Hello. we are looking to prove a proof of concept. We want to open and close a door with a stepper motor and a Arduino. The idea is tha we need to have the door to be safe. How can we make the steper motor to stop if some one puts their hand between the door and the frame? we cannot use IR sensor or anything on the frame of the door. I was wondering if somehow we can read when the motor is bee...

Hello, I need help with the modulation of my transceiver. I want to create a new header file with Wireless Development Suite and paste it into my library. Since I'm still relatively new to programming, I'm not sure what steps I need to take in this regard. To what extent, for example, something has to change in my own code.
Project is to help me develop a board layout that connects a GPS and SD card modules directly to a ATMEGA328P. Then assist with the programming of the Arduino chip. This is a educational project for myself. I am looking to learn skills during the development process, so I would like to work closely, watch and ask questions. If you wish to work alone without questioning do not bid on this project....

Our current PCB is designed to control four strings of addressable Leds over WiFi using a NodeMCU ESP8266 V2. Works well, but could be better with a few changes. --- Revisions --- - It uses a logic level shifter to connect the 3.3 V ESP data ports to 5 V Leds. We found that there are two sizes of shifters and it is difficult to know what you will get when ordering. A second set of pin holes 2.54...
