“I would highly recommend this course because it provides excellent written instructions along with quality components. The written material is a wealth of information that is clearly designed to be used as a resource for any future electronics project. I see the written material and the wide range of components to be a worthwhile investment in my robotics future. Additionally, the support line is extremely responsive”

By Jeffrey P.

"I had no electronics experience at the beginning of this course but I appreciate the fact that (1) everything was clear, and (2) it worked as advertised. I now have have a great foundation to delve further into robotics/electronics world. Educational and fun experience."

By Paul H.

"Fills a huge void in accessible, working knowledge. Worth every penny and then some. You can not obtain this knowledge at any university. Appropriate for ANYONE at virtually any age seeking knowledge. My son loved it. I am grateful for the knowledge, as well."

Level D Robotics

This is an excellent program. My 12 year old son and I came to this program with no prior knowledge of electronics and have worked through all levels to finally build a mobile robot. Along the way we have learned to troubleshoot and persevere when things haven’t gone right first time - an extremely valuable life lesson! The course is well written and perfectly paced for beginners. The support provided by 42 Electronics is second to none. I have no hesitation in wholeheartedly recommending this course to anyone interested in electronics and robotics.

Excellent Home Robotics Program

We have owned Levels A-C since January and purchased D as soon as it came out. My son is in 8th grade. He did this whole program with very minimal help from his dad and me. He didn't really start working on the program until May, and was able to finish all 4 levels by mid July. We loved that this program uses real components and he was able to make a real robot. He can use everything he has learned to make new projects and figure out new problems. For everything that we got this set is a real value and a great introduction to work in technology fields. I recommend it to anyone showing an interest in technology and robotics.

Wonderful curriculum!

At first, I was hesitant to purchase this curriculum. I wasn't sure if this was a good fit for an older teen who has had some robotics experience. I am so thankful we purchased it. Level A filled in the gaps and taught him concepts he never fully understood or was never taught. The curriculum is detailed and easy to understand. He has now completed levels A-D and has enjoyed working with the robot and the Pi. The customer service of 42 Electronics has been amazing! Whenever we had a question or problem, they were super helpful! Thank you so much for creating this program. We would absolutely recommend this program!
