DC motors are very fun to play with. They can be used to make small cars or other little inventions that need some sort of rotation. But there is a small problem with controlling them. They need lots of current. Arduino can't handle this amount of current so there is possibility of de...
Arduinos are limited in the current and voltage they can supply. A typical 5V Arduino can provide 5V and 3.3v at a maximum 40mA from a single pin. 40mA is the maximum and ideally the current draw should be kept to around 20mA. 20mA is fine for a LED but not so good for motors, ...
It is possible to modify the Servo library that comes with the Arduino IDE to use Timer 3 instead of Timer 1 with an ATmega32U4 based controller like the Romi 32U4. The modified Servo library does not interfere with Romi32U4Motors, making it possible to simultaneously control servos and the...
a sealed enclosure 194, fabricated from sheet metal in the embodiment, with carry handles 196 for carrying the flow meter 152 unit or box. In the embodiment, the enclosure 194 houses the battery, the stepper motor 182, and an electronic control system (not shown), based on Arduino technology...
it should be clearly understood that a variety of programmable microcontrollers can be substituted to achieve the same result. Other types of drive motors and steering motors other than servo-controlled motors could be used, such as stepper motors and microcontroller controlled motors. Therefore, the...
