The project sunshade is a program for the arduino computing-platform. The main purpose of this program is to open and close a big sunshade.
The required mechanical work to open and close the sunshade comes from a dc motor. This dc motor is directly conected to a transmission. Both devices are recycled from an old cordless screwdrive.
The h-bridge modul drives the motor.
For the controll interface a IR (infrared) modul is set up.
I still have a small doubt if it is working while the sunshade is closed, but I will figured it out later.
Like mention befor a arduino computing-platform is used for the program processing and I/O controlling job. Currently the Mega 2560 is in charge. But for later on it could be change to a Nano variant.
- For the electronic assembly a universal aluminum housing is being considered.
- How to mount the complete assembly to the sunshade is currently being explored.
But we are happy to announce that we were able to win an welding expert for this project.
To finde out if the approach, to recycle the devices of an old cordless screwdrive for I executed a simple POC :-).

Motor values when no mechanical resistant is conected - no sunshade Voltage 11.28 V 11.27 V 11.24 V Current 1.70 A 1.73 A 1.77 A
Motor "anfahren" Voltage 5.00 V Current 11.25 A
Motot with sunshade connected Voltage 7.00 V - 8.00 V Current 9.00 A max 9.00 - 10.00 A
Motor stops becouse oc mecanical blocade Voltag 3.10 V 3.60 V Current 13.00 A - 14.00 A
