For this project I purchased joy it’s 4WD robot car kit. The chassis is pretty cool and it comes with 4 DC motors. In addition I used L298N motor driver and a HM 10 BLE module.

The idea: I’d like to control the car with my iPhone using Bluetooth.

Several days later….

Meanwhile I finished the car. As I found out, there are hundreds of sites on the web dealing with this exact car – you can also have a look at youtube. Therefore I will not post my experiences with this particular car. It is pretty easy to mount and also very easy to program. If you have difficulties, just copy and paste a code which is available online.
