Arduino - это контроллер, который используется в electrical circuits for data processing. It can often be found in smart home systems. There are many modifications of this element, which differ in conductivity, voltage and maximum overload. It is also worth noting that the models are made with various components. If necessary, the device can be assembled by yourself. However, for this you should familiarize yourself with the modification scheme.
How does the Arduino controller work?
The conventional model includes a transistor,which works from an adapter, as well as a chain of transceivers. To support a stable current there is a relay. Contactors at controllers are used in different directions. Rectifier units at the controllers are installed with plates. Condensers in many models are available with low-frequency type filters.
Build Arduino UNO
If necessary, you can make the controllerArduino UNO do it yourself. For this purpose, two transceivers and one cover are used. Capacitors can be used with a conductivity of 50 microns. The operating frequency of the elements is at 300 Hz. To install the transistor control is used. Filters can be soldered at the beginning of the circuit. Quite often they are set to transitional type. In this case, transceivers are allowed to use the extension type.
Build Arduino UNO R3
Build an Arduino UNO R3 with your own hands prettysimply. To this end, you will need to prepare a transceiver of the transition type, which works from the adapter. The stabilizer can be used with a conductivity of 40 microns. The operating frequency of the controller will be about 400 Hz. Experts advise not to use conductor transistors, since they are not able to work with wave interference. Many models are made with self-regulated transceivers. Their connectors are connected with a conductivity of 340 microns. The rated voltage of the controllers in this series is at least 200 V.
Build modifications Arduino Mega
Make an Arduino Mega do it yourselfbased on the collector transceiver. Contactors are often installed with adapters, and their sensitivity is at least 2 mV. Some experts recommend the use of inverting filters, but we must remember that they can not work at a lower frequency. Transistors are used only conductor type. Rectifier unit is installed last. If there are problems with conductivity, experts recommend checking the rated voltage of the device and installing capacitive capacitors.
How to build Arduino Shield?
Build a controller Arduino Shield do it yourselfquite simple. To this end, the transceiver can be harvested for two adapters. The transistor can be used with a lining and conductivity of 40 microns. The operating frequency of the controller of this series is not less than 500 Hz. The element is operated at a voltage of 200 V. A regulator for modification will be required on the triode. The converter must be installed in order not to burn out the transceiver. Filters are often used with a variable type.
Build Arduino Nano
Arduino Nano do-it-yourself controllertwo transceivers. For assembly, a pole type stabilizer is used. In total, two small capacitors are required. The transistor is installed with a filter. The triode in this case is obliged to operate at a frequency of at least 400 Hz. The nominal voltage of the controllers of this series is 200 V. If we talk about other indicators, it is worth noting that the sensitivity is at least 3 mV. Relay for assembly will be required with a mesh filter.
SMD transistor assembly
To do with the SMD transistor smart home with your ownby hand (Arduino), only one transceiver is required. To maintain a stable frequency, two capacitors are installed. Their capacitance must be at least 5 pF. To install the thyristor used a conventional wired adapter. Stabilizers at the beginning of the circuit are mounted on a diode basis. The conductivity of the elements must be at least 55 microns. Attention should also be paid to the insulation of capacitors. To reduce the number of failures in the system, it is recommended to use only converter comparators with low sensitivity. It is also worth noting that there are wave analogues. Their sensitivity index is 200 mV. Regulators are only suitable for duplex type.
Model based on DA1
Transistors of this series have excellentconductivity and able to work with output converters of different frequencies. The user is able to make a modification on the basis of a wired transceiver. Its contacts are connected directly through a capacitor unit. It is also worth noting that the regulator is installed behind the transceiver.
When assembling the controller is recommended to usecapacitive triodes with low heat loss. They have high sensitivity, and conductivity is at the level of 55 microns. If a simple transition stabilizer is used, the filter is applied with the lining. Experts say that tetrodes are allowed to be installed with a comparator. However, it is necessary to take into account all the risks of failure of the capacitor unit.
Assembly transistor DD1
DD1 transistors provide high speedresponse with little heat loss. To assemble the Arduino controller with your own hands, it is recommended to prepare a transceiver. It is more expedient to use a linear analogue, which has high conductivity. It should also be noted that the market is overflowed with monopolar modifications, and their sensitivity index is at the level of 60 mV. For a quality controller, this is clearly not enough.
The controller is set as standard duplextype The triode for the model is selected on a diode basis. Directly comparator is installed at the beginning of the circuit. He is obliged to work at resistance not lower than 50 ohms. In this case, the rated voltage is about 230 V.
Model based on DD2
DD2 transistors are operated by conduction300 microns They have high sensitivity, but they can only work at high frequency. For this purpose, an expansion transceiver is installed on the controller. Next, to make the Arduino do it yourself, the wired switch is taken. The output contacts of the element are connected to the relay. Resistance at the switch must be at least 55 Ohms.
Additionally, it is worth checking the resistance oncondenser unit. If this parameter exceeds 30 ohms, the filter is used with the triode. Thyristor is installed with one stabilizer. In some cases, rectifiers are soldered behind the transistors. These elements not only maintain frequency stability, but also partially solve the problem with conductivity.
Assembly on the transistor L7805
Build an Arduino controller with your own hands (on the basetransistor L7805) is quite simple. A transceiver for the model is required with a mesh filter. The conductivity of the element must be at least 40 microns. Additionally it is worth noting that capacitors are allowed to use binary type. Experts say that the rated voltage should not be above 200 V. In this case, the sensitivity depends on many factors. The comparator is most often installed on the controller with a linear adapter. At the exit, the triode is soldered on a diode basis. A single-pass filter is used to stabilize the conversion process.
Model based on FT232RL
Чтобы правильно сделать контроллер Arduino своими hands, it is recommended to pick up a high-voltage transceiver. The conductivity of the element must be at least 400 microns with a sensitivity of 50 mV. The contactors in this case are installed at the output of the circuit. The relay is allowed to use low conductivity, but it is important to pay attention to the voltage limit indicator, which should not exceed 210 V. The triode can be installed only behind the lining.
Также стоит отметить, что для контроллера need one converter. The capacitor box is used with two low conductivity filters. The level of the output resistance of the element depends on the type of comparator. It is mainly used on a dipole adapter. However, there are impulse counterparts.
Assembling a controller with a 166HT1 transistor
Transistors of this series have400 micron conductivity, and they have good sensitivity. To make the controller with your own hands, it is recommended to use a dipole transceiver. However, filters for it are suitable only with winding. Experts say that the contactor should be installed with an adapter. In this case, the linear component is well suited, and the rated voltage in the circuit must be at least 200 V. Thus, the operating frequency of the controller will not fall below 35 Hz.
