How about Arduina ESP32 mount OLED-screen I2C and why it stays empty?

When empty OLED-monitor check power supply, connection SDA/SCL, address I2C and the chosen driver. The same screen resolution does not necessarily mean the same…

How to ESP32 saving measurements at SD-card and prevent data loss?

For recording measurements at SD-the card needs a proper electrical interface, a proper file system and a controlled method of closing records. Cards Not…

I2C, SPI or UART: How do I choose the right connection for sensor and development plate?

I2C, SPI and UART are different methods of connecting devices. The choice should be determined by the actual interface of the module and the project requirements, not just the number of free..

When for Arduina or ESP32 use relays, MOSFET or SSR?

The relay is suitable for rarer switching, MOSFET for suitable low voltage DC-burden and often PWM, and SSR must be selected for a specific species…

Refrigerator miscools: how do I check if the problem is NTC-sensor?

Miscooling shall not constitute failure of the NTC. The cause may also be cable, connector, fan, defrosting, neck sealing or other part..

Can I replace the original fridge sensor with an INOX NTC-son of 10 kiloohms?

INOX NTC 10 k? is the appropriate replacement only if it corresponds to the original sensor specification. The metal casing and the nominal resistance alone do not prove..

NTC 10 or 100 kiloohms: how do I choose the right temperature sensor?

10 k? and 100 k? are the nominal resistances applicable at that reference temperature. The sensors aren't directly interchangeable just because they both measure..

Why do two NTC-types with the same resistance at room temperature later show different?

The same resistance at one temperature does not mean the same curve. B-values, tolerances and characteristics can vary throughout the work..

How to deal with Arduina or ESP32 measuring temperature with INOX NTC-probe?

Connect the NTC to the voltage divider with the known resistance, measure the voltage with the ADC and convert it into temperature with the corresponding characteristic..

Can I extend the NTC-prone cable, and how can I reduce the disruption in the industrial cabinet?

The NTC cable can only be extended taking into account the measurement error, environment and connection mode. In a two-wire measurement, the resistance of the conductors is part of the measured..

How does the controller detect a interrupted or short-circuit temperature sensor?

In addition to temperature, the controller shall monitor the validity of the sensor. Interruption, short circuit and outdated information must lead to a clear error and..

When do I select NTC-sun, Type K thermocouple or infrared temperature sensor?

NTC is a contact resistance sensor, the thermocouple generates temperature-dependent voltage and the infrared sensor assesses the surface temperature from radiation. The choice is..

When Do I Change PTFE-tube in 3D-tiskalniku and how to prepare her end properly?

PTFE-replace the tube when damaged, worn, deformed or the connection does not remain securely in place. The right end shape depends on the role of the pipe…

How do I select and set the TMC2208 driver for the NEMA 17 march engine?

TMC2208 select according to engine, module and control panel requirements. The NEMA 17 indicates the mechanical size of the flange, not the required current or compatibility..

Why 3D-tiskalnik lost steps and layers shift?

The delay of the layer occurs when the actual position of the axle does not follow the ordered steps. It could be mechanical slipping, obstruction, excessive acceleration or electrical or..

Why the Z axis causes repeated lines to 3D-izdelku and how to check T8-spindle?

Repeated lines along axis Z may be connected to a spindle, clutch, guidance or uneven extrusion. A periodic pattern is a clue for inspection, not..

Final switch or 3D Touch: what do I need to refer and settle the foundation?

The final switch normally determines the axis reference point. The 3D Touch probe can measure the position of the surface of the substrate; its use requires mechanical, electrical..
