Ardublock zero-based programming routines 2 PWM Dimming

PWM (Pulse-width modulation) pulse width modulationPWM is controlled using digital means to a means of the analog output. Using digital controlgenerates different duty cycle square wave (a constant switching between on and off signals) tocontrol the analog outputs. Generally port input voltage is only two 0V and 5V. If I want myoutput voltage of 3V how to do. . . Some students said that the series resistance, right, this methodis correct drops. But if I want to 1V, 3V, 3.5V, and so forth between changes in how to do it?Impossible to keep it switched resistor. In this case. . . You need to use a PWM. How he controlsit, the digital port for arduino LOW and HIGH voltage output only two switches, thecorresponding voltage is 0V and 5V output, we present the LOW is defined as 0, HIGH is definedas 1 to a second arduino 500 outputs a signal of 0 or 1. If this is all for a 500, it is a complete 5V, ifall is 0, that is 0V. If 010101010101 so that the output, just half and half, the output port on thefeeling is the voltage output of 2.5V. This is a screening of the film, and we reason, we have to seethe movie is not completely continuous, it is actually output 25 pictures per second, in this case isthe servant can not be seen to the naked eye, it looks like that is a continuous . PWM is the samereason, if you want different voltages between 0 and 1 on the control of the output of proportionalcontrol is ok ~ course. . . This is true there are still differences of continuous output, output perunit time of 0,1 signal, the more control the more accurate.


fl

In the following figure, the green line represents a cycle between, and its value is the reciprocal ofthe PWM frequency. In other words, if the arduino PWM frequency is 500Hz, then the periodbetween two green lines is two milliseconds. analogWrite () command can be controlled in therange of 0-255, analogWrite (255) indicates a 100% duty cycle (normally open), analogWrite(127) duty cycle of about 50% (half the time).

The experiment is controlled via a PWM LED lights brighten and then slowly let it slowly darken,so the cycle. Similarly, we still put bright LED module to the digital IO port pin 10, the followingis a wiring diagram:

Photoresistor (photovaristor) also known as light-sensitive resistor which is made of the use of thephotovoltaic effect of a resistance value changes with the intensity of incident light resistor;incident light intensity, the resistance decreases, the incident light is weak, the resistor increases.Light sensitive resistor is generally used for measurement, control and photoelectric conversion oflight (the change of the light is converted to electrical change).Photoresistor can be widely used in various light control circuit, such as lighting control,regulation and other occasions, also be used for light control switch.In this experiment we first conduct a relatively simple experiment using photoresistors

experimentsA position servo servo drive, mainly by the housing, a circuit board, coreless motors, gears and theposition detector of the composition. Its working principle is the microcontroller sends a signal tothe receiver or servos, which has an internal reference circuit, resulting in a period of 20ms, thewidth of 1.5ms reference signal will get the DC bias voltage and the potentiometer voltagecomparator, access differential voltage output. Judgment of the IC via the circuit board thedirection of rotation and then starts rotating non-core motor drive, the power transmitted throughthe reduction gear arm, and back to the signal from the position detector to determine whether thepositioning has been reached. For changing the angle and that require a control system can bemaintained. When the motor speed is constant, the reduction gear driven by cascading rotarypotentiometer so that the voltage difference is 0, the motor stops rotating. General steering angleof rotation range is 0 to 180 degrees.

There are many standard servos, but all the servos have an external three lines, respectively, withbrown, red, orange and three colors to distinguish, because servos different brands, colors willvary, brown is the ground wire, red for positive power supply line, orange for the signal lines.Angle of rotation of the servo by adjusting the PWM (pulse width modulation) signal duty cycleto be achieved, standard PWM (pulse width modulation) signal period is fixed at 20ms (50Hz), intheory, should be distributed at 1ms pulse width to between 2ms, but, in fact, be 0.5ms to 2.5mspulse width between pulse width and servo corner 0 ~ 180 correspond. It is worth noting theplace, because servos different brands, for the same signal, different brands of servo rotation anglewill be different.

Breadboard Jumper * a tieArduino control with steering in two ways, one is through the Arduino ordinary digital sensorinterface produce different duty cycle square wave, analog servo positioning generate a PWMsignal, the second is the direct use of Arduino comes Servo function steering control, this controlmethod has the advantage of programming, the disadvantage is only control two-way steering,because Arduino own function only use digital 9,10 interface. Arduino drive capability is limited,so when you need to control one or more servos require an external power supply.

A timer can be opened with the output timing, when this port goes low when you can readtiming The value of this time on time for this distance, only calculate the distance. This constantcycle of measurement, you can reach the value of the mobile measurement ~ ~

5 Module works:Only need Trig / TX pin input a high of more than 10US, the system may issue 8 40KHZultrasonic pulse, and then detect the echo signal. When the echo signal is detected, the modulealso for temperature measurement, and then the ranging result of the current temperaturecorrection, the corrected results by Echo / RX pin output. In this mode, the module into thedistance value is 340m / s when the time value of 2 times, a high level side output by Echo,according to the duration of this high value to calculate the distance. Ie, the distance values are:(High Time * 340m / s) / 2. Note: Because the distance value temperature correction has been, atthis time no longer according to the ambient temperature on the ultrasonic sound velocitycorrection, that no matter how much the temperature, velocity selection 340m / s can be.

With Arduino sensorexpansion board can be madeFor remote control and other interactive work. In addition the product in order to allow customersto more easily fit arduino expansion boards and other standard interfacesMouth, in the design of the X, Y, Z-axis circuit leads individually, you can use three pinARDUINO dedicated line directly into the expansion board for use. It is convenient.

Second, product characteristicsIt is like a game console joystick, you can control the joystick module input x, y, z ofValues, and to achieve a particular value in a function, it can be considered a combination ofbuttons and a potentiometer. DataType of x, y dimension for the analog input signal is a digital input signal z dimension, therefore,x and y connected to the analog portPin sensor end, and z port is connected to the digital port.

Third, the useOn how to use, we first look at how it works now, so we know it is there in the endHow, which we find it helpful to use, there is a functional diagram below, we take a lookNow we should clear it, in fact, it is a potentiometer Well, x, y dimension of the data output isanalogPort readout voltage value, is not a little surprised.
