue Tested with 220ohms and 9kohms, seems to have some spurious signal, so, after few seconds the movement is stopped. With 220 ohms it always happens, with 9k it happens sometimes. Changing resistance solve the issue, for couple of days (as it has burned) Which one do you use please?

Edit Finally found. My issue is not from résistance but from Reed switchs. Changed them and all works well Thx for your work <3

Sorry the late reply! Basically its a pull down resistor. This is usually done with switches to stop random noise flucuations triggering a switch. More details here https://www.instructables.com/Understanding-the-Pull-up-Resistor-With-Arduino/ I basically read guides like this and did something similar. I can't remember the exact resistance but that example uses 10k
