Arduino LCD Displays Wire up the arduino using these following instructions VCC (Red) to 5V Ground/GND (Black) to GND SDA (Blue) to A4 SCL (Yellow) to A5 The code used was downloaded adn the library installed in the specific location. Ensure that the LCD drivers are included in the same folder #include <Wire.h> // Comes […]
What is a stepper motor? A stepper motor uses opposing electromagnets to create rotation. The different number of steps are determined by the number of poles on each the stator and the rotor. There are several different types of stepper motor, depending on the use case and the size that is required. The main types […]
Pulse Width Modulation Using ‘unsigned char’ to replace values > ‘unsigned char’ allows you to control all of the same variables in a sketch by only changing one value unsigned char DelayTime = 255; unsigned char LEDoutput = 2; // the setup function runs once when you press reset or power the board […]
The task this week was to program the board that we made using the CNC router. There are several levels to this week, some being ‘simple’ and some being advanced. The main goal was to upload some sort of program to our Echo Hello World Plus board and ensure that it completed the function that […]
The task this week was to create the schematic, board layout and then mill the simple LED circuit board. Autodesk Eagle is the circuit-board software that we used > Installing it was relatively easy as it was just a simple installation but to get the correct components for the FAB LAB, downloading the library of […]
Surface mount components are very common and are what the majority of manufacturers will use due to the smaller size, compared to through components. It seems fairly easy to use them, although the mounting of these components, via soldering is vastly different to through hole components. Through hole components have the obvious advantage of being […]
