Photosensitive Mobile Robot DIY Kit
User Manual
Introduction:
SFT-Q03YH is a Photosensitive Mobile Robot Simulation Firefly Electronic DIY
Kit.
It can simulate the automatic flashing of fireflies, and according to the
photosensitive sensor, it can automatically move towards the light at night.
It is a very interesting Mini DIY electronic product, which enables users to
understand the circuit more clearly and learn welding skills.
Parameter:
Product Name: Photosensitive Mobile Robot Electronic DIY Kit
Product Number: SFT-Q03YH
Work Voltage: DC 3V
Work Current:30mA
Work Temperature:-40℃~85℃
Work Humidity:5%~85%RH
Size(Installed):606035mm
Function:
- Sensitive movement: There are two photosensitive sensors on right and left (R1/R4) which simulate the antennae of fireflies. When the light reaches the antennae R1 or R4, Transistor Q1 or Q2 will turn ON, and then the corresponding motor starts to vibrate so that the firefly moves in the direction of light.
- Breathing light: The breathing lamp circuit is controlled by an lm358 chip, which can simulate the effect of the firefly’s slow ON and OFF. The LED breathing light will turn OFF when moving.
