Resistor 10K Ohm 5% 0,25W 1/4W

NFC module for Educational STEAM Kit.  Near field communication (NFC) is a set of standards for smartphones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity, usually no more than a few centimeters. Compatible with almost any microcontroller, Arduino, PIC, AVR. It can be used in Access Control projects and Alarm projects. RFID PN532 NFC Module features:
- Based on the NXP PN532 chip, it can be used for non-contact communication of 13.56M.
- Greater effective communication distance of 3 cm.

Ideal for projects with ARDUINO, PIC, AVR, Raspberry
The infrared receiver receives the signal of 38kHz for remote control

4N35 DIP Optocoupler 30V 60mA - features:
-NPN Phototransistor Optocoupler

Isopropyl alcohol is used for cleaning: - Of electronic devices, such as contact tips (like those of ROM cartridges)
- Magnetic tapes and disc heads (such as those of audio and video recorders and floppy disk drives)
- Laser lenses in optical disk drives (for example: CD, DVD) and thermal paste removal from heat sinks and integrated circuit packages (for example: CPU) of the keyboard and LCD screen Very used in the cleaning of lenses of photographic lenses and contacts of electronic devices, since it does not leave marks and is of rapid evaporation. It is sold commercially also as a cleaner for slates.

The module uses a 24-bit high precision A/D conversion chip HX711.
The input circuit can be configured to provide a bridge.
The electric bridge voltage sensor model (such as pressure, weight) is an ideal sampling module with high precision and low cost. HX711 Module Weighing Pressure Sensor 24 Bits features:
- Two selectable differential input channels
- Active low noise PGA with selectable gain of 32, 64 and 128
- Power supply regulator for load cell and ADC analog power supply
- Oscillator on chip that does not require external component with optional external glass
- Power-on-reset on the chip
- Simple serial control and serial interface: controls driven by pins, programming is not required
- Output data rate 10SPS or 80SPS selectable

With this multiplexer circuit we will be able to get 8 more digital outputs for arduino losing only 3 of them.
