Electrobot Starter Kit (70 ITEMS) 20+ DIY Projects with Electronics Components Breadboard, LEDs, Resistors, Switches etc

This kit will forever be special to me, as it is the one I began my electronics journey with. Doesn't look like it, but the assortment of parts inside it is enough to create a dozen interesting and non-trivial projects. The first thing I tried building was a simple alarm circuit to wake me up when sunlight hits my window using the active buzzer and LDR. It didn't work because lights in my room were extremely dim and the LDR wouldn't let through enough current to activate the buzzer. The internet introduced me to these wonderful devices called transistors, which can act as current amplifiers. And when I looked in my kit, it had five BC547 transistors! I added them to my circuit, and my alarm worked flawlessly. Next up, I built an Astable Multivibrator using two transistors. I got the inspiration from one of the other reviews posted here. I later to know that an even better way to build this would be using the 555 Timer IC. I looked into my kit, and lo and behold! It had two 555 timer IC's. Next I created all the gates - NOT, AND, OR, NAND, NOR and this kit always had whatever I needed. One thing that bugged me was that the kit did not have On-Off switches, only momentary push buttons. How do I turn my projects on and off, especially to conserve the battery? I was immensely frustrated that the kit did not include such a basic component! Searching for alternatives on the internet, I found out that the 555 Timer IC can also be used to build an SR Latch, which will convert the momentary push buttons into a proper On Off switch! I found all the necessary resistors and capacitors in the kit and successfully built it. Even the one limitation of the kit turned into a huge learning opportunity! Finally, I combined the 555 timer-based On-Off switch with an IR-based alarm (I had to buy IR Led and IR Receiver Diode separately), and created a safety device for my Grandmother; which was why I got electronics in the first place. With this, I completed my journey with this kit. Now, it certainly has its flaws. 1. 5k and 10k resistors should have been provided. I hate having to create these values by adding multiple smaller resistors in series. 2. 0.1uf capacitor should have been provided as it can be used to stabilize some circuits. 3. Seven Segment Display works, but it can display only one character with one wiring configuration. If you want to dynamically change the character displayed without rewiring, you will have to use a microcontroller (which you will buy anyway in the future). 4. Motor works, but what will you do with it on the breadboard? It will become useful in the future when you expand your hobby and buy microcontrollers and relays. 5. I wish IR Led and Receiver would have been included in the kit. None of these complaints are actual complaints but minor nitpickings. Thanks to this kit, today I know a thousand times more about electronics than I did a month ago. Now, I have purchased a much more advanced kit and will soon be moving on to microcontrollers like arduino. But this kit will forever hold a special place in my heart! It was my first, after all :) P.S. - I absolutely adore the cute little potentiometer. It was so useful in so many places.

most of the components were working fine. but the motor was very low quality. it was spinning very slowly. the switches were different than what was mentioned in the pictures. they didn't even fit in the breadboard. other than that it was worth the money

Bought this DIY kit. Looks amazing. Except that breadboard is smaller in size , all other components are good. The package comes with an QR code which upon scanning gives us the manual. Manual has many mini projects in detail.

Everything good but bread board size small

nice kit for starters.

Good

I received the material with 9 voltage discharged batteries 2 number, which are of no use. I have to throw these batteries.

This set contains so many different parts for the lowest price out there. This is the first time I've gotten into electronics and I learnt how to use all the parts that were included. All the parts work perfectly fine and there are plenty of projects you can build. I've attached one of my projects that u can build - a flickering led. It uses the 555 timer IC to build an oscillating circuit. Overall very happy with the parts. Don't expect any good packaging tho they're just different parts thrown into a cardboard box in different plastic packets. It doesnt include a manual either so u might find it hard to learn through YouTube. Ofcourse this is also safe for all ages.
