Hello All, My solar dual axis tracker works well under artificial light and follows torch light perfectly, BUT as soon as I put it outside in the sun( no clouds) ,it goes to it's start position and ignores the sun. I put opaque plastic caps (ex pir sensors) on the 4 LDR's, to soften the sun ligh…

[image] amspen: All values show 1023 in the sun Sounds like a problem in the wiring or choice of components (the LDRs and associated resistors). The wiring diagram in the original Instructables is nearly uninterpretable, and the 10K value for the resistors in the voltage dividers is probably…

[image] amspen: // LDR pin connections // name = analogpin; int ldrlt = 0; //LDR top left int ldrrt = 1; //LDR top right int ldrld = 2; //LDR down left int ldrrd = 3; //ldr down right pin :face_with_raised_eyebrow:assignment questionable ???

The numbers represent analog's eg A0,A1,A2,A3 for 0,1,2,3

Use a local RTC to turn the solar tracker simply.

Hi, @amspen Can you please post some images of your tracker, in particular the LDR sensor assembly. Can you please post a copy of your circuit, a picture of a hand drawn circuit in jpg, png? Hand drawn and photographed is perfectly acceptable. Please include ALL hardware, power supplies, compone…

Format your code using Tools/Auto Format in the future. The sun is several orders of magnitude stronger than whatever you used, you will need to adjust sensitivity.

Hello Tom I got the code from : https://www.instructables.com/Arduino-Solar-Tracker/ I set the Serial.begin to 115200 , as you suggest I don't know how to put :Serial.print statements in the code.
