Tip Cleaning procedure using FS-100 Tip Cleaning Paste: Oxidized tip:  Re-tinned:  For optimum performance, use the FS-100 paste in conjunction with the Hakko FT-700 tip polisher for increased oxide removal. 1. The suitable temperature for cleaning is around 350℃. 2. Tin the tip with the chemical paste FS-100 (to remove oxides). 3. Wipe out the chemical paste FS-100 left on the tip with a cleaning sponge or cleaning wire. 4. Feed solder to the tip and see whether or not solder wets on it. 5. Repeat the above steps of 2 to 4 until solder wets on the tip surface. 6....

The Infrared Sensor Module (TCRT5000) is a Line Tracking Module. It is an infrared distance module most used for object and obstacle detection, and robot applications like a line following robot car, product line decoder and much more.   This article will talk about the pinout and wiring of the module operating with an Arduino Board. At the end of the tutorial, you will learn how to build a line decoder to detect objects.  Wiring  The infrared module operates at 3V to 5V DC and produces a digital output. There are two different types of infrared modules in the market where...

The CAROBOT Motor Shield allows you to easily control motor direction and speed using an Arduino. By allowing you to simply address Arduino pins, it makes it very simple to incorporate a motor into your project. It also allows you to be able to power a motor with a separate power supply of up to 12v. For all of these reasons, this motor shield is a popular device that is commonly used in projects, such as robot cars, and much more.    In this article, we will talk about the setup and operation of the CAROBOT Motor shield with Arduino. ...

The HC-SR04 ultrasonic sensor module is a very popular module for measuring distance or any other purposes. It emits an ultrasound signal at about 40 000 Hz which travels through the air and if there is an object or obstacle along its path, the sound will bounce back to the module. In this article, we will talk about how to wire and set up the module for operation with an Arduino Board.   Wiring  Most HC-SR04 modules operate at 5V and gives out digital outputs. For this project, we will be using the HC-SR04 Ultrasonic Sensor module we carry in our shop. This module consists...

In this article, we will guide you on making a robot car that can follow a line. We will be using the parts that we carry in our shop.  We will be using CAROBOT Motor Driver and Servo Shield to make connected Motors to Arduino UNO. The shield separate the Uno's PWM digital pins (3,5,6,9,10,11) and the non-PWM digital pins (2,4,7,8,12,13) for easy identification. Furthermore, it provides a 5V and GND rail for easy connections. The Motor and Shield shield is equipped with an L298N H-Bridge Motor Driver. This allows the shield to drive two DC motors.  We will also be using...
