How to Interface Stepper Motor With Arduino
https://www.electronics-lab.com/interface-stepper-motor-arduino/
This tutorial is going to teach you some basics on using Stepper Motor while interfacing with Arduino and Stepper Motor Driver. Bipolar Stepper Motor is DC motor that move in discrete steps. It has multiple coils that are organized in groups called “phases”. By energizing each phase in sequence, the motor will rotate, a step […]
LED current regulator has low dropout
https://www.electronics-lab.com/led-current-regulator-low-dropout/
Peter Demchenko @ edn.com This Design Idea circuit regulates the current through one or more LEDs, making it almost independent of supply voltage. Its main advantage is a very small dropout voltage, which can be less than 100mV. The design could find use on LED strips, where the voltage can vary along the length due […]
USB to RS485 converter
https://www.electronics-lab.com/usb-rs485-converter/
Marko Pavlin has published a USB to RS485 converter. He writes: Testing of sensors with RS485 using PC without proper interface is not possible. Since RS232 interfaces are very rare, the interface should be hooked to USB. The interface between USB and RS485 can be soldered with one of the many FTDI interfaces with added […]
Dual DC Motor Driver For Robot with L298
https://www.electronics-lab.com/dual-dc-motor-driver-robot-l298/
Dual Motor L298 H-Bridge Control project can control two DC motors connected to it. The circuit is designed around popular dual H-Bridge L298 from ST. This board can be configured to drive a single motor with high current rating also. This can be achieved with the help of jumpers on the board. An onboard 5V […]
ESP8266 + I2S = Software-based 10-Base-T Ethernet Driver
https://www.electronics-lab.com/esp8266-i2s-software-based-10-base-t-ethernet-driver/
cnlohr @ github.com wanted to have an Ethernet interface for ESP8266 so he build one. more details on hackaday. This is a relatively unreliable and coincidentally functional ESP8266 Ethernet driver. It only uses two pins on the ESP, the I2S pins, but does provide Ethernet. It does all its own manchester encoding/decoding, framing, FCS, etc. It […]

https://www.electronics-lab.com/dual-dc-motor-driver-using-two-l293d/
Dual DC Motor driver using two L293D IC. The L293D device is quadruple high-current half-H driver. The 293D is designed to provide bidirectional drive current up to 600mA a voltage from 5V to 36V. It provides 600mA +600mA on each channel suitable for mini hobby robots. The board been designed mainly for small size robot, […]
4A Bipolar Stepper Motor Driver Based on LV8727E
https://www.electronics-lab.com/4a-bipolar-stepper-motor-driver-based-on-lv8727e/
The Project is based on LV8727E IC from ON Semiconductor. The LV8727 is a PWM current-controlled micro step bipolar stepping motor driver. This driver can provide eight ways of micro step resolution of 1/2, 1/8, 1/16, 1/32, 1/64, 1/128, 1/10, 1/20, and can drive simply by the step input. This Bipolar Driver works with supply […]
