wow great work friend, I am also working on that, but I do not use 4 servos, I only use 2 and 2 gears 2 (they are 2 gears on each side of the black parts that close) close more than your mask, I recommend That, the truth is that I would like you to help me since I do not have much knowledge in electronics, just and used a button to activate the mechanism, but I want to use sensors, maybe with this recommendation it will make it easier, since you only need to connect 2 servos and 2 sensors in the Arduino nano, so you save the need to design another circuit, I just need help in knowing how to program the servos with the sensors
my setup only uses the 2 servo's and its funny you say that as after speaking to other spidey's around november last year ive been working on a mark2 mask using gears instead.wow great work friend, I am also working on that, but I do not use 4 servos, I only use 2 and 2 gears 2 (they are 2 gears on each side of the black parts that close) close more than your mask, I recommend That, the truth is that I would like you to help me since I do not have much knowledge in electronics, just and used a button to activate the mechanism, but I want to use sensors, maybe with this recommendation it will make it easier, since you only need to connect 2 servos and 2 sensors in the Arduino nano, so you save the need to design another circuit, I just need help in knowing how to program the servos with the sensors
