Let’s take a closer look at the NRF24L01 transceiver module. It uses the 2.4 GHz band and it can operate with baud rates from 250 kbps up to 2 Mbps. If used in open space and with lower baud rate its range can reach up to 100 meters. Here are complete specifications: How It Works...
In this tutorial we will learn how to wirelessly control the Arduino robot car that we made in the previous video. I will show you three different methods of wireless control, using the HC-05 Bluetooth module, the NRF24L01 transceiver module and the HC-12 l...
Pin connection of Arduino Uno with the Motor driver are as follows: Here, we are using a 7.4 li-ion battery to power the whole circuit. You can use any battery type from 6-12 volt. To move the robot, we need to use motors with low RPM but torque high enough to carry the weight...
Now, for the UNO to convert analog signal into digital signal, we need toUse ADC Channel of Arduino Uno, with the help of below functions: 1. analogRead(pin); 2. analogReference(); 3. analogReadResolution(bits); Arduino ADC channels have adefault reference value of 5V. This means we can...
A microncontroller (e.g., Arduino, PicAxe, etc.) Built from material of a bold, solid color. The ability to change directions and move. A magnetometer. I used the HMC5883L. They're like 2 USD on eBay. A wireless serial connection. Bluetooth, Xbee, and nRF24L01 would be my rec...
And yet, we were still trying to create a next generation product with better graphics and gameplay. This would require deep magic. There was one sweet-spot on that spreadsheet that intrigued me. We had some experience at using Nordic Semiconductor’s nRF24L01 radio chips. These are re...
Moreover, the control of the airplane is also 100% DIY, based on Arduino and the NRF24L01 module for the radio communication. Using the right joystick of the transmitter, we can control the ailerons and the elevator of the airplane, and using the left joystick we can control the rudder an...
I will use a 3S Li-Po battery which provides around 12V. For theradio communication we are using the NRF24L01 module, and for theBluetooth communication we are using the HC-05 Bluetooth module. I also included a simple voltage divider which will be used for monitoring the battery voltage and...
so you can check it out if case you need more details about it. There are also detailed tutorials on the NRF24l01 module, andhow to use brushless motors using Arduino. Nevertheless, the basic working principle is that the transmitter sends the Joysticks or potentiometers data to the receiver ...
