In this part I will quickly summarize the week, it was strewn with pitfalls. All week, from Monday to Friday, we tried to print the parts with the 3D printer but the parts were never printed as we wanted.

Here are some failures

In the end, we decided to use both 3D prints and also laser-cut plexiglass to complete the last pieces that we were missing.

This week, we also managed to make the electronic part work. An arduino Nano is connected to a bluetooth module which allows to control the H-bridge and especially the motor. With the code, when the user sends "F" to the arduino, the motor spins in one direction. With "R" in another direction, and with "O" we stop the motor. On Friday, we got kicked out of the lab because it seems that 8:15 p.m. is too late and we have to leave school. And since the lab is closed Saturday and Sunday, we'll finish Monday, one day before the presentation.
