In this tutorial, we will be building a simplearduino maze solving robot. The robot uses IR sensor to detect the maze and employs an algorithm called hand on wall rule to navigate through the maze and find the exit. Please note we have used lines to create the maze instead of building w...
I designed a custom PCB using the EasyEDA free online circuit design software. This PCB will actually act as an Arduino MEGA shield because we will be able to directly connect it on top of the Arduino Mega board. I used both the top and the bottom layer for running the connections...
println("Arduino for loop"); for (int i=0; i<7; i++) { Serial.print("i is : "); Serial.println(i); } } void loop(void) { } Notice how there are two statements - ending in semicolons and both are enclosed by curly braces. Compare this to the previous example that used ...
Track routing in Proteus PCB now displays a circular overlay which shows the design rule clearances around objects already placed on the board. This provides a clear view of where best to route. Watch Video Status Bar Updates The status bar at the bottom of the PCB layout has been updated...
Tlc.clear(); Tlc.update();delay(200); } }Code language:Arduino(arduino) Controlling more then one TLC5940 For connecting more then one of these ICs in series we can use the same circuit schematics as shown above. The only difference is that the SOUT (Signal Output – pin 17) of the...
The code below starts the AsynchronousReadFromArduino ArduinoThere are cases in which you might want to send parameters from Unity to Arduino. Let’s do this with an echo function. voidechoHandler(){ char*arg; arg = sCmd.next();
In main, execution loops on turning the LED on for 1 second, entering STOP 2 mode and then the RTC waking up the STM32 after 10 seconds. When the RTC wakes up the device, execution goes to the RTC ISR to clear some RTC fags and then goes back to main to continue ...

Copy Code TFT_eSPI tft = TFT_eSPI(screenWidth, screenHeight); TouchScreen ts = TouchScreen(XP, YP, XM, YM, 400);The program starts with the top-left calibration point visible and the counter set to zero.The Arduino sketch contains the same essential functions discussed in the previous ...
