Arduino is a controller that is used in electrical circuits to process data. It can often be found in smart home systems. There are many modifications of this element, which differ in conductivity, voltage and ultimate load. It is also worth noting that the models are made with various components. If necessary, the device can be assembled independently. However, for this it is worth familiarizing yourself with the modification scheme.
How is the Arduino controller designed?
The usual model includes a transistor that runs on an adapter, as well as a transceiver circuit. To maintain a stable current there is a relay. Contactors for controllers are used in different directions. Rectifier blocks for controllers are installed with plates. Condensers in many models are available with low-pass filters.
Build Arduino UNO
If necessary, you can make an Arduino UNO controller yourself. For this purpose, two transceivers and one cover are used. Capacitors may be used with conductivity from 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 chain. Quite often they are installed in transition type. In this case, transceivers are allowed to use the expansion type.
Build Arduino UNO R3
Assembling the Arduino UNO R3 with your own hands is quite simple. For this purpose, it will be necessary to prepare a transceiver of a transition type, which works from an adapter. The stabilizer may be used with conductivity from 40 microns. The operating frequency of the controller will be about 400 Hz. Experts advise against using conductive transistors, since they are not able to work with wave interference. Many models are made with self-regulating transceivers. Connectors are connected with conductivity from 340 microns. The rated voltage of the controllers of this series is at least 200 V.
Assembly modification Arduino Mega
You can make an Arduino Mega with your own hands only on the basis of a 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 it must be remembered that they cannot work at a lower frequency. Transistors are used only conductor type. The rectifier unit is installed last. If there are problems with the conductivity, experts recommend checking the rated voltage of the device and supply capacitive capacitors.
How to assemble an Arduino Shield?
Assembling an Arduino Shield controller with your own hands is quite simple. For this purpose, the transceiver can be harvested on 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 at least 500 Hz. The element is operated at a voltage of 200 V. A regulator for modification is required on a triode. The converter must be installed so that the transceiver does not burn out. Filters are often used of variable type.
Build Arduino Nano
Do-it-yourself Arduino Nano controller is made with two transceivers. A pole type stabilizer is used for assembly. 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 rated 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. Assembly relays are required with a mesh filter.
SMD Transistor Assembly
To make a do-it-yourself smart home with an SMD transistor (Arduino), you need only one transceiver. To maintain a stable frequency, two capacitors are installed. Their capacitance must be at least 5 pF. To install a thyristor, a conventional wired adapter is used. The stabilizers at the beginning of the circuit are mounted on a diode base. The conductivity of the elements should be at least 55 microns. Also pay attention to the insulation of capacitors. To reduce the number of system malfunctions, it is recommended to use only converter comparators with low sensitivity. It is also worth noting that there are wave counterparts. The sensitivity indicator for them is 200 mV. Regulators are suitable only for duplex type.
DA1 based model
Transistors of this series have excellent conductivity and are able to work with output converters of different frequencies. The user is able to make a do-it-yourself modification based on a wire transceiver. Its contacts are connected directly through the capacitor block. 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 heat loss. They have high sensitivity, and conductivity is at the level of 55 microns. If you use a simple stabilizer transition type, the filter is applied with a lining. Experts say that tetrodes can be installed with a comparator. However, it is worth considering all the risks of malfunctions in the operation of the capacitor unit.
Assembly on the transistor DD1
Transistors DD1 provide a high response speed with negligible heat loss. To assemble the Arduino controller with your own hands, it is recommended to prepare the transceiver. It is more expedient to use a linear analogue with high conductivity. It should also be noted that the market is crowded with unipolar modifications, and their sensitivity indicator is at the level of 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 chain. He must work with a resistance of at least 50 ohms. The nominal voltage is required to be about 230 V.
DD2 based model
DD2 transistors are operated at a conductivity of 300 microns. They have high sensitivity, but they can only work at high frequencies. For this purpose, an expansion transceiver is installed on the controller. Next, to make the Arduino with your own hands, you take a wire switch. The output contacts of the element are connected to the relay. The resistance at the switch must be at least 55 ohms.
Additionally, it is worth checking the resistance on the capacitor block. If this parameter exceeds 30 Ohms, then the filter is used with a triode. The 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 conductivity problem.
Assembly on the transistor L7805
DIY assembly of an Arduino controller (based on the L7805 transistor) is quite simple. A transceiver for the model will be required with a mesh filter. The conductivity of the element should be at least 40 microns. Additionally, it is worth noting that capacitors are allowed to use the binary type. Experts say that the rated voltage should not be higher than 200 V. Moreover, the sensitivity depends on many factors. The comparator is most often installed on the controller with a linear adapter. At the output, a diode-based triode is soldered. To stabilize the conversion process, a single-junction filter is used.
FT232RL based model
To properly make an Arduino controller yourself, it is recommended to choose a high-voltage transceiver. The conductivity of the element must be at least 400 microns at a sensitivity of 50 mV. 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 limit voltage indicator, which should not exceed 210 V. The triode can be installed only behind the lining.
It is also worth noting that the controller will require one converter. A capacitor box is used with two low conductivity filters. The output impedance level of an element depends on the type of comparator. It is mainly used on a dipole adapter. However, there are impulse analogues.
Controller assembly with transistor 166HT1
Transistors of this series have a conductivity of 400 microns, and they have good sensitivity. To make the controller yourself, it is recommended to use a dipole transceiver. However, filters are only suitable for it with a winding. Experts say that the contactor should be installed with an adapter. In this case, the linear component is well suited, and the nominal voltage in the circuit must be at least 200 V. Thus, the operating frequency of the controller will not fall below 35 Hz.
