Memory Buttons for Height adjustable Desk

thingiverse

Hi, this is a 3D Model to add memory buttons to a height adjustable desk. Most of them can only drive up/down and not to a certain point, thats why i made these. You need an esp8266, 2 channel relais, ultrasonic sensor (HC-SR04) and 5 times a 6x6x5 push button. The circuit diagram isnt that interesting, if you dont know anything about programming you need to solder these together: - Pin 1 = 13; - Pin 2 = 4; - Pin 3 = 0, - Pin Up = 5; - Pin Down = 14; - Pin MoveUp = 2; - Pin MoveDown = 12; - Pin Trigger = 15; - Pin Echo = 16; if you use other Pins, watchout wich of them are used by the ESP for boot, some of them cant be used. The Programm safes the memorized heights in the "EEPROM", so even after shutting of they are still there. If you want it, write me a DM. It took me around 10 hours so it would be nice to gift me a cafe :) paypal.me/streicherlein Its pretty packed in the case, so it can be hard to fit everything. I assembled and soldered everything outside and then slowly moved it in. The Buttons should get connected to Ground if pushed. If you want it built for you, i sell one for around 100€ with everything. Otherwise, have fun building :) Other than that, have fun buiding.
