I modified the TOMYTEC “THE Car Collection” 1/150 TOYOTA CROWN to work with a remote control. The car is controlled by a self-made infrared remote control.
The remote control format is proprietary.
The battery installed in the car is a lithium polymer battery(3.7V 40mAh).
I used motors by removing weights of the vibration motors.
In order to write the program of the microcontroller(ATtiny1616) used on the car, you need ATMEL STUDIO 7 or later and a device that can use UPDI.
I use MPLAB PICkit 4. AVRISP mkII cannot be used.
