The standard Gas or Electric RC cars are directional controlled by an electric servo that moving mechanical front steering wheel LeftRight.The servo have two main type-analog and digital.Analog servo is slower than digital but consume less power than digital servo.It depends on how fast the car will be applied.The steering servo shall be metal gear than plastic gear.Its more durable on tough road and serious crash. The standard Electric RC cars are drove by electric motors.The electric motors in RC have two main type Brushed and Brushless motor.For small or mini RC car,Brushed motors still favorite.For large scale or super fast RC car, Brushless motors are the best choice. RC car scale RC car scale 124 - 118 brushedbrushless motor size 180, 280, 370 RC car scale 110 brushedbrushless motor size 380 RC car scale 110 brushless motor size 380, 540 For this instruction, the prototype RC car use brushed motor 130 and 280. The RC car motor controlled by electronic speed control( ESC ).There are two type Brushed and Brushless ESC. The transmitter(Tx) has two potentiometers( Pot ),one for steering servo and one for electronic speed control (ESC). 2.4 Ghz Rc Receiver Code Through RadioPotentiometers will send code through radio system from transmitter(Tx) to receiver(Rx) to control Steering servo and ESC. 2.4 Ghz Rc Receiver Plus Arduino NanoThis project aim to resurrect low-brand sleepy FM transmitter by applying NRF24L01 module plus Arduino Nano.All unused control board have been removed, except potentiometers and some auxiliary switches to be hacked.Battery compartment has been modified for 2s Lipo 7.4V. Ah.(Ordinary 9V. Batt.,play too short time.) The hacked transmitter works well on traditional application.Unless its difficult on site adjustment like End point trimming,Steering trimming,Speed throttle curve,Brake adjustment where brand transmitter still be racing king. Thank to arduino-info.wikispaces.com, github.commaniacbugRF24 for RF24 library and other nRF24L01 module information. You can purchase electronic parts from Aliexpress, Banggod,Ebay,etc. Heat shrink tube 1.5 - 10 mm. Velcro tape 18. PCB - DIY circuit board 19. Battery Lipo 7.4 V. Ah 20. Unused 3-Channel RC transmitter(Pistol type with Steering wheel) Tools 1. Soldering gun. 2. Soldering wire. 3. Soldering paste. 4. Screw driver. 5. Plier. Hot glue gun. 7. Epoxy glue. Add Tip Ask Question Comment Download Step 2: Body Modification, Electronic Parts Installation DIY PCB Body modification DIY PCB 1. Open transmitter body up,remove unnecessary PCB,leave Steering potentiometer, ESC potentiometer and Auxiliary switch for hacking. Make DIY PCB according to circuit diagram.(See pin connection below) Soldering all devices carefully,use enough large wire.Making good ground. Cut off plastic body to open a hole for Nano USB. Modify battery compartment by cutting all plastic fins for more clear room.Paste Velcro tape on battery and compartment to fix battery in place. Attach DIY PCB and NRF24L01 module on opposite side of transmitter body by hot glue. Connection wiring between DIY PCB, Potentiometers, power switch and battery terminal. Before connecting main supply,check out to find short circuit points on DIY PCB.Otherwise it can smoke and burn everything.(Be careful of Lipo battery, its high current supply, short contact will spark fire) Arduino Nano to Pistol Transmitter Connection pin No: A3 - Steering servo potentiometer signal op A4 - ESC potentiometer signal op D4 - Auxiliary switch op nRF24L01 module Socket adaptor to Arduino Nano pin No: Vcc - 5 V. Its necessary to add 0.1 microF to nRF24L01 module pin VccGND because the module needs stable current and voltage.Also solder a small wire at the antenna to increase control range. Both code have to be divided by 10 to reduce value to two digit data before sending on radio.(See detail in attached sketch) 5. The sketch serial monitor will not show anything as video clip.We have to build receiver(Rx) on the car.Go to next instruction How to Hack RC Car Receiver via 2.4 GHz NRF24L01 Arduino Part 2 RxServoESC Attachments TxBoardV7-public.ino Download Add Tip Ask Question Comment Download.
