Electronics DIY Kits
The products received are of best quality and packaging is good.. These type of diy kit is more preferable for beginners..the kit also include a circuit design guide which make the kit more valuable than most other kits without design guides.
I bought this for my 7 y/o son. I was worried at first that he might loose some tiny parts before he finish assembling but he did it well bu himself. He loves it! This type of toy is very educational, it stimulates the brain and helps them to be patient.
Very easy to use with Windows 10 and the Arduino IDE.It needs a reset button. You have to unplug to cycle power after changing the switch from program to uart,
Awesome product, my 7 year old daughter LOVED the project and LOVED seeing what she can accomplish! It is definitely a great purchase. Also, customer service was excellent, we were missing a part and within 4 days we received a whole new kit in the mail. Awesome buy!
Awesome build quality. Soldering wires onto motors was nice and easy. My first little robot I'm designing. Everything fits on the chassis so far. Everything works like it should. Perfect to get into building robots or anything. I've put 9v into the motors and havent had any problems. They do move pretty fast Haha.
I've used several of these so far, and been happy with all of them. I've connected them to an Arduino's 5v, gnd, and analog inputs. The only issue that I've seen is that they don't center exactly on 512--they center somewhere around 490 to 525 ish. But they move smoothly and evenly across the range.
Has two potentiometers that let you adjust the sensitivity and the timeout (duration that it reads high). Haven't seen any other PIR sensors with those options. Standard 3 pin output (+5v, GND, signal) and good documentation via a link.
