FAQ¶
Q1: Compilation error: SoftPWM.h: No such file or directory?¶
If you get a “Compilation error: SoftPWM.h: No such file or directory” prompt, it means you don’t have the SoftPWM
library installed.
Please refer to Install the Required Libraries to install the two required libraries SoftPWM
and IRLremote
.
Q2: avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x6e?¶
If the following message keeps appearing after clicking the Upload button when the board and port have been selected correctly.
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x00
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0x00
At this point, you need to make sure that the ESP32 CAM is unplugged.
The ESP32-CAM and the Arduino board share the same RX (receive) and TX (transmit) pins. So, when you’re uploading code, you’ll need to first disconnect the ESP32-CAM to avoid any conflicts or potential issues.
Q3: How can I use the STT feature on my Android device?¶
The STT feature requires the Android mobile device to be connected to the Internet and to install the Google service component.
Now follow the steps below.
Modify the AP mode of
Zeus_Car.ino
file to STA mode.Open the the
Zeus_Car.ino
file located in thezeus-car-main/Zeus_Car
directory.Then comment out the AP mode related code. Uncomment the STA mode related code and fill in the
SSD
andPASSWORD
of your home Wi-Fi./** Configure Wifi mode, SSID, password*/ // #define WIFI_MODE WIFI_MODE_AP // #define SSID "Zeus_Car" // #define PASSWORD "12345678" #define WIFI_MODE WIFI_MODE_STA #define SSID "xxxxxxxxxx" #define PASSWORD "xxxxxxxxxx"
Save this code, select the correct board (Arduino Uno) and port, then click the Upload button to upload it to the R3 board.
Search
google
in Google Play, find the app shown below and install it.Connect your mobile device to the same Wi-Fi as you wrote in the code.
Open the controller previously created in SunFounder Controller and connect it to
Zeus_Car
through the button.Tap and hold the widget after clicking the button. A prompt will appear indicating that it is listening. Say the following command to move the car.
stop
: All movements of the car can be stopped.pasue
: The function is basically the same as Stop, but if the head of the car is not facing the direction originally set, it will slowly move to the set direction.forward

left forward
left backward
