We choseArduino hardware, as it is open source, has a huge support community, and the hardware and software are easy to use. It is also a very inexpensive introduction to do-it-yourself (DIY) electronics. Due to its small size and price, we used theArduino Nanofor this project. The pr...
and vice versa if all wheels move backward the robot will move backward. For moving to the right, the right wheels need rotate inside the robot, while the left wheels need rotate outside the robot. The resulting force due to the diagonally positioned rollers will make the robot move to the...
For this tutorial we have two examples. The first example is controlling a simple LED and the second one is controlling a Stepper Motor using smartphone. In myprevious tutorialwe already learned how to make the Bluetooth communication between the Arduino Board and the Smartphone ...
Battery and peripherals Then we'll go through a GPS tracker demo use case along with the Arduino code for it. Expand all 1. Sleep modes In many applications it is not needed to have the Spresense active at all times. If, for example, it is used as a g...
In this step-by-step tutorial, you'll discover how to use Arduino with Python to develop your own electronic projects. You'll learn how to set up circuits and write applications with the Firmata protocol. You'll control Arduino inputs and outputs and int

TheThread.sleep()method is a straightforward way to pause the execution of a Kotlin program for a specified amount of time. It takes a single argument, which represents the duration of the sleep in milliseconds. We can use theThread.sleep()function to make a coroutine go to sleep and allow...
The DHT11 uses just one signal wire to transmit data to the Arduino. Power comes from separate 5V and ground wires. A 10K Ohm pull-up resistor is needed between the signal line and 5V line to make sure the signal level stays high by default (see the datasheet for more info). ...
To read a Backup Register use the HAL function call, HAL_RTCEx_BKUPRead. To be able to write to the Backup register: Enable the PWR Clock (this is already done in the HAL Init function) Enable access to the backup domain Make a HAL function call to write the data: HAL_RTCEx_BKUPWr...
You may have also noticed that I put a sleep delay between LED commands sent to the Arduino. When I send them too close together, commands get dropped. This is likely a bug in my Arduino’s serial receiving code. I could have used an Arduino audio shield for playing sound, but I wa...
