Amazon. They're not too expensive. Here is the link for the pack I have
Hello :-)
You can use a simple (leaver) switch when it bumps into something (or indeed use the flex sensor), but better would be a ultra-sonic sensor ($1 at Aliexpress or eBay, $5 at Amazon). Another method is something like a tcrt5000 infrared distance sensor, but it's vulnerable to ambient light. You could do this with the photocell as well (or line tracking).
Also ad a $1 9g servo to pan the sensor :-)
What parts do you have besides the kit?
TL/DR: Just get started! All robots need basics coms, motors etc... Learn to control those and you'll find out exactly what you want to build after.
I am in the same boat, decided to build and program a robot from scratch. What the robot should do, I still dont know but I figured I should just get started with the basics; getting a processor communicating with a Motor and some basic sensors
Since I mostly wanted to get experience with hardware/software interface I got a raspberry pi and a robot chassis kit and started there.
Found a really good guide book that shows how to hook up a pi to sensors, motors, etc ... ISBN-13: 978-1119188681
Bought a chassis kit https://www.amazon.com/dp/B077HMY3YK/ref=cm_sw_r_cp_apa_i_Y.N5Ab2GXWV62
I also added a couple of arduinos sensors to play with.
If you want to use any custom firmware then don't upgrade. The latest upgrades encrypts the bluetooth which makes 3rd party apps and firmware flashing impossible.
DRV 155 is fine but as its a clone board BMS and BLE have to be flashed using the ST-Link method.
The documents say soldering but there is no need if you buy some pins for the ST-Link as clone motherboards have holes for the pins so that they are easy to flash.
Get ST-Link Get Pins
Put pins in ST-Link connectors
Plug ST-LINK into PC, set up ST-Link drivers and software
Download firmware needed to PC
Plug ST-Link leads into the correct holes on the clone board
Run the ST-Link software to flash the board
Done
Details are here for the whole thing including great firmware for heavier guys or for people faced with hills. Its the V9 firmware at the bottom of the page:

Here is the link for flashing the board with an ST-Link (follow the Pro guide):

And here is a link to a guy who did what I did

Here is the ST-Link I used

Good luck if you use the CW Firmware hills are a problem no more!
I asked massdrop support and they said any 2x3x4 mm square led would work and gave me this link note board only supports single color, not RGB leds
this could help, but I recommend using the splice method.
might want to start with something simpler to get the basics down such as an Arduino car kit and go from there
