Ultrasonic range finder using 8051 mictrocontroller has been already published by me in this website. This time it is an ultrasonic range finder using arduino. HC-SR04 ultrasonic range finder module is used as the sensor here. The display consists of a three digit multiplexed seven segment disp...
The experimental data are collected with the help of an HC-SR04 ultrasonic distance sensor and an Arduino Uno board. The data are then graphed and analysed using Microsoft Excel in real-time. The experiment data can be used to investigate Hooke's law. The elastic constant of the spring, k...
As well as the simple robot programming environment, Open Roberta Lab can be used to programme some simple development boards, such as an Arduino, Senseboard or BOB3 board, directly, or as with the Microbit, directly or in simulation.
If it all goes well. You'll see a blinking LED positioned next to the L on your arduino. [ ] RX [ ] TX [*] POW [*] L <--- this light will start flashing Open theexamples/blink.jsprogram in an editor and look at the code. Its currently set to blink every 500ms. ...
fatal error: Adafruit_Sensor.h: No such file or directory After some digging, I found that it is also necessary to have theAdafruit Unified Sensor Libraryalso installed. So, I did it from Arduino IDE Library Manager (see picture above). After that, everything worked fine, same as we use...
IoT projects ideas on Home Automaton LoRa Robotics for engineering students using ESP32 ESP8266 NodeMCU Arduino explained with source code circuit
from time to time you have to reload the Micro:bit controller with a HEX file from makecode, you may have to do this the first time you use it with the Arduino IDE. Generally I see this issue when I try to open the serial port before it's ready. ...
