Hi all, thanks for waiting. I've just uploaded new feature in our NRF24L01 transmitter for Arduino Drone with NRF24L01 + BMP180: 1 reset button. *PIN OF RESET BUTTON:* D2 pin to Reset Button GND pin to GND Reset Button The Reset Button is to delete Previous Trim Value of Pitch and Roll stored in EEPROM of Arduino board. It will save automatically when you press Pitch and Roll button as well as Reset Button. *PLEASE TAKE NOTICE CAREFULLY:* In " " file of github repo, you will see this code (inside "void updateTrimValues()" section: tRoll += 5; tRoll -= 5; tPitch += 5; tPitch -= 5; The value is "5". If the pitch and the roll is too sharp, you can reduce by modifying them into: 4, 3, 2, or 1. Based on your drone response. *You can also modify the safe range:* // Constrain trim values to a safe range tRoll = constrain(tRoll, -250, 250); tPitch = constrain(tPitch, -250, 250); *change into (such as):* // Constrain trim values to a safe range tRoll = constrain(tRoll, -50, 50); tPitch = constrain(tPitch, -50, 50); I already updated the schematic diagram and code in Github Repo: Batere 9v 6800 mAh untuk remote control: Please refers to file " " in the github repo. The code is full optimized code for our NRF24 drone project. Note: All schematic diagram has been revised and up to date. *Target Files You Need:* *PIN CONFIGURATION:* #specific-joystick--trimmers *SCHEMATIC DIAGRAM:* #full-schematic-diagram-for-specific-joystick *FINAL OPTIMIZED CODE:* *Previous Tutorial Video:* Part #1 (Standard NRF24 Transmitter): Part #2 (Upgraded NRF24 Transmitter): Recommended to use LCD with Specific Joystick to make if usable and provide information about our configuration through LCD display.
