Arduino Tutorial – Make a Flex Sensor for Robotic Hand (Cheap and Simple)

In Arduino, Atal Tinkering Labs ATL, More Info | No comment

In this tutorial, we will learn how to make and use a flex sensor. We will control servo motor with a flex sensor.   Flex sensors are passive resistive devices that can be used to detect bending or flexing. The flex sensor shown in this tutorial is a flex sensor that decreases its resistance in proportion to the amount it is bent in either direction.You can easily make a sensor wider and longer depending upon your project.   Required Materials: – Paper – Flexible Cardboard or Plastic – Pencil – Aluminum Foil or Aluminum Tape – Wires – Solder or…

Arduino Project – Accelerometer Controlled Arduino Robot Car via Bluetooth

In Arduino, Atal Tinkering Labs ATL, More Info | No comment

Gyro Sensor Controlled Arduino Robot Car via Bluetooth.With G-sensor the robot will move depending on the slope of your smartphone. Joystick can be operated in the normal mode by moving the slider with your finger.   H-Bridge L293D: L293D is IC which is commonly used as a H-bridge. There are also other IC’s like L298 etc. but in this tutorial, we will see how we can use L293D. At the same time, you can use Motor driver chip L298N in this project.   Bluetooth Module: HC-06 chip of Bluetooth module soldered to the module board containing DC-DC converter and level…

Arduino Tutorial – Control your LEDs with TV or IR Remote

In Arduino, Atal Tinkering Labs ATL, More Info | No comment

In this tutorial we will learn how to control our LEDs with using TV or IR remote. After this tutorial, you can control everything with your TV or IR remote.   About IR : Infrared (IR) controls are often used in most electronic devices. This LED will give a predefined code when we press any key on the remote control and a certain frequency will also flash. The 38 kHz infrared receiver we use in the project demodulates the signal it receives and sends the button code to the Arduino. We can use with this receiver as long as different…

Arduino Tutorial – How to use DHT11 and DHT22 sensors

In Arduino, Atal Tinkering Labs ATL, More Info | No comment

In this tutorial we will learn how to use the DHT11 or the DHT22 sensor for measuring temperature and humidity. And we will see the value output of the DHT sensors on both the serial monitor and the LCD screen.The LCD screen component is optional. With this tutorial you can also print on a serial monitor. Code and circuit diagram are compatible within both sensors.   The DHT sensors have four pins, VCC, GND, data pin and a not connected pin which has no usage.   From left to right: 1 – VCC (5V) 2 – Signal 3 – NC…

Arduino Project – Remote Controlled Robot Car (TV – Infrared Remote (IR))

In Arduino, Atal Tinkering Labs ATL, More Info | No comment

In this tutorial we will learn how to control robot car with using TV or IR remote. Also we will use L298N H-bridge motor drive and Infrared Remote (IR) receiver.   IR library and tutorial: Infrared (IR) controls are often used in most electronic devices. The 38 kHz infrared receiver we use in the project demodulates the signal it receives and sends the button code to the Arduino. We can use with this receiver as long as different brand and model remote controls have 38 kHz carrier signal. The receiver has 3 pins. These are GND – VCC – Signal…
