Project 16 – Driving two DC geared motors with MD10C by using SKPS

In this project, we will learn about how to drive two DC geared motor with MD10C by using SKPS. Thus, we will treat these two motors as the left wheel motor and right wheel motor. Therefore, we will use PS2 controller to control two DC motors in various type of movements such as move forward, move backward, rotate to left, rotate to right. In addition, we will use joystick to control these two motors in different movement with constant speed and variable speed. Meanwhile, we will use PIC16F887 in this tutorial for SK40C with LCD 2×16 to display some important messages when certain button of PS2 controller was pressed.

Method on interfacing and use the Flexiforce Sensors(A201)

The FlexiForce single element force sensor acts as a force sensing resistor in an electrical circuit. When the force sensor is unloaded, its resistance is very high. When a force is applied to the sensor, this resistance decreases. The resistance can be read by connecting a multimeter to the outer two pins, then applying a force to the sensing area. In this tutorial, you will going to learn on how to display the voltage level on 2×8 LCD and light up the LED based on the voltage level as the different force exerted to the Flexiforce Sensors(A201).

Identify Terminal Pins of A Relay Without Reference to Datasheet

Relays that normally used in electronic circuits are SPDT and DPDT types due to their flexibility in controlling circuit switching. In the next section, a demonstration on identifying the pins of a relay from SPDT or DPDT type without referring to its datasheet will be illustrated. A 5-pins type relay, a 6-pins type relay and an 8-pins type relay will be used in this demonstration.
