BENCH / 07PCB & hardware

Small boards, useful jobs.

Small circuits and control boards from the bench—quick, practical builds rather than full write-ups.

FM Transmitter

BOARD / 01

FM Transmitter

Captures audio with a microphone and transmits it wirelessly over FM. Built for the Communication System Fundamentals course project.

MOSFET Switch

BOARD / 02

MOSFET Switch

Used to control a high-power pump wired to a weight-scale system — lets a small control signal safely switch a heavy load.

Arduino Nano Servo / Robot Arm Driver

BOARD / 03

Arduino Nano Servo / Robot Arm Driver

Drives a robotic arm using a variable resistor, making it easy to test manual positioning and servo response.

ESP32 12V Control Board

BOARD / 04

ESP32 12V Control Board

Controls an old RGB LED strip after its original controller was lost — Wi-Fi lets me set colors and effects directly.

Weight Scale (Auto Water Dispenser)

BOARD / 05

Weight Scale (Auto Water Dispenser)

A load-sensing water dispenser that pours precise volumes on demand. Full write-up, test data, video, and code live in the Smart Water Dispenser project.
