Solar Tracker-Arduino

This is an Arduino Uno Based solar Tracker- it uses 90% 3d printed parts with a 20x20 aluminum extrusion frame.

you will need:

2 micro servos

1 stepper - 28-byj48

1- 300 mm gt2 belt

1 Arduino uno

1- board from the gerber file

3 - photo sensors with appropriate resistors to get the values to 500 in the Arduino code

an assortment of m3 & m4 hardware and t nuts

2 m6 x 15mm bolts

2 skateboard bearings

1- 5/16 (8mm) x 1.5'" (38 mm) bolt

an assortment of wire (20AWG)

a crimp tool for JST terminal ends

5-2 pin JST ends

2-3 pin JST connectors

2 - micro limit switches (buy the ones with the cables and then depin the one side and attach a two pin in place of the three pin with the common and NO on the limit switch)

1 95x95 mm solar panel

**code will be updated in the future current version at time of posting is Version .7

– updates will include:

• removing all the serial commands as they were for debugging
• adding in a section for ease of changing certain parameters such as limits for angles and delay between searches
• adding in sleep function as it will currently just continually search for the sun
• adding in a homing function for morning alignment and a night-time detection system

any other features feel free to ask but I am usually very busy so I cannot guarantee the requests can be implemented in a timely manner.
