Other motor encoders should have similar connections.The connections are very basic:VCC –the 5-volt power supply input. GND –The Ground connection. CH A –Output A. CH B –Output B.We will see how to use this with an Arduino to measure the motor RPM very soon....
As our robot car chassis experiment will be using an Arduino Uno we have two interrupt pins available to us, pins 2 and 3. Internally the AVR processors that the Arduinos are based upon use interrupt numbers starting at zero, as opposed to using the pin numbers. Here is a chart that ex...
Once everything is savedcorrectlyopen "Drone_Controller.ino" in the Arduino IDE. If "PPMEncoder.cpp" or "PPMEncoder.h" are not already added to the file, click "Sketch" --> "Add File..." and add the necessary files. Don't upload it yet, there are some changes that may need to ...
This library enables you to use Interrupt from Hardware Timers on supported Arduino boards such as AVR, ESP8266, ESP32, SAMD, SAM DUE, nRF52, Teensy, etc. These Hardware Timers, using Interrupt, still work even if other functions are blocking. Moreover,
NSS,NRESET, andDIO0pins can be changed by usingLoRa.setPins(ss, reset, dio0).DIO0pin is optional, it is only needed for receive callback mode. IfDIO0pin is used, itmustbe interrupt capable viaattachInterrupt(...). NOTES: Some boards (like the Arduino Nano), cannot supply enough curre...
tab and click on TIM1 in the control block. Somewhat arbitrarily, set “Prescaler” to “10”, “Counter Period” to “200” and “Internal Clock Division” to “Division by 2”. Then, in that same pop-up window, go to the NVIC Settings and set TIM1 capt...
The delay allows the motor to accelerate/decelerate in accordance with the change in the PWM value. Operation will continue until the user presses the push button on the rotary encoder. On change of state between on and off, the PWM value is written to persistent storage (EEPROM) if the ...

(three for the HoverBot) are connected to one of the Arduino's inputs that are capable of hardware interrupts. The fact that three hardware interrupt pins are needed is the reason why HoverBot uses an Arduino Mega rather than a smaller and cheaper Uno or Nano (seehttps://www.arduino.cc...
