L9110S H Bridge Stepper Motor Dual DC Driver Controller Module For Arduino The L9110S dual channel h-bridge motor driver module is a compact board that can be used to drive small robots. This module is based on L9110 Motor Driver IC. This module has two independent motor driver chips which can each drive up to 800mA of continuous current. The boards can be operated from 2.5 volts to 12 Volts enabling this module to be used with both 3.3 Volts and 5 Volts microcontrollers. A set of female header pins and jumper wires are used to connect this module to a microcontroller like Arduino . The motors are attached via two sets of screw terminals. A PWM Pulse Width Modulation signal is used to control the speed of a motor and a digital output is used to change its direction. This module can also be used to drive a single four-line two-phase stepper motor. Four holes make this board easy to mount onto your robot or other projects. This dual-motor driver comes in a compact form factor and it is ideal for use in small robots. The actual direction of “forward” and “reverse” depends on how the motors are mounted and wired. You can always change the direction of a motor by reversing its wiring. The HG7881 (L9110) Dual Channel Motor Driver Module uses two of these motor driver chips. Each driver chip is intended to drive one motor, so having two means that this module can control two motors independently. Each motor channel uses the same truth table as above. Each set of screw terminals is used to connect a motor. Refer to the table below for pin header connections.

LC100A 2.5? LCD Digital High Precision Inductance Capacitance (LC) Meter The LC100A 2.5 LCD Digital High Precision Inductance/Capacitance (L/C) Meter can measure the capacitance of 1pF-100mF and the inductance of 1uH – 100H. Based on the principle of LC resonance, this instrument incorporates the precision measurement calculation of high-speed microcontroller. It can measure the inductance below 1uH and the small capacitance less than 1pF. Apart from measuring regular capacitor and inductor parts, an LC100-A LC meter can be the handy tool for measuring the inductance of your mini-quad motor windings, to determine if a particular motor has shorted turns or not. The biggest feature of the LC100A 2.5 LCD Digital High Precision Inductance/Capacitance (L/C) Meter is especially suitable for microwave production and measurement of switching power supply transformers and filter inductors. This product has an absolute advantage over small-value test in comparison with the finished inductor and capacitance meter (such as 6243 series) sold on the market. Degree and minimum resolution, and flexible online calibration can maintain measurement accuracy at any time; the instrument does not use any potentiometer adjustment. The calibration parameters are completely stored in the FLASH of the microcontroller after power loss data will not be lost. The calibration method is accurate and convenient. To make the LC100 a bit more workbench friendly, it features a few modifications. The LC100-A expects a 5V power supply, either by the USB connector or the coaxial DC socket. With the DC input socket, there is a risk of accidentally hooking up a supply of more than 5 volts, so a 5V regulator is being fitted, so that it can be powered off anything from 7 volts to the upper limit of the regulator (usually 35 volts). Measuring range position: C range - Capacitance (0.01pF-10uF) L range - Inductance (0.001uH-100mH) HL range - Big inductance (0.001mH-100H) HC range - Big capacitance range (1uF-100mF) Also check the T-66 Continuity Tester With 2 Button Cell available on the Iotcart website. It is a multi-purpose, lightweight continuity tester designed for checking electrical wires and power between two points.

Led Combo (R-G-Y-B-W) 5mm LEDs are used as indicator lamps in many devices and are increasingly used for other lighting. It looks like a white LED and illuminates blue light. When a light-emitting diode is switched on, electrons are able to recombine with holes within the device, releasing energy in the form of photons. This effect is called electroluminescence and the colour of the light (corresponding to the energy of the photon) is determined by the energy bandgap of the semiconductor. It is good quality and durable & small size and super bright LEDs with Low heat dissipation, energy-saving, and a long lifespan.
