README
README.mdUniversal motor PID speed regulator for bench drill.
ATMEGA 328 based DC motor electronic regulator.
It uses pms67/PID library (https://github.com/pms67/PID)
Hardware design
- A potentiometer is used at input to select desired speed.
- Actual speed is measured and sent to controller
- ATmega microcontroller compute resulting PWM signal
- A MOSFET modulates MOTOR DC voltage.
- Switching frequency is 32KHz.
Software design
- Potentiometer position is read via ADC3 (setpoint)
- Speed sensor connected to INT0 and measured by counting timer2 ticks (measurement)
- Sampling rate is set to 0.1 Sec and call to PIDController_Update()
- Output is used to control motor voltage (PWM)
- Calculations are done in floating point and normalized to one.

Questions
How big is the PID Controller PCB?
It measures 99.7 × 69.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PID Controller use?
52 parts, built around the BAT54, BC639, BC640 and RHRP15120. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the PID Controller KiCad files?
From the glecuy/PID_Controller repository on GitHub, at the commit this page was made from: the board is Hardware/PidController/PidController.kicad_pcb and its schematic Hardware/PidController/PidController.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PID Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask glecuy before reusing the design.
