2.5A Bipolar Stepper Motor Driver using A3979
https://www.electronics-lab.com/2-5a-bipolar-stepper-motor-driver-using-a3979/
The tiny board designed using A3979 IC from ALLEGRO which is complete micro stepping driver with built in translator. The translator is the key to the easy implementation of the A3979. It allows the simple input of one pulse on the STEP pin to drive the motor one micro step, which can be either a […]
L293D Motor Direction Controller
https://www.electronics-lab.com/l293d-motor-direction-controller/
baelza.bubba @ instructables.com show us how to build a DC motor direction controller using L293D. I designed this DC Motor Direction Controller so that I could give direction control to DC motors that I am building into mini tools (drill, lathe, table saw, solder smoke extractor, etc.). While, I don’t need direction control for all […]
A DIY obstacle avoiding robot using an SG90 servo and Ultrasonic Sensor
https://www.electronics-lab.com/diy-obstacle-avoiding-robot-using-sg90-servo-ultrasonic-sensor/
In this video educ8s.tv shows us how to build an Arduino Robot that can avoid obstacles: The robot that we are going to build today is moving around and it can detect obstacles and avoid them. It uses a supersonic distance sensor in order to measure the distance from its front side. When it […]
12V NE555 PWM Controller
https://www.electronics-lab.com/12v-ne555-pwm-controller/
baelza.bubba @ instructables.com build his own PWM controller which is able to operate as a 12V Motor Speed Controller, LED Dimmer, Heat controller, voltage controller for an electrolytic etcher etc. I did some hunting around on the interweb and found a pretty good starting point in Circuits Today, but then, I needed to make […]
Wi-fi browser controlled servomotors
https://www.electronics-lab.com/wi-fi-browser-controlled-servomotors/
This instructable shows how to control some servomotors remotely in a wi-fi network, using an ordinary internet browser. This might be used in several applications: toys, robots, drones, camera pan/tilt, etc. The motors were attached to an Arduino Uno, which connects the wi-fi network through a ESP-8266 module. The control interface was designed with HTML […]

This tutorial shows how to interface DC motors using L293D motor driver IC and Arduino. Controlling DC motors with Arduino and L293 – [Link]
Heat Activated Cooling Fan Controller
https://www.electronics-lab.com/heat-activated-cooling-fan-controller/
Heat activated cooling fan controller is a simple project which operates a brushless fan when the temperature in a particular area goes above a set point, when temperature return normal, fan automatically turns off. The project is built using LM358 Op-amp and LM35 temperature Sensor. Project requires 12V DC supply and can drive 12V Fan. […]
ATtiny based bidirectional motor control using L293D
https://www.electronics-lab.com/attiny-based-bidirectional-motor-control-using-l293d/
Rahul @ Xanthium has posted a tutorial on interfacing ATtiny with L293D: In this tutorial we will learn to interface L293D with ATMEL ATtiny microcontroller and control them bidirectionally.The microcontroller used here is ATtiny2313A which is interfaced to two L293D motor control chips for controlling upto 4 DC brushed motors.You can control upto 8 motors if […]
1000 steps Servo motor
https://www.electronics-lab.com/1000-steps-servo-motor/
TheSuperSewcio @ instructables.com shows us how to control a servo motor in high precision using Arduino: In many project like CNC machines people use stepper motors. They are probably always more expensive than servos. They can rotate 360°, 1 step = 1,8° (mostly). Servos can rotate only from 0° to 180°, 1 step = 1°. But […]
