    I would like to say thank you for this great tutorial ... I proudly made it as project for the end of this semester .. It is working very well and it is rising hair very well also .. I've made some simple modifications like using a rubber belt instead of the vinyl and a Teflon tape wrapped on the polyamide roller instead of a Teflon roller .. This was cheaper ... At the end I want to say really thank you for this

    can i use 2 hc-05 ? instead of hc-05 and hc-06 ?and what is the level of T ? 3.3 or 5 V ?

    I don't want to boost it since the Rx of the hc-05 has a 3.3V level ... I want instead to apply voltage division if it is 5V Thank you for your fast reply Mr
