Leo listened. He heard the clean hum of a clock line, then the ugly buzz of a shorted capacitor. “You built this?”

The masterpiece was the ESR Meter for capacitor health. After a week of tweaking op-amp offsets and averaging 100 samples, she could spot a bulging electrolytic before it blew a power supply. arduino test equipment projects

Then came the Signal Generator . With a few lines of code and an RC filter, her Arduino spat out sine, square, and triangle waves from 1Hz to 8kHz. It wasn’t lab-grade, but it was hers . She paired it with a Frequency Counter using the same board’s timers, and for the first time, she could watch a 555 timer drift in real time. Leo listened

Marisol’s workbench had always been a graveyard of good intentions. Dusty multimeters, a soldering iron with a bent tip, and a scope that hadn’t booted since the Obama administration. She was a repair tech by trade, but lately, every fix felt like a guess. After a week of tweaking op-amp offsets and

Six months later, a younger tech named Leo wandered into her shop. He held a dead drone controller. “I don’t have a signal tracer,” he said.

That changed on a Tuesday, when a small blue box arrived: an Arduino Uno.
