What components are needed for the self made servo control board

It seems that HC595 is required, which is a data distributor, and a microcontroller with multiple PWM outputs is also required. The most important thing is these two, and the others are power supplies and other devices. I've seen circuits and source programs on the Internet, so you should be able to find them if you look carefully.

Hello, the single-chip microcomputer cannot directly control the servo. Here's why:

1: The output current of the IO port of the single-chip microcomputer is too low to drive the motor at full power.

2: Some single-chip microcomputers can be increased with the output current after pulling, but the servo is an inductive load, which will produce greater interference during operation, affecting the normal operation of the single-chip microcomputer or surrounding components.

Suggestion: The most secure method is to drive the optocoupler with the output of the microcontroller, the optocoupler drives the MOS tube, and the MOS tube drives the servo. If the servo power is small, it can be driven with a triode. If the number of servos is large or the power is large, the power supply should be isolated.

Hope it helps, thank you.

Not necessarily, the level should be compatible, it is best to supply power independently, and it must be co-grounded.

1. First look at the power supply to the control board is a switching power supply or an ordinary power supply with a transformer, if it is a switching power supply, it will be directly connected to 220V, if it is a transformer, the transformer must be replaced with a 220V output and the original transformer output voltage is the same.

2. Change the power supply of the control board to see how much V the original fan is, if it is 380V, you don't need to change it, if it is 220V, open it after the change, and use the multimeter to measure the three power cords to see which two are connected to 220V. 3. If there is no 380V voltage when repairing, use the method used when testing the 220V machine.

vs and gnd are + and , respectively. GND means grounding. You need to connect six 5V stepper motors, depending on how big the current of the stepper motor is, to choose the power supply, for example, the current of each stepper motor is 600mA, you can choose the power supply of 4A5V.

If your six servos don't work at the same time, 3A is enough.

It is not difficult to control the servo, but the difficulty of multi-channel servo control is to generate stable multi-channel PWM signals at the same time. You only need to lead out all the IO ports of the MCU, and all the outlets are connected with a 1K resistor.

I've done it myself, and this is a diagram, and you can understand it by looking at the diagram.

The control board is also a kind of circuit board, although its scope of application is not as wide as the circuit board, but it is more intelligent and automated than the ordinary circuit board. To put it simply, a circuit board that can play a control role can be called a control board. From the manufacturer's automated production equipment to the small toy remote control car for children, the control board is used inside.

Lead out all the IO ports of the single-chip microcomputer, lead out the outlets, and string all the 1K resistors, and it's over, isn't this it?

It seems that HC595 is needed, which is the data Jingshi Inspectorate device, and it also needs a single-chip microcomputer with multiple PWM output and limb. The most important thing is these two, and the others are power supplies and other devices. I've seen circuits and source programs on the Internet, so you should be able to find them if you look carefully.

The specifics are not very clear.

Something like this:

The motor is connected to the angle sensor by means of a reduction gear.

The pulse received by the servo corresponds to an angle, and this angle is compared with the angle of the angle sensor to determine whether to add positive voltage or reverse voltage to the motor, so that the motor can rotate forward and reverse.

The shaft on which the servo ends up exposed is directly connected to the angle sensor.

Reduction gears are generally multi-stage, one-level deceleration, and multiples generally range from tens to hundreds.

There are two main functions of reduction gears:1Reduce the error There may be a few errors on the motor, and only a few degrees of error after passing through the gear; 2.The output torque is increased, and the force is increased by a factor of how many times the speed decreases under the ideal state of p=f·v.

What the angle sensor actually gets is a sliding rheostat that converts the angle into a voltage <>
