Tracker control
Here is the tracker control system in its deployment configuration. Socket at right holds the Arduino Pro Mini clone (ATmega328 5V 16Mhz). Socket at left holds the A4988 Stepper Motor Driver Carrier. Single 2-pole screw terminal block, left rear, connects to the HOME sensor switch. The pair of 2-pole screw terminal blocks, left front, connect to the four leads of the stepper motor.
In the past, I've shied away from perf board in favour of making etched printed circuit boards. PCBs look so much neater, but, as I age, time becomes more precious.
I sucked it up and deployed on a perf board.
