Lab01: Using a Transistor to Control High Current Loads with an Arduino
Notes:
- Relays, transistors basically do the same thing: Switch.
- Relays uses magnetics to control switch. there’re two circuits.
- Transistors are faster.
Cautions:
- [ ] The polarity of diodes;
- [ ] µF=microFarad
- [ ] motor driver has to be soldered

Lab: DC Motor Control Using an H-Bridge
Question:
- how to understand “H-bridge”?
- why, in some conditions, the motor switches fast and unobvious, while some has a clear “deceleration-acceleration”process?
