LCD; Moving Display & Custom Character : You can display your custom characters by using mikroc custom character tool. Go to tools>>customer character then make the character you want to display. After this click on 'generate code'. It will generate a customchar function just copy and paste above the main function. customchar has two parameters; row and position in that row. Just pass these parameters where you want to see your custom character on LCD. You can also move the text, left and right, on LCD screen; by using the LCD commands. _LCD_SHIFT_LEFT and   _LCD_SHIFT_RIGHT are the commands. There are various other commands in mikroc, i forget to tell you in lcd tutorial, these are: LCD Commands Now lets write a code to display and move the custom character, back and forth, (of your choice) on LCD screen. Code: // LCD module connections sbit LCD_RS at RB4_bit; sbit LCD_EN at RB5_bit; sbit LCD_D4 at RB0_bit; sbit LCD_D5 at RB1_bit; sbit LCD_D6 at RB2_bit; sbit LCD_D7 ...

There are a lot of reasons to put together a weather balloon launch. Its a great project for a STEM /STEAM class, it requires planning, electronics and programming, and teamwork. It has a lot of great classroom applications, giving a tangible demo of aerodynamics, physics, meteorology, geology, and more. Additionally its a great way to get amateur radio into the classroom and get a new generation into this great hobby. Outside of classrooms there is citizen science to be had, gathering your own data of atmospheric conditions or testing devices in space like conditions. And finally there are the amazing photos and videos that can be made only with weather balloons. Above all launching weather balloons is a lot of fun and a great challenge.

Timers Both PIC16f887 and 877 have three timers; timer 0, timer 1, and timer 2. Timer 0 is 8-bit and can also be use as counter, Timer 1 is 16-bit timer as well as a counter, where as Timer 2 is 8-bit timer and can be used as the PWM time base for the PWM mode of the CCP module(s).  Timer 0: The Timer0 module timer/counter has the following features: 8-bit timer/counter Readable and writable 8-bit software programmable prescaler Internal or external clock select Interrupt on overflow from FFh to 00h Edge select (rising or falling) for external clock Timer mode is selected by clearing bit T0CS (OPTION_REG<5>). In Timer mode, the Timer0 module will increment every instruction cycle (without prescaler). Counter mode is selected by setting bit T0CS (OPTION_REG<5>). In Counter mode, Timer0 will increment either on every rising or falling edge of pin RA4/T0CKI. The incrementing edge is determined by the Timer0 Source Edge Select bit, T0SE (OPTION_REG<4>). Clearing bit T...

This pinch project was realized with the ATM-18 controller module.This controller module has an ATmega88 microcontroller as and is a collaboration between Elektor and CC2 (Computer Club 2) . The Wii Nunchuk is addressed via the I2C interface. Resourceful tinkerers like Chad Phillips have the protocol and encryption algorithm found. Some possible application examples: Data Logger. Detect acceleration values ​​over a period of time and store them in an I2C EEPROM, eg damitr a drive to record. Pan-tilt camera control. A camera mounted on servo control over the Nunchuk. RC model remote control. Together with an RC transmitter to RC cars, robots and airplanes could control and so on. What is needed: WII Nunchuk € 19 Make a nunchuk adapter 5 $, or DIY yourself, or simply cut off the plug ATM-18 module or replica, it comes with an Arduino Board LCD module for display, alternatively UART connection Optional (but highly recommended): 3.3V voltage regulator bi-directional level shifter 3.3V / 5...
