To create a new script on the Arduino IDE, select File -> New and save it with the name and location of your choice.Īfter creating a new script, replace the content in the window with the code you have copied from the link in step 4. ![]() Follow the link below and copy the contents of the page into a new script on the Arduino IDE: This project requires code which is not provided by the Arduino software. Using the USB cable, plug your Arduino into your computer. If you haven’t already, please go to the Arduino website and download the “Arduino IDE” for either Windows or Mac, and then install the software on your computer.Ĭonnect the circuit as shown in the diagram below: Now, compile the program and upload it to your Arduino board.If you and your group have any questions or get stuck as you work through this in-class exercise, please ask the instructor for assistance. Int ldrlt = A0 //LDR top left - BOTTOM LEFT dvert || dvert > tol)Įlse if (avt dhoriz || dhoriz > tol) // check if the diffirence is in the tolerance else change horizontal angleĪt last, we have added the delay of (dtime). Ldrrd is for Down Right // LDR pin connections Servo Vertical Limit When Signal is High is set to 60 degrees.Īlso, Servo Vertical Limit when the Signal value is low is set to 1 degree. This is the Servo Configuration for Vertical Servo Horizontal Limit When Signal is High is set to 175 degrees.Īgain, Servo Horizontal Limit when the Signal value is low is set to 5 degrees. The Servo Horizontal is set to 180 degrees. #Include is used to include a servo header library file. Programming Arduino for Dual Axis Solar Tracker Project ![]() Finally, Connect the Bottom Right Voltage Divider Point of LDR to the A3 pin of the Arduino.Similarly, Top Right LDR Voltage Divider Point to the A2 pin.Again, Connect Top Left LDR voltage Divider Point to A0 pin of the Arduino.Connect bottom left LDR voltage Divider point to A1 pin of Arduino.Let’s connect the wiper pin of the potentiometer-1 one to the Analog Pin A4 and A5 to another wiper pin of Potentiometer-2.Now, connect all LDRs from one terminal to the 5-volt and other terminals to the Ground Through 10k-ohm resistors.Connect one terminal of both potentiometers to the Ground and the Other end terminals of both potentiometers to the VCC 5 volt.Again, connect the Signal pin of the horizontal Servo Motor to the Digital Pin No.Now, connect the Signal pin of the Vertical Servo Motor to the Digital Pin No.Similarly, Connect the GND pin of the Both Horizontal and Vertical Servo motor to the Ground. ![]()
