Arduino is a controller that is used in 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 limiting overload. It is also worth noting that the models are manufactured with various components. If necessary, the device can be assembled independently. However, for this it is worth to familiarize yourself with the modification scheme.
How is the Arduino controller arranged?
The conventional model includes a transistor that operates from an adapter, as well as a transceiver circuit. To maintain a stable current there is a relay. Contactors in controllers are used in different directions. The rectifier blocks of the controllers are installed with the plates. Capacitors in many models are available with filters of low-frequency type.
Building Arduino UNO
If necessary, you can make the controller Arduino UNO with your own hands. For this purpose, two transceivers and one lining are used. Condensers are allowed to be used with a conductivity of 50 microns. The operating frequency of the elements is at 300 Hz. A regulator is used to install the transistor. Filters can be soldered at the beginning of the circuit. Quite often they are installed in a transitional type. In this case, transceivers are allowed to use an expansion type.
Assembling Arduino UNO R3
It's quite easy to assemble Arduino UNO R3 with your own hands. To this end, you need to prepare a transient transceiver, which works from the adapter. The stabilizer is allowed to 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, because they are not able to work with wave interference. Many models are made with self-regulating transceivers. The connectors are connected with a conductivity of 340 microns. The nominal voltage for the controllers in this series is at least 200 V.
Assembly modification Arduino Mega
Make Arduino Mega own hands can only be based on the collector transceiver. Contactors are often installed with adapters, and their sensitivity is at least 2 mV. Some experts recommend using inverting filters, but we must remember that they can not work at a reduced frequency. Transistors are used only as a conductor type. The rectifier unit is installed last. If there are problems with conductivity, experts recommend checking the nominal voltage of the device and placing capacitive capacitors.
How to build Arduino Shield?
It's quite easy to assemble the Arduino Shield controller with your own hands. For this purpose, the transceiver can be harnessed to two adapters. The transistor is allowed to be used with a lining and conductivity of 40 μm. The operating frequency of the controller in this series is at least 500 Hz. The element is operated at a voltage of 200 V. The regulator is required for modification on a triode. The converter must be installed in order that the transceiver is not blown. Filters are often used in a variable type.
Assembling Arduino Nano
The Arduino Nano controller is made with two transceivers. The assembly uses a pole-type stabilizer. A total of two small capacitors are required. The transistor is installed with a filter. The triode in this case must 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, then it should be noted that the sensitivity is at least 3 mV. The assembly relay will be required with a grid filter.
Assembly of SMD transistors
To do with a SMD transistor a smart house with your own hands (Arduino), you only need one transceiver. To maintain a stable frequency, two condensers are installed. The capacity at them is obliged to make not less than 5 pF. To install the thyristor, a conventional wired adapter is used. Stabilizers at the beginning of the circuit are installed on a diode basis. The conductivity of the elements should be at least 55 microns. Also pay attention to the insulation of capacitors. To reduce the number of failures in the system operation, it is recommended to use only converter comparators with low sensitivity. It is also worth noting that there are wave analogues. The sensitivity index is 200 mV. The regulators are only suitable for duplex type.
Model based on DA1
Transistors of this series have excellent conductivity and are able to work with output converters of different frequencies. Make a modification with your own hands, the user is capable of using a conductor transceiver. Its contacts are connected directly through the condenser unit. It is also worth noting that the regulator is installed behind the transceiver.
When assembling the controller, it is recommended to use capacitive triodes with low thermal losses. They have high sensitivity, and conductivity is at the level of 55 microns. If you use a simple transient-type stabilizer, then the filter is applied with an overlay. Experts say that tetrodes can be installed with a comparator. However, it is worth considering all the risks of failures in the operation of the condenser unit.
Assembly on transistor DD1
Transistors DD1 provide high speed of response with insignificant heat losses. To assemble the Arduino controller yourself, it is recommended to prepare a transceiver. It is more expedient to use a linear analog with high conductivity. It should also be noted that the market is full of unipolar modifications, and the sensitivity index is at 60 mV. For a quality controller, this is clearly not enough.
The controller is standardly set to duplex type. The triode for the model is selected on a diode basis. Directly the comparator is installed at the beginning of the circuit. It must work with a resistance of at least 50 ohms. The nominal voltage must be about 230 V.
Model based on DD2
Transistors DD2 are operated at a conductivity of 300 microns. They have high sensitivity, but they are able to work only at a high frequency. For this purpose, an expansion transceiver is installed on the controller. Further, to make Arduino own hands, a conductor switch is taken. The output contacts of the element are connected to the relay. Resistance of the switch must be at least 55 ohms.
In addition, it is worth checking the resistance on the capacitor unit. If this parameter exceeds 30 Ohm, then the filter is used with a triode. Thyristor is installed with one stabilizer. In some cases, transistors are soldered to rectifiers. These elements not only maintain frequency stability, but also partially solve the conduction problem.
Assembly on a transistor L7805
To assemble Arduino controller by own hands (based on L7805 transistor) is quite simple. The transceiver for the model is required with a grid filter. The conductivity of the element should be at least 40 microns. In addition, it should be noted that capacitors are allowed to use a binary type. Experts say that the rated voltage should not be above 200 V. At the same time, the sensitivity depends on many factors. The comparator is usually mounted on a controller with a linear adapter. The output is soldered to a diode-based triode. To stabilize the conversion process, a unijunction filter is used.
Model based on FT232RL
To properly make the Arduino controller with your own hands, it is recommended to select 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, which should not exceed 210 V. The triode can only be installed behind the cover.
It is also worth noting that one controller is required for the controller. The capacitor box is used with two low conductivity filters. The output resistance level of the element depends on the type of comparator. It is mainly used on a dipole adapter. However, there are impulse counterparts.
The assembly of a controller with a transistor 166NT1
The transistors of this series have a conductivity of 400 microns, 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, a linear component is suitable, and the nominal voltage in the circuit must be at least 200 V. Thus, the operating frequency of the controller will not drop below 35 Hz.
